Hi i'm totally new in python, hope i will get help from experience person. Is possible to get data one model to another in a model using foreign key.... I tried this way but can getting result ....

    class A(models.Model):

        _inherit = 'project.task'

        field_a = fields.Char(string='field_a')

        field_b = fields.Char('field_b')

    class B(models.Model):

        # _inherit = 'project.task'

        field_a = fields.Char(string='field_a class B')

        field_b2 = fields.Char(string='field_b2')

    class C(models.Model):

        # _inherit = 'project.task'

        field_a = fields.Char('field_a class C')

        field_c = fields.Char('field_c')
