I need to create a One2Many field in Odoo, but using the same model where the field is created. For example.

class WindowForm(models.Model):

        _name= 'window.form'

        doors = fields.One2Many('window.form')

As you can see the One2Many field has the same model of the class where it is declared.

I know that the above declaration is not correct, but that is exactly my doubt. When you define a One2Many field you have to create Many2One field in the other model. So, how can i declare the One2Many?

Thanks in advanced.
