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:


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


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:

<field name="my_field" widget="x2many_2d_matrix" field_x_axis="my_field1" field_y_axis="my_field2" field_value="my_field3">
        <field name="my_field"/>
        <field name="my_field1"/>
        <field name="my_field2"/>
        <field name="my_field3"/>

You can pass the following parameters:

The field that indicates the x value of a point
The field that indicates the y value of a point
Use another field to display in the table header
Use another field to display in the table header
Show this field as value
If field_value is a numeric field, it indicates if you want to calculate row totals. True by default
If field_value is a numeric field, it indicates if you want to calculate column totals. True by default


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:

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:

<field name="task_ids" widget="x2many_2d_matrix" field_x_axis="project_id" field_y_axis="user_id" field_value="planned_hours">
        <field name="task_ids"/>
        <field name="project_id"/>
        <field name="user_id"/>
        <field name="planned_hours"/>

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.
  • Support kanban mode. Current behaviour forces list mode.

Changelog (2018-12-07)

  • [FIX] Cells are unable to render property. (#1126) (2018-11-20)

  • [12.0][MIG] web_widget_x2many_2d_matrix (#1101)
