如何在odoo中使用python设置域

Question

Is it possible to set domain on the python side without putting it in view? I tried to set the domain in the customer field (sale order) based on branch in the Customer menu/template

I have tried this but why it doesn't work?

@api.onchange('partner_id')
def _onchange_cust_domain(self):
    for rec in self:
        if self.branch_id.id:
            cust_list = rec.partner_id.branch_id.id
        return {'domain' : {'partner_id' : [('branch_id', '=', cust_list)]}}

Answer 1

I think your problem is that you are making a domain for a field partner_id, but in the onchange method of the same field. It makes no sense to me. So if you put a Customer with branch X, then you can only search customers of branch X for that sale_order (if that domain do the job). I dont know what are you trying to do exactly, but i think than changing a domain in the same field you are changing the value it is no possible.

Your code would be correct if that domain applies to another field.

This is a working exaple. Notice that onchange field method and field to apply domain are diferent:

    @api.onchange('operating_unit_id')
    def _applicants_onchange(self):
        if self.operating_unit_id:
            return {'domain': {'applicant_id': [('default_operating_unit_id', '=', self.operating_unit_id.id)]}}
        return {}

Answer 2

To set the partner_id domain when the branch_id field value changes, use the following onchange function:

Example:

@api.onchange('branch_id')
def onchange_branch_id(self):
    if self.branch_id:
        return {'domain': {'partner_id': [('branch_id', '=', self.branch_id.id)]}}

Odoo sets by default the following domain from the python code:

['|', ('company_id', '=', False), ('company_id', '=', company_id)]

Answer 3

Returning a domain using onchange method has been deprecated in Odoo 14.

I'm using this OCA module to filter field depend on another field.
