Hello All,

I have to two many2one type field. In field local region "Hong kong", "Kawloon" and "New Terriotories". And in another many2one fields district related to these regions. And i want that when i select a 'local region' then district avail only related to that region. 

My code is here:

Python Code:

class district_code_form(models.Model):

    _name = 'district.districe.code'

    _rec_name = 'district_mainn'


    district_mainn = fields.Char('District Value')

    district_ss = fields.One2many('district.district', 'district_id', string="District Workflow")


class district_form(models.Model):

    _name = 'district.district'

    _rec_name = 'district'


    district_id = fields.Many2one('district.district.code', string='Districts Id', ondelete='cascade', index=True, copy=False)

    district = fields.Char("District")

   

class customer_information(models.Model):

    _inherit = "res.partner"

 @api.onchange('district_table_case')

    def _onchange_district_table(self):

        if self.district_table_case:

            return {'domain': {'district_table': [('district_table_case', '=', self.district_table_case)]}}

        else:

            return {'domain': {'district_table': []}}

 district_table_case = fields.Many2one('district.districe.code')

    district_table = fields.Many2one('district.district', change_default=True, default=_onchange_district_table)
 

XML Code:


 <field name="district_table_case"/>

    <field name="district_table"/>

you will get error
Error: ValueError: Invalid field u'district_table_case' in leaf "<osv.ExtendedLeaf: (u'district_table_case', u'=', 1) on district_district (ctx: )>
Because you are trying to access the unknown field.
