Views
=====
.. _reference/views/structure:
Common Structure
================
View objects expose a number of fields, they are optional unless specified
otherwise.
``name`` (mandatory)
only useful as a mnemonic/description of the view when looking for one in
a list of some sort
``model``
the model linked to the view, if applicable (it doesn't for QWeb views)
``priority``
client programs can request views by ``id``, or by ``(model, type)``. For
the latter, all the views for the right type and model will be searched,
and the one with the lowest ``priority`` number will be returned (it is
the "default view").
``priority`` also defines the order of application during :ref:`view
inheritance <reference/views/inheritance>`
``arch``
the description of the view's layout
``groups_id``
:class:`~odoo.fields.Many2many` field to the groups allowed to view/use
the current view
``inherit_id``
the current view's parent view, see :ref:`reference/views/inheritance`,
unset by default
``mode``
inheritance mode, see :ref:`reference/views/inheritance`. If
``inherit_id`` is unset the ``mode`` can only be ``primary``. If
``inherit_id`` is set, ``extension`` by default but can be explicitly set
to ``primary``
``application``
website feature defining togglable views. By default, views are always
applied
.. _reference/views/inheritance:
Inheritance
===========
View matching
-------------
* if a view is requested by ``(model, type)``, the view with the right model
and type, ``mode=primary`` and the lowest priority is matched
* when a view is requested by ``id``, if its mode is not ``primary`` its
*closest* parent with mode ``primary`` is matched
View resolution
---------------
Resolution generates the final ``arch`` for a requested/matched ``primary``
view:
#. if the view has a parent, the parent is fully resolved then the current
view's inheritance specs are applied
#. if the view has no parent, its ``arch`` is used as-is
#. the current view's children with mode ``extension`` are looked up and their
inheritance specs are applied depth-first (a child view is applied, then
its children, then its siblings)
The result of applying children views yields the final ``arch``
Inheritance specs
-----------------
Inheritance specs are comprised of an element locator, to match
the inherited element in the parent view, and children element that
will be used to modify the inherited element.
There are three types of element locators for matching a target element:
* An ``xpath`` element with an ``expr`` attribute. ``expr`` is an XPath_
expression\ [#hasclass]_ applied to the current ``arch``, the first node
it finds is the match
* a ``field`` element with a ``name`` attribute, matches the first ``field``
with the same ``name``. All other attributes are ignored during matching
* any other element: the first element with the same name and identical
attributes (ignoring ``position`` and ``version`` attributes) is matched
The inheritance spec may have an optional ``position`` attribute specifying
how the matched node should be altered:
``inside`` (default)
the content of the inheritance spec is appended to the matched node
``replace``
the content of the inheritance spec replaces the matched node.
Any text node containing only ``$0`` within the contents of the spec will
be replaced by a complete copy of the matched node, effectively wrapping
the matched node.
``after``
the content of the inheritance spec is added to the matched node's
parent, after the matched node
``before``
the content of the inheritance spec is added to the matched node's
parent, before the matched node
``attributes``
the content of the inheritance spec should be ``attribute`` elements
with a ``name`` attribute and an optional body:
* if the ``attribute`` element has a body, a new attributed named
after its ``name`` is created on the matched node with the
``attribute`` element's text as value
* if the ``attribute`` element has no body, the attribute named after
its ``name`` is removed from the matched node. If no such attribute
exists, an error is raised
A view's specs are applied sequentially.
.. _reference/views/list:
Lists
=====
The root element of list views is ``<tree>``\ [#treehistory]_. The list view's
root can have the following attributes:
``editable``
by default, selecting a list view's row opens the corresponding
:ref:`form view <reference/views/form>`. The ``editable`` attributes makes
the list view itself editable in-place.
Valid values are ``top`` and ``bottom``, making *new* records appear
respectively at the top or bottom of the list.
The architecture for the inline :ref:`form view <reference/views/form>` is
derived from the list view. Most attributes valid on a :ref:`form view
<reference/views/form>`'s fields and buttons are thus accepted by list
views although they may not have any meaning if the list view is
non-editable
``default_order``
overrides the ordering of the view, replacing the model's default order.
The value is a comma-separated list of fields, postfixed by ``desc`` to
sort in reverse order:
.. code-block:: xml
<tree default_order="sequence,name desc">
``colors``
.. deprecated:: 9.0
replaced by ``decoration-{$name}``
``fonts``
.. deprecated:: 9.0
replaced by ``decoration-{$name}``
``decoration-{$name}``
allow changing the style of a row's text based on the corresponding
record's attributes.
Values are Python expressions. For each record, the expression is evaluated
with the record's attributes as context values and if ``true``, the
corresponding style is applied to the row. Other context values are
``uid`` (the id of the current user) and ``current_date`` (the current date
as a string of the form ``yyyy-MM-dd``).
``{$name}`` can be ``bf`` (``font-weight: bold``), ``it``
(``font-style: italic``), or any `bootstrap contextual color
<http://getbootstrap.com/components/#available-variations>`_ (``danger``,
``info``, ``muted``, ``primary``, ``success`` or ``warning``).
``create``, ``edit``, ``delete``
allows *dis*\ abling the corresponding action in the view by setting the
corresponding attribute to ``false``
``on_write``
only makes sense on an ``editable`` list. Should be the name of a method
on the list's model. The method will be called with the ``id`` of a record
after having created or edited that record (in database).
The method should return a list of ids of other records to load or update.
``string``
alternative translatable label for the view
.. deprecated:: 8.0
not displayed anymore
.. toolbar attribute is for tree-tree views
Possible children elements of the list view are:
.. _reference/views/list/button:
``button``
displays a button in a list cell
``icon``
icon to use to display the button
``string``
* if there is no ``icon``, the button's text
* if there is an ``icon``, ``alt`` text for the icon
``type``
type of button, indicates how it clicking it affects Odoo:
``workflow`` (default)
sends a signal to a workflow. The button's ``name`` is the
workflow signal, the row's record is passed as argument to the
signal
``object``
call a method on the list's model. The button's ``name`` is the
method, which is called with the current row's record id and the
current context.
.. web client also supports a @args, which allows providing
additional arguments as JSON. Should that be documented? Does
not seem to be used anywhere
``action``
load an execute an ``ir.actions``, the button's ``name`` is the
database id of the action. The context is expanded with the list's
model (as ``active_model``), the current row's record
(``active_id``) and all the records currently loaded in the list
(``active_ids``, may be just a subset of the database records
matching the current search)
``name``
see ``type``
``args``
see ``type``
``attrs``
dynamic attributes based on record values.
A mapping of attributes to domains, domains are evaluated in the
context of the current row's record, if ``True`` the corresponding
attribute is set on the cell.
Possible attribute is ``invisible`` (hides the button).
``states``
shorthand for ``invisible`` ``attrs``: a list of states, comma separated,
requires that the model has a ``state`` field and that it is
used in the view.
Makes the button ``invisible`` if the record is *not* in one of the
listed states
.. danger::
Using ``states`` in combination with ``attrs`` may lead to
unexpected results as domains are combined with a logical AND.
``context``
merged into the view's context when performing the button's Odoo call
``confirm``
confirmation message to display (and for the user to accept) before
performing the button's Odoo call
.. declared but unused: help
``field``
defines a column where the corresponding field should be displayed for
each record. Can use the following attributes:
``name``
the name of the field to display in the current model. A given name
can only be used once per view
``string``
the title of the field's column (by default, uses the ``string`` of
the model's field)
``invisible``
fetches and stores the field, but doesn't display the column in the
table. Necessary for fields which shouldn't be displayed but are
used by e.g. ``@colors``
``groups``
lists the groups which should be able to see the field
``widget``
alternate representations for a field's display. Possible list view
values are:
``progressbar``
displays ``float`` fields as a progress bar.
``many2onebutton``
replaces the m2o field's value by a checkmark if the field is
filled, and a cross if it is not
``handle``
for ``sequence`` fields, instead of displaying the field's value
just displays a drag&drop icon
``sum``, ``avg``
displays the corresponding aggregate at the bottom of the column. The
aggregation is only computed on *currently displayed* records. The
aggregation operation must match the corresponding field's
``group_operator``
``attrs``
dynamic attributes based on record values. Only effects the current
field, so e.g. ``invisible`` will hide the field but leave the same
field of other records visible, it will not hide the column itself
.. note:: if the list view is ``editable``, any field attribute from the
:ref:`form view <reference/views/form>` is also valid and will
be used when setting up the inline form view
.. _reference/views/form:
Forms
=====
Form views are used to display the data from a single record. Their root
element is ``<form>``. They are composed of regular HTML_ with additional
structural and semantic components.
Structural components
---------------------
Structural components provide structure or "visual" features with little
logic. They are used as elements or sets of elements in form views.
``notebook``
defines a tabbed section. Each tab is defined through a ``page`` child
element. Pages can have the following attributes:
``string`` (required)
the title of the tab
``accesskey``
an HTML accesskey_
``attrs``
standard dynamic attributes based on record values
``group``
used to define column layouts in forms. By default, groups define 2 columns
and most direct children of groups take a single column. ``field`` direct
children of groups display a label by default, and the label and the field
itself have a colspan of 1 each.
The number of columns in a ``group`` can be customized using the ``col``
attribute, the number of columns taken by an element can be customized using
``colspan``.
Children are laid out horizontally (tries to fill the next column before
changing row).
Groups can have a ``string`` attribute, which is displayed as the group's
title
``newline``
only useful within ``group`` elements, ends the current row early and
immediately switches to a new row (without filling any remaining column
beforehand)
``separator``
small horizontal spacing, with a ``string`` attribute behaves as a section
title
``sheet``
can be used as a direct child to ``form`` for a narrower and more responsive
form layout
``header``
combined with ``sheet``, provides a full-width location above the sheet
itself, generally used to display workflow buttons and status widgets
Semantic components
-------------------
Semantic components tie into and allow interaction with the Odoo
system. Available semantic components are:
``button``
call into the Odoo system, similar to :ref:`list view buttons
<reference/views/list/button>`
``field``
renders (and allow edition of, possibly) a single field of the current
record. Possible attributes are:
``name`` (mandatory)
the name of the field to render
``widget``
fields have a default rendering based on their type
(e.g. :class:`~odoo.fields.Char`,
:class:`~odoo.fields.Many2one`). The ``widget`` attributes allows using
a different rendering method and context.
.. todo:: list of widgets
& options & specific attributes (e.g. widget=statusbar
statusbar_visible clickable)
``options``
JSON object specifying configuration option for the field's widget
(including default widgets)
``class``
HTML class to set on the generated element, common field classes are:
``oe_inline``
prevent the usual line break following fields
``oe_left``, ``oe_right``
floats_ the field to the corresponding direction
``oe_read_only``, ``oe_edit_only``
only displays the field in the corresponding form mode
``oe_no_button``
avoids displaying the navigation button in a
:class:`~odoo.fields.Many2one`
``oe_avatar``
for image fields, displays images as "avatar" (square, 90x90 maximum
size, some image decorations)
``groups``
only displays the field for specific users
``on_change``
calls the specified method when this field's value is edited, can generate
update other fields or display warnings for the user
.. deprecated:: 8.0
Use :func:`odoo.api.onchange` on the model
``attrs``
dynamic meta-parameters based on record values
``domain``
for relational fields only, filters to apply when displaying existing
records for selection
``context``
for relational fields only, context to pass when fetching possible values
``readonly``
display the field in both readonly and edition mode, but never make it
editable
``required``
generates an error and prevents saving the record if the field doesn't
have a value
``nolabel``
don't automatically display the field's label, only makes sense if the
field is a direct child of a ``group`` element
``placeholder``
help message to display in *empty* fields. Can replace field labels in
complex forms. *Should not* be an example of data as users are liable to
confuse placeholder text with filled fields
``mode``
for :class:`~odoo.fields.One2many`, display mode (view type) to use for
the field's linked records. One of ``tree``, ``form``, ``kanban`` or
``graph``. The default is ``tree`` (a list display)
``help``
tooltip displayed for users when hovering the field or its label
``filename``
for binary fields, name of the related field providing the name of the
file
``password``
indicates that a :class:`~odoo.fields.Char` field stores a password and
that its data shouldn't be displayed

Business Views guidelines
-------------------------
.. sectionauthor:: Aline Preillon, Raphael Collet
Business views are targeted at regular users, not advanced users. Examples
are: Opportunities, Products, Partners, Tasks, Projects, etc.
.. image:: forms/oppreadonly.png
:class: img-responsive
In general, a business view is composed of
1. a status bar on top (with technical or business flow),
2. a sheet in the middle (the form itself),
3. a bottom part with History and Comments.
Technically, the new form views are structured as follows in XML::
<form>
<header> ... content of the status bar ... </header>
<sheet> ... content of the sheet ... </sheet>
<div class="oe_chatter"> ... content of the bottom part ... </div>
</form>
The Status Bar
''''''''''''''
The purpose of the status bar is to show the status of the current record and
the action buttons.
.. image:: forms/status.png
:class: img-responsive
The Buttons
...........
The order of buttons follows the business flow. For instance, in a sale order,
the logical steps are:
1. Send the quotation
2. Confirm the quotation
3. Create the final invoice
4. Send the goods
Highlighted buttons (in red by default) emphasize the logical next step, to
help the user. It is usually the first active button. On the other hand,
:guilabel:`cancel` buttons *must* remain grey (normal). For instance, in
Invoice the button :guilabel:`Refund` must never be red.
Technically, buttons are highlighted by adding the class "oe_highlight"::
<button class="oe_highlight" name="..." type="..." states="..."/>
The Status
..........
Uses the ``statusbar`` widget, and shows the current state in red. States
common to all flows (for instance, a sale order begins as a quotation, then we
send it, then it becomes a full sale order, and finally it is done) should be
visible at all times but exceptions or states depending on particular sub-flow
should only be visible when current.
.. image:: forms/status1.png
:class: img-responsive
.. image:: forms/status2.png
:class: img-responsive
The states are shown following the order used in the field (the list in a
selection field, etc). States that are always visible are specified with the
attribute ``statusbar_visible``.
::
<field name="state" widget="statusbar"
statusbar_visible="draft,sent,progress,invoiced,done" />
The Sheet
'''''''''
All business views should look like a printed sheet:
.. image:: forms/sheet.png
:class: img-responsive
1. Elements inside a ``<form>`` or ``<page>`` do not define groups, elements
inside them are laid out according to normal HTML rules. They content can
be explicitly grouped using ``<group>`` or regular ``<div>`` elements.
2. By default, the element ``<group>`` defines two columns inside, unless an
attribute ``col="n"`` is used. The columns have the same width (1/n th of
the group's width). Use a ``<group>`` element to produce a column of fields.
3. To give a title to a section, add a ``string`` attribute to a ``<group>`` element::
<group string="Time-sensitive operations">
this replaces the former use of ``<separator string="XXX"/>``.
4. The ``<field>`` element does not produce a label, except as direct children
of a ``<group>`` element\ [#backwards-compatibility]_. Use :samp:`<label
for="{field_name}>` to produce a label of a field.
Sheet Headers
.............
Some sheets have headers with one or more fields, and the labels of those
fields are only shown in edit mode.
.. list-table::
:header-rows: 1
* - View mode
- Edit mode
* - .. image:: forms/header.png
:class: img-responsive
- .. image:: forms/header2.png
:class: img-responsive
Use HTML text, ``<div>``, ``<h1>``, ``<h2>``… to produce nice headers, and
``<label>`` with the class ``oe_edit_only`` to only display the field's label
in edit mode. The class ``oe_inline`` will make fields inline (instead of
blocks): content following the field will be displayed on the same line rather
than on the line below it. The form above is produced by the following XML::
<label for="name" class="oe_edit_only"/>
<h1><field name="name"/></h1>
<label for="planned_revenue" class="oe_edit_only"/>
<h2>
<field name="planned_revenue" class="oe_inline"/>
<field name="company_currency" class="oe_inline oe_edit_only"/> at
<field name="probability" class="oe_inline"/> % success rate
</h2>
Button Box
..........
Many relevant actions or links can be displayed in the form. For example, in
Opportunity form, the actions "Schedule a Call" and "Schedule a Meeting" have
an important place in the use of the CRM. Instead of placing them in the
"More" menu, put them directly in the sheet as buttons (on the top) to make
them more visible and more easily accessible.
.. image:: forms/header3.png
:class: img-responsive
Technically, the buttons are placed inside a ``<div>`` to group them as a
block on the top of the sheet.
::
<div class="oe_button_box" name="button_box">
<button string="Schedule/Log Call" name="..." type="action"/>
<button string="Schedule Meeting" name="action_makeMeeting" type="object"/>
</div>
Groups and Titles
.................
A column of fields is now produced with a ``<group>`` element, with an
optional title.
.. image:: forms/screenshot-03.png
:class: img-responsive
::
<group string="Payment Options">
<field name="writeoff_amount"/>
<field name="payment_option"/>
</group>
It is recommended to have two columns of fields on the form. For this, simply
put the ``<group>`` elements that contain the fields inside a top-level
``<group>`` element.
To make :ref:`view extension <reference/views/inheritance>` simpler, it is
recommended to put a ``name`` attribute on ``<group>`` elements, so new fields
can easily be added at the right place.
Special Case: Subtotals
~~~~~~~~~~~~~~~~~~~~~~~
Some classes are defined to render subtotals like in invoice forms:
.. image:: forms/screenshot-00.png
:class: img-responsive
::
<group class="oe_subtotal_footer">
<field name="amount_untaxed"/>
<field name="amount_tax"/>
<field name="amount_total" class="oe_subtotal_footer_separator"/>
<field name="residual" style="margin-top: 10px"/>
</group>
Placeholders and Inline Fields
..............................
Sometimes field labels make the form too complex. One can omit field labels,
and instead put a placeholder inside the field. The placeholder text is
visible only when the field is empty. The placeholder should tell what to
place inside the field, it *must not* be an example as they are often confused
with filled data.
One can also group fields together by rendering them "inline" inside an
explicit block element like ``<div>``. This allows grouping semantically
related fields as if they were a single (composite) fields.
The following example, taken from the *Leads* form, shows both placeholders and
inline fields (zip and city).
.. list-table::
:header-rows: 1
* - Edit mode
- View mode
* - .. image:: forms/placeholder.png
:class: img-responsive
- .. image:: forms/screenshot-01.png
:class: img-responsive
::
<group>
<label for="street" string="Address"/>
<div>
<field name="street" placeholder="Street..."/>
<field name="street2"/>
<div>
<field name="zip" class="oe_inline" placeholder="ZIP"/>
<field name="city" class="oe_inline" placeholder="City"/>
</div>
<field name="state_id" placeholder="State"/>
<field name="country_id" placeholder="Country"/>
</div>
</group>
Images
......
Images, like avatars, should be displayed on the right of the sheet. The
product form looks like:
.. image:: forms/screenshot-02.png
:class: img-responsive
The form above contains a <sheet> element that starts with:
::
<field name="product_image" widget="image" class="oe_avatar oe_right"/>
Tags
....
Most :class:`~odoo.fields.Many2many` fields, like categories, are better
rendered as a list of tags. Use the widget ``many2many_tags`` for this:
.. image:: forms/screenshot-04.png
:class: img-responsive
::
<field name="category_id" widget="many2many_tags"/>
Configuration forms guidelines
------------------------------
Examples of configuration forms: Stages, Leave Type, etc. This concerns all
menu items under Configuration of each application (like Sales/Configuration).
.. image:: forms/nosheet.png
:class: img-responsive
1. no header (because no state, no workflow, no button)
2. no sheet
Dialog forms guidelines
-----------------------
Example: "Schedule a Call" from an opportunity.
.. image:: forms/wizard-popup.png
:class: img-responsive
1. avoid separators (the title is already in the popup title bar, so another
separator is not relevant)
2. avoid cancel buttons (user generally close the popup window to get the same
effect)
3. action buttons must be highlighted (red)
4. when there is a text area, use a placeholder instead of a label or a
separator
5. like in regular form views, put buttons in the <header> element
Configuration Wizards guidelines
--------------------------------
Example: Settings / Configuration / Sales.
1. always in line (no popup)
2. no sheet
3. keep the cancel button (users cannot close the window)
4. the button "Apply" must be red
.. _reference/views/graph:
Graphs
======
The graph view is used to visualize aggregations over a number of records or
record groups. Its root element is ``<graph>`` which can take the following
attributes:
``type``
one of ``bar`` (default), ``pie`` and ``line``, the type of graph to use
``stacked``
only used for ``bar`` charts. If present and set to ``True``, stacks bars
within a group
The only allowed element within a graph view is ``field`` which can have the
following attributes:
``name`` (required)
the name of a field to use in a graph view. If used for grouping (rather
than aggregating)
``type``
indicates whether the field should be used as a grouping criteria or as an
aggregated value within a group. Possible values are:
``row`` (default)
groups by the specified field. All graph types support at least one level
of grouping, some may support more. For pivot views, each group gets its
own row.
``col``
only used by pivot tables, creates column-wise groups
``measure``
field to aggregate within a group
``interval``
on date and datetime fields, groups by the specified interval (``day``,
``week``, ``month``, ``quarter`` or ``year``) instead of grouping on the
specific datetime (fixed second resolution) or date (fixed day resolution).
.. warning::
graph view aggregations are performed on database content, non-stored
function fields can not be used in graph views
Pivots
------
The pivot view is used to visualize aggregations as a `pivot table`_. Its root
element is ``<pivot>`` which can take the following attributes:
``disable_linking``
Set to ``True`` to remove table cell's links to list view.
``display_quantity``
Set to ``true`` to display the Quantity column by default.
The elements allowed within a pivot view are the same as for the graph view.
.. _reference/views/kanban:
Kanban
======
The kanban view is a `kanban board`_ visualisation: it displays records as
"cards", halfway between a :ref:`list view <reference/views/list>` and a
non-editable :ref:`form view <reference/views/form>`. Records may be grouped
in columns for use in workflow visualisation or manipulation (e.g. tasks or
work-progress management), or ungrouped (used simply to visualize records).
The root element of the Kanban view is ``<kanban>``, it can use the following
attributes:
``default_group_by``
whether the kanban view should be grouped if no grouping is specified via
the action or the current search. Should be the name of the field to group
by when no grouping is otherwise specified
``default_order``
cards sorting order used if the user has not already sorted the records (via
the list view)
``class``
adds HTML classes to the root HTML element of the Kanban view
``group_create``
whether the "Add a new column" bar is visible or not. Default: true.
``group_delete``
whether groups can be deleted via the context menu. Default: true.
``group_edit``
whether groups can be edited via the context menu. Default: true.
``quick_create``
whether it should be possible to create records without switching to the
form view. By default, ``quick_create`` is enabled when the Kanban view is
grouped, and disabled when not.
Set to ``true`` to always enable it, and to ``false`` to always disable it.
Possible children of the view element are:
``field``
declares fields to use in kanban *logic*. If the field is simply displayed in
the kanban view, it does not need to be pre-declared.
Possible attributes are:
``name`` (required)
the name of the field to fetch
``templates``
defines a list of :ref:`reference/qweb` templates. Cards definition may be
split into multiple templates for clarity, but kanban views *must* define at
least one root template ``kanban-box``, which will be rendered once for each
record.
The kanban view uses mostly-standard :ref:`javascript qweb
<reference/qweb/javascript>` and provides the following context variables:
``instance``
the current :ref:`reference/javascript/client` instance
``widget``
the current :js:class:`KanbanRecord`, can be used to fetch some
meta-information. These methods are also available directly in the
template context and don't need to be accessed via ``widget``
``record``
an object with all the requested fields as its attributes. Each field has
two attributes ``value`` and ``raw_value``, the former is formatted
according to current user parameters, the latter is the direct value from
a :meth:`~odoo.models.Model.read` (except for date and datetime fields
that are `formatted according to user's locale
<https://github.com/odoo/odoo/blob/a678bd4e/addons/web_kanban/static/src/js/kanban_record.js#L102>`_)
``formats``
the :js:class:`web.formats` module to manipulate and convert values
``read_only_mode``
self-explanatory
.. rubric:: buttons and fields
While most of the Kanban templates are standard :ref:`reference/qweb`, the
Kanban view processes ``field``, ``button`` and ``a`` elements specially:
* by default fields are replaced by their formatted value, unless they
match specific kanban view widgets
.. todo:: list widgets?
* buttons and links with a ``type`` attribute become perform Odoo-related
operations rather than their standard HTML function. Possible types are:
``action``, ``object``
standard behavior for :ref:`Odoo buttons
<reference/views/list/button>`, most attributes relevant to standard
Odoo buttons can be used.
``open``
opens the card's record in the form view in read-only mode
``edit``
opens the card's record in the form view in editable mode
``delete``
deletes the card's record and removes the card

Javascript API
--------------
.. js:class:: KanbanRecord
:js:class:`Widget` handling the rendering of a single record to a
card. Available within its own rendering as ``widget`` in the template
context.
.. js:function:: kanban_color(raw_value)
Converts a color segmentation value to a kanban color class
:samp:`oe_kanban_color_{color_index}`. The built-in CSS provides classes
up to a ``color_index`` of 9.
.. js:function:: kanban_getcolor(raw_value)
Converts a color segmentation value to a color index (between 0 and 9 by
default). Color segmentation values can be either numbers or strings.
.. js:function:: kanban_image(model, field, id[, cache][, options])
Generates the URL to the specified field as an image access.
:param String model: model hosting the image
:param String field: name of the field holding the image data
:param id: identifier of the record contaning the image to display
:param Number cache: caching duration (in seconds) of the browser
default should be overridden. ``0`` disables
caching entirely
:returns: an image URL
.. warning::
``kanban_text_ellipsis`` has been removed in Odoo 9. CSS ``text-overflow`` should be used instead.
.. _reference/views/calendar:
Calendar
========
Calendar views display records as events in a daily, weekly or monthly
calendar. Their root element is ``<calendar>``. Available attributes on the
calendar view are:
``date_start`` (required)
name of the record's field holding the start date for the event
``date_stop``
name of the record's field holding the end date for the event, if
``date_stop`` is provided records become movable (via drag and drop)
directly in the calendar
``date_delay``
alternative to ``date_stop``, provides the duration of the event instead of
its end date
.. todo:: what's the unit? Does it allow moving the record?
``color``
name of a record field to use for *color segmentation*. Records in the
same color segment are allocated the same highlight color in the calendar,
colors are allocated semi-randomly.
``event_open_popup``
opens the event in a dialog instead of switching to the form view, disabled
by default
``quick_add``
enables quick-event creation on click: only asks the user for a ``name``
and tries to create a new event with just that and the clicked event
time. Falls back to a full form dialog if the quick creation fails
``display``
format string for event display, field names should be within brackets
``[`` and ``]``
``all_day``
name of a boolean field on the record indicating whether the corresponding
event is flagged as day-long (and duration is irrelevant)
``mode``
Default display mode when loading the calendar.
Possible attributes are: ``day``, ``week``, ``month``
.. todo::
what's the purpose of ``<field>`` inside a calendar view?
.. todo::
calendar code is an unreadable mess, no idea what these things are:
* ``attendee``
* ``avatar_model``
* ``use_contacts``
calendar code also seems to refer to multiple additional attributes of
unknown purpose
.. _reference/views/gantt:
Gantt
=====
Gantt views appropriately display Gantt charts (for scheduling).
The root element of gantt views is ``<gantt/>``, it has no children but can
take the following attributes:
``date_start`` (required)
name of the field providing the start datetime of the event for each
record.
``date_stop``
name of the field providing the end duration of the event for each
record. Can be replaced by ``date_delay``. One (and only one) of
``date_stop`` and ``date_delay`` must be provided.
If the field is ``False`` for a record, it's assumed to be a "point event"
and the end date will be set to the start date
``date_delay``
name of the field providing the duration of the event
``duration_unit``
one of ``minute``, ``hour`` (default), ``day``, ``week``, ``month``, ``year``
``default_group_by``
name of a field to group tasks by
``type``
``gantt`` classic gantt view (default)
``consolidate`` values of the first children are consolidated in the gantt's task
``planning`` children are displayed in the gantt's task
``consolidation``
field name to display consolidation value in record cell
``consolidation_max``
dictionary with the "group by" field as key and the maximum consolidation
value that can be reached before displaying the cell in red
(e.g. ``{"user_id": 100}``)
.. warning::
The dictionnary definition must use double-quotes, ``{'user_id': 100}`` is
not a valid value
``string``
string to display next to the consolidation value, if not specified, the label
of the consolidation field will be used
``fold_last_level``
If a value is set, the last grouping level is folded
``round_dnd_dates``
enables rounding the task's start and end dates to the nearest scale marks
``drag_resize``
resizing of the tasks, default is ``true``
.. ``progress``
name of a field providing the completion percentage for the record's event,
between 0 and 100
.. consolidation_exclude
.. consolidation_color
.. _reference/views/diagram:
Diagram
=======
The diagram view can be used to display directed graphs of records. The root
element is ``<diagram>`` and takes no attributes.
Possible children of the diagram view are:
``node`` (required, 1)
Defines the nodes of the graph. Its attributes are:
``object``
the node's Odoo model
``shape``
conditional shape mapping similar to colors and fonts in :ref:`the list
view <reference/views/list>`. The only valid shape is ``rectangle`` (the
default shape is an ellipsis)
``bgcolor``
same as ``shape``, but conditionally maps a background color for
nodes. The default background color is white, the only valid alternative
is ``grey``.
``arrow`` (required, 1)
Defines the directed edges of the graph. Its attributes are:
``object`` (required)
the edge's Odoo model
``source`` (required)
:class:`~odoo.fields.Many2one` field of the edge's model pointing to
the edge's source node record
``destination`` (required)
:class:`~odoo.fields.Many2one` field of the edge's model pointing to
the edge's destination node record
``label``
Python list of attributes (as quoted strings). The corresponding
attributes's values will be concatenated and displayed as the edge's
label
``label``
Explanatory note for the diagram, the ``string`` attribute defines the
note's content. Each ``label`` is output as a paragraph in the diagram
header, easily visible but without any special emphasis.
.. _reference/views/search:
Search
======
Search views are a break from previous view types in that they don't display
*content*: although they apply to a specific model, they are used to filter
other view's content (generally aggregated views
e.g. :ref:`reference/views/list` or :ref:`reference/views/graph`). Beyond that
difference in use case, they are defined the same way.
The root element of search views is ``<search>``. It takes no attributes.
.. @string is not displayed anywhere, should be removed
Possible children elements of the search view are:
``field``
fields define domains or contexts with user-provided values. When search
domains are generated, field domains are composed with one another and
with filters using **AND**.
Fields can have the following attributes:
``name``
the name of the field to filter on
``string``
the field's label
``operator``
by default, fields generate domains of the form :samp:`[({name},
{operator}, {provided_value})]` where ``name`` is the field's name and
``provided_value`` is the value provided by the user, possibly
filtered or transformed (e.g. a user is expected to provide the
*label* of a selection field's value, not the value itself).
The ``operator`` attribute allows overriding the default operator,
which depends on the field's type (e.g. ``=`` for float fields but
``ilike`` for char fields)
``filter_domain``
complete domain to use as the field's search domain, can use a
``self`` variable to inject the provided value in the custom
domain. Can be used to generate significantly more flexible domains
than ``operator`` alone (e.g. searches on multiple fields at once)
If both ``operator`` and ``filter_domain`` are provided,
``filter_domain`` takes precedence.
``context``
allows adding context keys, including the user-provided value (which
as for ``domain`` is available as a ``self`` variable). By default,
fields don't generate domains.
.. note:: the domain and context are inclusive and both are generated
if a ``context`` is specified. To only generate context
values, set ``filter_domain`` to an empty list:
``filter_domain="[]"``
``groups``
make the field only available to specific users
``widget``
use specific search widget for the field (the only use case in
standard Odoo 8.0 is a ``selection`` widget for
:class:`~odoo.fields.Many2one` fields)
``domain``
if the field can provide an auto-completion
(e.g. :class:`~odoo.fields.Many2one`), filters the possible
completion results.
``filter``
a filter is a predefined toggle in the search view, it can only be enabled
or disabled. Its main purposes are to add data to the search context (the
context passed to the data view for searching/filtering), or to append new
sections to the search filter.
Filters can have the following attributes:
``string`` (required)
the label of the filter
``domain``
an Odoo :ref:`domain <reference/orm/domains>`, will be appended to the
action's domain as part of the search domain
``context``
a Python dictionary, merged into the action's domain to generate the
search domain
``name``
logical name for the filter, can be used to :ref:`enable it by default
<reference/views/search/defaults>`, can also be used as
:ref:`inheritance hook <reference/views/inheritance>`
``help``
a longer explanatory text for the filter, may be displayed as a
tooltip
``groups``
makes a filter only available to specific users
.. tip::
.. versionadded:: 7.0
Sequences of filters (without non-filters separating them) are treated
as inclusively composited: they will be composed with ``OR`` rather
than the usual ``AND``, e.g.
::
<filter domain="[('state', '=', 'draft')]"/>
<filter domain="[('state', '=', 'done')]"/>
if both filters are selected, will select the records whose ``state``
is ``draft`` or ``done``, but
::
<filter domain="[('state', '=', 'draft')]"/>
<separator/>
<filter domain="[('delay', '<', 15)]"/>
if both filters are selected, will select the records whose ``state``
is ``draft`` **and** ``delay`` is below 15.
``separator``
can be used to separates groups of filters in simple search views
``group``
can be used to separate groups of filters, more readable than
``separator`` in complex search views
.. _reference/views/search/defaults:
Search defaults
---------------
Search fields and filters can be configured through the action's ``context``
using :samp:`search_default_{name}` keys. For fields, the value should be the
value to set in the field, for filters it's a boolean value. For instance,
assuming ``foo`` is a field and ``bar`` is a filter an action context of:
.. code-block:: python
{
'search_default_foo': 'acro',
'search_default_bar': 1
}
will automatically enable the ``bar`` filter and search the ``foo`` field for
*acro*.
.. _reference/views/qweb:
QWeb
====
QWeb views are standard :ref:`reference/qweb` templates inside a view's
``arch``. They don't have a specific root element.
A QWeb view can only contain a single template\ [#template_inherit]_, and the
template's name *must* match the view's complete (including module name)
:term:`external id`.
:ref:`reference/data/template` should be used as a shortcut to define QWeb
views.
.. [#backwards-compatibility] for backwards compatibility reasons
.. [#hasclass] an extension function is added for simpler matching in QWeb
views: ``hasclass(*classes)`` matches if the context node has
all the specified classes
.. [#treehistory] for historical reasons, it has its origin in tree-type views
later repurposed to a more table/list-type display
.. [#template_inherit] or no template if it's an inherited view, then :ref:`it
should only contain xpath elements
<reference/views/inheritance>`
