Hello I am trying to get a one2one relationship to work. Here are my
classes:
*class Formulario*(ModelSQL,ModelView):
'Formulario'
_name = 'cefiro.formulario'
_description = __doc__
formVivTrabajo =
fields.One2One('cefiro.formvivtrabajo','formularioid','formvivtrabajoid','Vivienda
y Trabajo', required=True)
Formulario()
*class Formvivtrabtarget*(ModelSQL,ModelView):
'Formvivtrabtarget'
_name = 'cefiro.formvivtrabtarget.target'
_description = __doc__
tipoVivienda = fields.Selection([('casa','La casa'),('calle','La
calle'),('inst',u'Institución protectora'),('car','Privado de
libertad')],'Vive en',required=True)
Formvivtrabtarget()
*class Formviviendatrabajo*(ModelSQL,ModelView):
'Formvivtrabajo'
_name = 'cefiro.formvivtrabajo'
_description = __doc__
formvivtrabajoid = fields.Many2One('cefiro.formvivtrabtarget.target',
'Formvivtrabtarget')
formularioid = fields.Many2One('cefiro.formulario', 'Formulario')
def __init__(self):
super(Formviviendatrabajo, self).__init__()
self._sql_constraints += [
('origin_unique', 'UNIQUE(formularioid)','Origin must be
unique'),
('target_unique', 'UNIQUE(formvivtrabajoid)','Target must be
unique'),
]
Formviviendatrabajo()
You can see that I already have formvivtrabjoid as a Formviviendatrabajo's
field but I am getting the following error when saving it:
Traceback (most recent call last):
