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:

: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.
Note: The order of axis values depends on their order in the matrix you provide.
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::
<field name="my_field" widget="x2many_2d_matrix" field_x_axis="my_field1" field_y_axis="my_field2" field_value="my_field3" />
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
x_axis_clickable
It indicates if the X axis allows to be clicked for navigating to the field
(if it's a many2one field). True by default
y_axis_clickable
It indicates if the Y axis allows to be clicked for navigating to the field
(if it's a many2one field). True by default
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, calculate row totals
show_column_totals
If field_value is a numeric field, calculate column totals
field_att_<name>
Declare as many options prefixed with this string as you need for binding
a field value with an HTML node attribute (disabled, class, style...)
called as the `<name>` passed in the option.

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::
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, {'project_id': p.id, 'user_id': u.id, 'planned_hours': 0})
# 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" />
Note that all values in the matrix must exist, so you need to create them
previously if not present, but you can control visually the editability of
the fields in the matrix through `field_att_disabled` option with a control
field.
Known issues / Roadmap
======================
* it would be worth trying to instantiate the proper field widget and let it render the input
