|
|
Style Hooks
|
|
-----------
|
|
|
|
The list view provides a few style hook classes for re-styling of list views in
|
|
various situations:
|
|
|
|
``.oe_list``
|
|
|
|
The root element of the list view, styling rules should be rooted
|
|
on that class.
|
|
|
|
``table.oe_list_content``
|
|
|
|
The root table for the listview, accessory components may be
|
|
generated or added outside this section, this is the list view
|
|
"proper".
|
|
|
|
``.oe_list_buttons``
|
|
|
|
The action buttons array for the list view, with its sub-elements
|
|
|
|
``.oe_list_add``
|
|
|
|
The default "Create"/"Add" button of the list view
|
|
|
|
``.oe_alternative``
|
|
|
|
The "alternative choice" for the list view, by default text
|
|
along the lines of "or import" with a link.
|
|
|
|
``.oe_list_field_cell``
|
|
|
|
The cell (``td``) for a given field of the list view, cells which
|
|
are *not* fields (e.g. name of a group, or number of items in a
|
|
group) will not have this class. The field cell can be further
|
|
specified:
|
|
|
|
``.oe_number``
|
|
|
|
Numeric cell types (integer and float)
|
|
|
|
``.oe_button``
|
|
|
|
Action button (``button`` tag in the view) inside the cell
|
|
|
|
``.o_readonly``
|
|
|
|
Readonly field cell
|
|
|
|
``.oe_list_field_$type``
|
|
|
|
Additional class for the precise type of the cell, ``$type``
|
|
is the field's @widget if there is one, otherwise it's the
|
|
field's type.
|
|
|
|
``.oe_list_record_selector``
|
|
|
|
Selector cells
|
|
|
|
Editable list view
|
|
++++++++++++++++++
|
|
|
|
The editable list view module adds a few supplementary style hook
|
|
classes, for edition situations:
|
|
|
|
``.o_list_editable``
|
|
|
|
Added to the ``.oe_list`` when the list is editable (however that
|
|
was done). The class may be removed on-the-fly if the list becomes
|
|
non-editable.
|
|
|
|
``.oe_editing``
|
|
|
|
Added to both ``.oe_list`` and ``.oe_list_button`` (as the
|
|
buttons may be outside of the list view) when a row of the list is
|
|
currently being edited.
|
|
|
|
``tr.oe_edition``
|
|
|
|
Class set on the row being edited itself. Note that the edition
|
|
form is *not* contained within the row, this allows for styling or
|
|
modifying the row while it's being edited separately. Mostly for
|
|
fields which can not be edited (e.g. read-only fields).
|
|
|
|
Columns display customization
|
|
-----------------------------
|
|
|
|
The list view provides a registry to
|
|
:js:class:`openerp.web.list.Column` objects allowing for the
|
|
customization of a column's display (e.g. so that a binary field is
|
|
rendered as a link to the binary file directly in the list view).
|
|
|
|
The registry is ``instance.web.list.columns``, the keys are of the
|
|
form ``tag.type`` where ``tag`` can be ``field`` or ``button``, and
|
|
``type`` can be either the field's type or the field's ``@widget`` (in
|
|
the view).
|
|
|
|
Most of the time, you'll want to define a ``tag.widget`` key
|
|
(e.g. ``field.progressbar``).
|
|
|
|
.. js:class:: openerp.web.list.Column(id, tag, attrs)
|
|
|
|
.. js:function:: openerp.web.list.Column.format(record_data, options)
|
|
|
|
Top-level formatting method, returns an empty string if the
|
|
column is invisible (unless the ``process_modifiers=false``
|
|
option is provided); returns ``options.value_if_empty`` or an
|
|
empty string if there is no value in the record for the
|
|
column.
|
|
|
|
Otherwise calls :js:func:`~openerp.web.list.Column._format`
|
|
and returns its result.
|
|
|
|
This method only needs to be overridden if the column has no
|
|
concept of values (and needs to bypass that check), for a
|
|
button for instance.
|
|
|
|
Otherwise, custom columns should generally override
|
|
:js:func:`~openerp.web.list.Column._format` instead.
|
|
|
|
:returns: String
|
|
|
|
.. js:function:: openerp.web.list.Column._format(record_data, options)
|
|
|
|
Never called directly, called if the column is visible and has
|
|
a value.
|
|
|
|
The default implementation calls
|
|
:js:func:`~openerp.web.format_value` and htmlescapes the
|
|
result (via ``_.escape``).
|
|
|
|
Note that the implementation of
|
|
:js:func:`~openerp.web.list.Column._format` *must* escape the
|
|
data provided to it, its output will *not* be escaped by
|
|
:js:func:`~openerp.web.list.Column.format`.
|
|
|
|
:returns: String
|
|
|
|
Editable list view
|
|
------------------
|
|
|
|
List view edition is an extension to the base listview providing the
|
|
capability of inline record edition by delegating to an embedded form
|
|
view.
|
|
|
|
Editability status
|
|
++++++++++++++++++
|
|
|
|
The editability status of a list view can be queried through the
|
|
:js:func:`~openerp.web.ListView.editable` method, will return a falsy
|
|
value if the listview is not currently editable.
|
|
|
|
The editability status is based on three flags:
|
|
|
|
``tree/@editable``
|
|
|
|
If present, can be either ``"top"`` or ``"bottom"``. Either will
|
|
make the list view editable, with new records being respectively
|
|
created at the top or at the bottom of the view.
|
|
|
|
``context.set_editable``
|
|
|
|
Boolean flag extracted from a search context (during the
|
|
:js:func:`~openerp.web.ListView.do_search`` handler), ``true``
|
|
will make the view editable (from the top), ``false`` or the
|
|
absence of the flag is a noop.
|
|
|
|
``defaults.editable``
|
|
|
|
Like ``tree/@editable``, one of absent (``null``)), ``"top"`` or
|
|
``"bottom"``, fallback for the list view if none of the previous
|
|
two flags are set.
|
|
|
|
These three flags can only *make* a listview editable, they can *not*
|
|
override a previously set flag. To do that, a listview user should
|
|
instead cancel :ref:`the edit:before event <listview-edit-before>`.
|
|
|
|
The editable list view module adds a number of methods to the list
|
|
view, on top of implementing the :js:class:`EditorDelegate` protocol:
|
|
|
|
Interaction Methods
|
|
+++++++++++++++++++
|
|
|
|
.. js:function:: openerp.web.ListView.ensure_saved
|
|
|
|
Attempts to resolve the pending edition, if any, by saving the
|
|
edited row's current state.
|
|
|
|
:returns: delegate resolving to all editions having been saved, or
|
|
rejected if a pending edition could not be saved
|
|
(e.g. validation failure)
|
|
|
|
.. js:function:: openerp.web.ListView.start_edition([record][, options])
|
|
|
|
Starts editing the provided record inline, through an overlay form
|
|
view of editable fields in the record.
|
|
|
|
If no record is provided, creates a new one according to the
|
|
editability configuration of the list view.
|
|
|
|
This method resolves any pending edition when invoked, before
|
|
starting a new edition.
|
|
|
|
:param record: record to edit, or null to create a new record
|
|
:type record: :js:class:`~openerp.web.list.Record`
|
|
:param EditOptions options:
|
|
:returns: delegate to the form used for the edition
|
|
|
|
.. js:function:: openerp.web.ListView.save_edition
|
|
|
|
Resolves the pending edition.
|
|
|
|
:returns: delegate to the save being completed, resolves to an
|
|
object with two attributes ``created`` (flag indicating
|
|
whether the saved record was just created or was
|
|
updated) and ``record`` the reloaded record having been
|
|
edited.
|
|
|
|
.. js:function:: openerp.web.ListView.cancel_edition([force=false])
|
|
|
|
Cancels pending edition, cleans up the list view in case of
|
|
creation (removes the empty record being created).
|
|
|
|
:param Boolean force: doesn't check if the user has added any
|
|
data, discards the edition unconditionally
|
|
|
|
Utility Methods
|
|
+++++++++++++++
|
|
|
|
.. js:function:: openerp.web.ListView.get_cells_for(row)
|
|
|
|
Extracts the cells from a listview row, and puts them in a
|
|
{fieldname: cell} mapping for analysis and manipulation.
|
|
|
|
:param jQuery row:
|
|
:rtype: Object
|
|
|
|
.. js:function:: openerp.web.ListView.with_event(event_name, event, action[, args][, trigger_params])
|
|
|
|
Executes ``action`` in the context of the view's editor,
|
|
bracketing it with cancellable event signals.
|
|
|
|
:param String event_name: base name for the bracketing event, will
|
|
be postfixed by ``:before`` and
|
|
``:after`` before being called
|
|
(respectively before and after
|
|
``action`` is executed)
|
|
:param Object event: object passed to the ``:before`` event
|
|
handlers.
|
|
:param Function action: function called with the view's editor as
|
|
its ``this``. May return a deferred.
|
|
:param Array args: arguments passed to ``action``
|
|
:param Array trigger_params: arguments passed to the ``:after``
|
|
event handler alongside the results
|
|
of ``action``
|
|
|
|
Behavioral Customizations
|
|
+++++++++++++++++++++++++
|
|
|
|
.. js:function:: openerp.web.ListView.handle_onwrite(record)
|
|
|
|
Implements the handling of the ``onwrite`` listview attribute:
|
|
calls the RPC methods specified by ``@onwrite``, and if that
|
|
method returns an array of ids loads or reloads the records
|
|
corresponding to those ids.
|
|
|
|
:param record: record being written having triggered the
|
|
``onwrite`` callback
|
|
:type record: openerp.web.list.Record
|
|
:returns: deferred to all reloadings being done
|
|
|
|
Events
|
|
++++++
|
|
|
|
For simpler interactions by/with external users of the listview, the
|
|
view provides a number of dedicated events to its lifecycle.
|
|
|
|
.. note:: if an event is defined as *cancellable*, it means its first
|
|
parameter is an object on which the ``cancel`` attribute can
|
|
be set. If the ``cancel`` attribute is set, the view will
|
|
abort its current behavior as soon as possible, and rollback
|
|
any state modification.
|
|
|
|
Generally speaking, an event should only be cancelled (by
|
|
setting the ``cancel`` flag to ``true``), uncancelling an
|
|
event is undefined as event handlers are executed on a
|
|
first-come-first-serve basis and later handlers may
|
|
re-cancel an uncancelled event.
|
|
|
|
.. _listview-edit-before:
|
|
|
|
``edit:before`` *cancellable*
|
|
|
|
Invoked before the list view starts editing a record.
|
|
|
|
Provided with an event object with a single property ``record``,
|
|
holding the attributes of the record being edited (``record`` is
|
|
empty *but not null* for a new record)
|
|
|
|
``edit:after``
|
|
|
|
Invoked after the list view has gone into an edition state,
|
|
provided with the attributes of the record being edited (see
|
|
``edit:before``) as first parameter and the form used for the
|
|
edition as second parameter.
|
|
|
|
``save:before`` *cancellable*
|
|
|
|
Invoked right before saving a pending edition, provided with an
|
|
event object holding the listview's editor (``editor``) and the
|
|
edition form (``form``)
|
|
|
|
``save:after``
|
|
|
|
Invoked after a save has been completed
|
|
|
|
``cancel:before`` *cancellable*
|
|
|
|
Invoked before cancelling a pending edition, provided with the
|
|
same information as ``save:before``.
|
|
|
|
``cancel:after``
|
|
|
|
Invoked after a pending edition has been cancelled.
|
|
|
|
DOM events
|
|
++++++++++
|
|
|
|
The list view has grown hooks for the ``keyup`` event on its edition
|
|
form (during edition): any such event bubbling out of the edition form
|
|
will be forwarded to a method ``keyup_EVENTNAME``, where ``EVENTNAME``
|
|
is the name of the key in ``$.ui.keyCode``.
|
|
|
|
The method will also get the event object (originally passed to the
|
|
``keyup`` handler) as its sole parameter.
|
|
|
|
The base editable list view has handlers for the ``ENTER`` and
|
|
``ESCAPE`` keys.
|
|
|
|
Editor
|
|
------
|
|
|
|
The list-edition modules does not generally interact with the embedded
|
|
formview, delegating instead to its
|
|
:js:class:`~openerp.web.list.Editor`.
|
|
|
|
.. js:class:: openerp.web.list.Editor(parent[, options])
|
|
|
|
The editor object provides a more convenient interface to form
|
|
views, and simplifies the usage of form views for semi-arbitrary
|
|
edition of stuff.
|
|
|
|
However, the editor does *not* task itself with being internally
|
|
consistent at this point: calling
|
|
e.g. :js:func:`~openerp.web.list.Editor.edit` multiple times in a
|
|
row without saving or cancelling each edit is undefined.
|
|
|
|
:param parent:
|
|
:type parent: :js:class:`~openerp.web.Widget`
|
|
:param EditorOptions options:
|
|
|
|
.. js:function:: openerp.web.list.Editor.is_editing([record_state])
|
|
|
|
Indicates whether the editor is currently in the process of
|
|
providing edition for a record.
|
|
|
|
Can be filtered by the state of the record being edited
|
|
(whether it's a record being *created* or a record being
|
|
*altered*), in which case it asserts both that an edition is
|
|
underway and that the record being edited respectively does
|
|
not yet exist in the database or already exists there.
|
|
|
|
:param record_state: state of the record being edited.
|
|
Either ``"new"`` or ``"edit"``.
|
|
:type record_state: String
|
|
:rtype: Boolean
|
|
|
|
.. js:function:: openerp.web.list.Editor.edit(record, configureField[, options])
|
|
|
|
Loads the provided record into the internal form view and
|
|
displays the form view.
|
|
|
|
Will also attempt to focus the first visible field of the form
|
|
view.
|
|
|
|
:param Object record: record to load into the form view
|
|
(key:value mapping similar to the result
|
|
of a ``read``)
|
|
:param configureField: function called with each field of the
|
|
form view right after the form is
|
|
displayed, lets whoever called this
|
|
method do some last-minute
|
|
configuration of form fields.
|
|
:type configureField: Function<String, openerp.web.form.Field>
|
|
:param EditOptions options:
|
|
:returns: jQuery delegate to the form object
|
|
|
|
.. js:function:: openerp.web.list.Editor.save
|
|
|
|
Attempts to save the internal form, then hide it
|
|
|
|
:returns: delegate to the record under edition (with ``id``
|
|
added for a creation). The record is not updated
|
|
from when it was passed in, aside from the ``id``
|
|
attribute.
|
|
|
|
.. js:function:: openerp.web.list.Editor.cancel([force=false])
|
|
|
|
Attemps to cancel the edition of the internal form, then hide
|
|
the form
|
|
|
|
:param Boolean force: unconditionally cancels the edition of
|
|
the internal form, even if the user has
|
|
already entered data in it.
|
|
:returns: delegate to the record under edition
|
|
|
|
.. js:class:: EditorOptions
|
|
|
|
.. js:attribute:: EditorOptions.formView
|
|
|
|
Form view (sub)-class to instantiate and delegate edition to.
|
|
|
|
By default, :js:class:`~openerp.web.FormView`
|
|
|
|
.. js:attribute:: EditorOptions.delegate
|
|
|
|
Object used to get various bits of information about how to
|
|
display stuff.
|
|
|
|
By default, uses the editor's parent widget. See
|
|
:js:class:`EditorDelegate` for the methods and attributes to
|
|
provide.
|
|
|
|
.. js:class:: EditorDelegate
|
|
|
|
Informal protocol defining the methods and attributes expected of
|
|
the :js:class:`~openerp.web.list.Editor`'s delegate.
|
|
|
|
.. js:attribute:: EditorDelegate.dataset
|
|
|
|
The dataset passed to the form view to synchronize the form
|
|
view and the outer widget.
|
|
|
|
.. js:function:: EditorDelegate.edition_view(editor)
|
|
|
|
Called by the :js:class:`~openerp.web.list.Editor` object to
|
|
get a form view (JSON) to pass along to the form view it
|
|
created.
|
|
|
|
The result should be a valid form view, see :doc:`Form Notes
|
|
<form_view>` for various peculiarities of the form view
|
|
format.
|
|
|
|
:param editor: editor object asking for the view
|
|
:type editor: :js:class:`~openerp.web.list.Editor`
|
|
:returns: form view
|
|
:rtype: Object
|
|
|
|
.. js:function:: EditorDelegate.prepends_on_create
|
|
|
|
By default, the :js:class:`~openerp.web.list.Editor` will
|
|
append the ids of newly created records to the
|
|
:js:attr:`EditorDelegate.dataset`. If this method returns
|
|
``true``, it will prepend these ids instead.
|
|
|
|
:returns: whether new records should be prepended to the
|
|
dataset (instead of appended)
|
|
:rtype: Boolean
|
|
|
|
|
|
.. js:class:: EditOptions
|
|
|
|
Options object optionally passed into a method starting an edition
|
|
to configure its setup and behavior
|
|
|
|
.. js:attribute:: focus_field
|
|
|
|
Name of the field to set focus on after setting up the edition
|
|
of the record.
|
|
|
|
If this option is not provided, or the requested field can not
|
|
be focused (invisible, readonly or not in the view), the first
|
|
visible non-readonly field is focused.
|
|
|
|
Changes from 6.1
|
|
----------------
|
|
|
|
* The editable listview behavior has been rewritten pretty much from
|
|
scratch, any code touching on editability will have to be modified
|
|
|
|
* The overloading of :js:class:`~openerp.web.ListView.Groups` and
|
|
:js:class:`~openerp.web.ListView.List` for editability has been
|
|
drastically simplified, and most of the behavior has been moved to
|
|
the list view itself. Only
|
|
:js:func:`~openerp.web.ListView.List.row_clicked` is still
|
|
overridden.
|
|
|
|
* A new method ``get_row_for(record) -> jQuery(tr) | null`` has been
|
|
added to both ListView.List and ListView.Group, it can be called
|
|
from the list view to get the table row matching a record (if such
|
|
a row exists).
|
|
|
|
* :js:func:`~openerp.web.ListView.do_button_action`'s core behavior
|
|
has been split away to
|
|
:js:func:`~openerp.web.ListView.handle_button`. This allows bypassing
|
|
overrides of :js:func:`~openerp.web.ListView.do_button_action` in a
|
|
parent class.
|
|
|
|
Ideally, :js:func:`~openerp.web.ListView.handle_button` should not be
|
|
overridden.
|
|
|
|
* Modifiers handling has been improved (all modifiers information
|
|
should now be available through :js:func:`~Column.modifiers_for`,
|
|
not just ``invisible``)
|
|
|
|
* Changed some handling of the list view's record: a record may now
|
|
have no id, and the listview will handle that correctly (for new
|
|
records being created) as well as correctly handle the ``id`` being
|
|
set.
|
|
|
|
* Extended the internal collections structure of the list view with
|
|
`#find`_, `#succ`_ and `#pred`_.
|
|
|
|
.. _#find: http://underscorejs.org/#find
|
|
|
|
.. _#succ: http://hackage.haskell.org/packages/archive/base/latest/doc/html/Prelude.html#v:succ
|
|
|
|
.. _#pred: http://hackage.haskell.org/packages/archive/base/latest/doc/html/Prelude.html#v:pred
|
