Package: odoo8-addon-web-widget-x2many-2d-matrix
2D matrix for x2many fieldsThis 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)wherevalue(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.UsageUse this widget by saying:<field name="my_field" widget="x2many_2d_matrix" />This assumes that my_field refers to a model with the fieldsx,yandvalue. 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_axisThe field that indicates the x value of a pointfield_y_axisThe field that indicates the y value of a pointfield_label_x_axisUse another field to display in the table headerfield_label_y_axisUse another field to display in the table headerfield_valueShow this field as valueshow_row_totalsIf field_value is a numeric field, calculate row totalsshow_column_totalsIf field_value is a numeric field, calculate column totalsfield_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.ExampleYou 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 useproject.taskas 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 throughfield_att_disabledoption with a control
field.Known issues / Roadmapit would be worth trying to instantiate the proper field widget and let it render the inputBug TrackerBugs are tracked onGitHub Issues. In case of trouble, please
