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:

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.
**Table of contents**
.. contents::
:local:
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.
* Support extra invisible fields inside each cell.
