2D matrix for x2many fields
===========================
This module allows to show an x2many field with 3-tuples
($x_value, $y_value, $value) in a table
+-----------+-------------+-------------+
| | $x_value1 | $x_value2 |
+===========+=============+=============+
| $y_value1 | $value(1/1) | $value(2/1) |
+-----------+-------------+-------------+
| $y_value2 | $value(1/2) | $value(2/2) |
+-----------+-------------+-------------+
where `value(n/n)` is editable.
An example use case would be: Select some projects and some employees so that
a manager can easily fill in the planned_hours for one task per employee. The
result could look like this:
.. image:: /web_widget_x2many_2d_matrix/static/description/screenshot.png
:alt: Screenshot
The beauty of this is that you have an arbitrary amount of columns with this
widget, trying to get this in standard x2many lists involves some quite ugly
hacks.
Usage
=====
Use this widget by saying::
<field name="my_field" widget="x2many_2d_matrix" />
This assumes that my_field refers to a model with the fields `x`, `y` and
`value`. If your fields are named differently, pass the correct names as
attributes:
.. code-block:: xml
<field name="my_field" widget="x2many_2d_matrix" field_x_axis="my_field1" field_y_axis="my_field2" field_value="my_field3">
<tree>
<field name="my_field"/>
<field name="my_field1"/>
<field name="my_field2"/>
<field name="my_field3"/>
</tree>
</field>
You can pass the following parameters:
field_x_axis
The field that indicates the x value of a point
field_y_axis
The field that indicates the y value of a point
field_label_x_axis
Use another field to display in the table header
field_label_y_axis
Use another field to display in the table header
field_value
Show this field as value
show_row_totals
If field_value is a numeric field, it indicates if you want to calculate
row totals. True by default
show_column_totals
If field_value is a numeric field, it indicates if you want to calculate
column totals. True by default

Example
=======
You need a data structure already filled with values. Let's assume we want to
use this widget in a wizard that lets the user fill in planned hours for one
task per project per user. In this case, we can use ``project.task`` as our
data model and point to it from our wizard. The crucial part is that we fill
the field in the default function:
.. code-block:: python
from odoo import fields, models
class MyWizard(models.TransientModel):
_name = 'my.wizard'
def _default_task_ids(self):
# your list of project should come from the context, some selection
# in a previous wizard or wherever else
projects = self.env['project.project'].browse([1, 2, 3])
# same with users
users = self.env['res.users'].browse([1, 2, 3])
return [
(0, 0, {
'name': 'Sample task name',
'project_id': p.id,
'user_id': u.id,
'planned_hours': 0,
'message_needaction': False,
'date_deadline': fields.Date.today(),
})
# if the project doesn't have a task for the user,
# create a new one
if not p.task_ids.filtered(lambda x: x.user_id == u) else
# otherwise, return the task
(4, p.task_ids.filtered(lambda x: x.user_id == u)[0].id)
for p in projects
for u in users
]
task_ids = fields.Many2many('project.task', default=_default_task_ids)
Now in our wizard, we can use:
.. code-block:: xml
<field name="task_ids" widget="x2many_2d_matrix" field_x_axis="project_id" field_y_axis="user_id" field_value="planned_hours">
<tree>
<field name="task_ids"/>
<field name="project_id"/>
<field name="user_id"/>
<field name="planned_hours"/>
</tree>
</field>
Known issues / Roadmap
======================
* Support extra attributes on each field cell via `field_extra_attrs` param.
We could set a cell as not editable, required or readonly for instance.
The `readonly` case will also give the ability
to click on m2o to open related records.
* Support limit total records in the matrix. Ref: https://github.com/OCA/web/issues/901
* Support cell traversal through keyboard arrows.
* Entering the widget from behind by pressing ``Shift+TAB`` in your keyboard
will enter into the 1st cell until https://github.com/odoo/odoo/pull/26490
is merged.
Bug Tracker
===========
Bugs are tracked on `GitHub Issues
<https://github.com/OCA/web/issues>`_. In case of trouble, please
check there if your issue has already been reported. If you spotted it first,
help us smash it by providing a detailed and welcomed feedback.
