Hello everyone,

I am working with Odoo 12 and having a problem on setting a domain on a form view for the account.payments model.

What I need to do is to show only users (partner_id) that has the field "parent_id" = False under partner_id field.

I have successfully tried on the account.invoice and changed the xml for the form view to:

       <record id="mymodule_form_view_account_invoice" model="ir.ui.view">
           <field name="name">Account Invoice Hide Children Partners</field>
           <field name="model">account.invoice</field>
           <field name="inherit_id" ref="account.invoice_form"/>
           <field name="arch" type="xml">
                <xpath expr="//field[@name='partner_id']" position="replace">
                       <field string="Customer" name="partner_id" widget="res_partner_many2one" context="{'search_default_customer':1, 'show_address': 1, 'default_is_company': True, 'show_vat': True}" options="{"always_reload": True, "no_quick_create": True}" domain="[('customer', '=', True),('parent_id', '=', False)]" required="1"/>
                </xpath>
          </field>
      </record>

I was able to hide partners with "parent_id" using the domain:

       domain="[('customer', '=', True),('parent_id', '=', False)]" required="1"

Tried to do the same for the account.payment model and was unable to achieve what I want.

I can see that on the account.payment form view there's a "partner_id" field and tried to:

       <field name="partner_id" domain="[('parent_id', '=', False)]" attrs="{'required': [('state', '=', 'draft'), ('payment_type', 'in', ('inbound', 'outbound'))], 'invisible': [('payment_type', 'not in', ('inbound', 'outbound'))], 'readonly': [('state', '!=', 'draft')]}" context="{'default_is_company': True, 'default_supplier': payment_type == 'outbound', 'default_customer': payment_type == 'inbound'}"/>

...and it does not work.

Using debug mode with mouse over the field, I can see that the domain is applied but it simple does not work.

Then, I have noticed that, in fact there is no "partner_id" on the account.payment form. This field in on the "account.abstract.payment" abstract model that is shared among models which allows to register payments.

Since I cannot find any related xml id for this model for changing the partner_id default values, I have tried to directly (for testing purposes) change the field definition to:

      _name = "account.abstract.payment"
      ....
      ....
      partner_id = fields.Many2one('res.partner', string='Partner', domain=lambda self: [("parent_id", "=", "False")])

Even adding the domain above on the field definition, I am unable to achieve what I need.

Can anyone help me please?

Thank you all in advance

Best regards

PM
