2D matrix for x2many fields x2many字段的2D矩阵


此模块允许在表中显示带有3元组($ x_value,$ y_value,$ value)的x2many字段 

This module allows to show an x2many field with 3-tuples ($x_value, $y_value, $value) in a table


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.


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 xy 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"/>
