class Target(models.Model):
_name = "target"
product_ids = fields.Many2many('product.product', string="Products")
targetpoints_ids = fields.One2many('target.points', 'target_id', string="Points")

class TargetPoints(models.Model):
_name = "target.points"
target_id = fields.Many2one('target', required=True, index=True)
product_id = fields.Many2one('product.product', string="Product")
points = fields.Integer(string="Amount of points")

Every Target has 0, 1 or more products linked (product_ids). On the formview of Target I am also displaying the targetpoints_ids records.
- So far so good -

However I want to limit the product_id of TargetPoints to the product_ids that are previously linked to target.I thought it would be as simple as adding something like the below to the product_id field.

domain="[('id','in', target_id.product_ids.ids)]"

However nothing seems to work.
I have tried to use:
- Related fields to get the information of the other model like that (no difference)
- Put the domain filter on the view instead of in the model (no difference)
- Onchange method on product_ids that returns a domain dictionary (but can you change the domain of a field in a different model with this?)

If I literally use a list of ids [1500, 1501, 1502] instead of the .ids in my domain filter my attempts seem to do exactly what I want.

I am using Odoo 10. I am not sure if my question has to do with the dicussion on this link https://github.com/odoo/odoo/issues/16072

Any help is really appreciated.

Hi,

Other than returning domain in onchange method, you can use the web domain field module from oca for the same:  Web Domain Field


See this: Return Dynamic Domain For Field In Odoo


How to use:

.. code-block:: xml

   <field name="product_id_domain" invisible="1"/>
   <field name="product_id" domain="product_id_domain"/>


.. code-block:: python

   product_id_domain = fields.Char(
       compute="_compute_product_id_domain",
       readonly=True,
       store=False,
   )

   @api.multi
   @api.depends('name')
   def _compute_product_id_domain(self):
       for rec in self:
           rec.product_id_domain = json.dumps(
               [('type', '=', 'product'), ('name', 'like', rec.name)]
           )

The save button function from the application menu in recruitment is not the same with the save button function on the button from a form link to the applications menu.
