Hello, I have a module with one2many field, which installed without any problems. But when I update the module generates a KeyError for that field .

invf = env[self.comodel_name]._fields[self.inverse_name]

KeyError: 'ubicacion'

The code is: 

class res_partner(models.Model):
    _inherit = 'res.partner'
    movimientos_dispenser = fields.One2many('movimientos','ubicacion',domain=[('fecha_retiro','=',False)])

class Movimientos(models.Model):
    _name = 'movimientos'
    name = fields.Many2one('dispenser',domain=[('disponible','=',True)] , ondelete='restrict', string='Codigo de dispenser', required=True)
    ubicacion = fields.Many2one ('res.partner',domain=[('customer','=',True)], string="Ubicacion", required=True, ondelete="restrict")

Thank you for your help.

Hello my friend here is an example of two classes with Many2one and One2Many feilds:

class author(models.Model):

_name = 'mylibrary.author'

_rec_name = 'lastname'

firstname = fields.Char('FirstName', required=True)

lastname = fields.Char('LastName', required=True)

book_ids = fields.One2many('mylibrary.book','author_id','Books')

class book(models.Model):

_name = 'mylibrary.book'

title = fields.Char('Title', required=True)

genre = fields.Char('Genre', required=True)

author_id = fields.Many2one('mylibrary.author','Author',ondelete='cascade')

Here is a link you may follow to understand and get the answer.
