I have 3 models:

seniat_form_86:

'line_ids':fields.one2many('seniat.form.86.lines','line_id','Tax lines',readonly=True, states={'draft':[('readonly',False)]}),
'invoice_ids':fields.one2many('account.invoice','num_import_form_id','Related invoices',readonly=True),

seniat_form_86_lines:

'line_id':fields.many2one('seniat.form.86', 'Line', required=True, ondelete='cascade'),
'line_vat_ids':fields.one2many('seniat.form_86.lines.vat','line_vat_id','Vat lines',attrs="{'readonly':[('vat_detail','=',True)],'required':[('vat_detail','=',True)]}"),

seniat_form_86_lines_vat:

'line_vat_id':fields.many2one('seniat.form.86.lines', 'Vat line', required=True, ondelete='cascade'),
'invoice_id': fields.many2one('account.invoice', 'Invoice Reference', ondelete='restrict', select=True, required=True),

...

as you can see the 3 models are "master-detail" interrelated.

I need to set a domain for seniat_form_86_lines_vat.invoice_id like this:

domain="[('id','in',line_vat_id.line_id.invoice_ids)]"

Error: NameError: name 'line_vat_id' is not defined if widget="selection" in view

I want to filter seniat_form_86_lines_vat.invoice_id with only invoices listed in seniat_form_86.invoice_ids.

Note: Server 6.0

Note 2: I also try with:

domain="[('id','in',parent.parent.invoice_ids)]"
domain="[('id','in',parent.line_id.invoice_ids)]"
domain="[('id','in',parent.invoice_ids)]"

Thanks.

Hi, Mohammad thanks for your fast answer but when I try to implement it I note this:

The on_change method is never called

view:

<field name="line_vat_id" invisible="1" on_change="on_change_line_vat_id(line_vat_id)"/>

Full view

   <record model="ir.ui.view" id="view_seniat_form_86_form">

model:

def on_change_line_vat_id(self, cr, uid, ids, line_vat_id):
    '''
    Create a domain to filter invoice_id for invoices listed in seniat_form_86.invoice_ids only
    '''
    res = {}
    if line_vat_id:
        line_obj = self.pool.get('seniat.form.86.lines')
        invoices = [i.id for i in line_obj.browse(cr, uid, line_vat_id).line_id.invoice_ids]
        res = {'domain': {'invoice_id': [('id','in',invoices)]}}
    return res

The method on_change_line_vat_id only is called when I make the field visible and change it manually. How I can set this domain in new or edited records?

Thanks.

In seniat_form_86_lines_vat create an on_change method for the field line_vat_id (make it invisible). The on_change method should return a domain for invoice_id using a list.

it should be something like this:

def def onchange_line_id(self, cr, uid, ids, line_vat_id)
    line_obj = self.pool['seniat.form.86.lines']
    invoices = [i.id for i in 
                line_obj.browse(cr, uid, id[0]).line_id.invoice_ids]
    return {'domain':
               {'invoice_id': [('id','in',invoices)]}
           }
