Web Domain Field

Beta License: AGPL-3 OCA/web Translate me on Weblate Try me on Runboat

Warning

This module is deprecated. If you want to use this functionality you can assign a unserialised domain to a fields.Binary, example

This technical addon allows developers to specify a field domain in a view using the value of another field in that view, rather than as a static XML attribute.

Table of contents

Usage

When you define a view you can specify on the relational fields a domain attribute. This attribute is evaluated as filter to apply when displaying existing records for selection.

<field name="product_id" domain="[('type','=','product')]"/>

The value provided for the domain attribute must be a string representing a valid Odoo domain. This string is evaluated on the client side in a restricted context where we can reference as right operand the values of fields present into the form and a limited set of functions.

In this context it's hard to build complex domain and we are facing to some limitations as:

  • The syntax to include in your domain a criteria involving values from a x2many field is complex.
  • The right side of domain in case of x2many can involve huge amount of ids (performance problem).
  • Domains computed by an onchange on an other field are not recomputed when you modify the form and don't modify the field triggering the onchange.
  • It's not possible to extend an existing domain. You must completely redefine the domain in your specialized addon
  • etc...

In order to mitigate these limitations this new addon allows you to use the value of a field as domain of an other field in the xml definition of your view.

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

The field used as domain must provide the domain as a JSON encoded string.

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

@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)]
        )

Note

You do not actually need this module to craft a dynamic domain. Odoo comes with its own py.js web library to parse expressions such as domains. py.js supports more complex expressions than just static lists.

Here is an example of a conditional domain based on the value of another field:

(order_id or partner_id) and [('id', 'in', allowed_picking_ids)]
or [('state', '=', 'done'), ('picking_type_id.code', '=', 'outgoing')]

For OCA modules, this method is preferred over adding this module as an additional dependency.
