In such case when you need to show the value of a field from a relational model to the current model you can do that by defining a new related field. To do that you need in the field definition to define attribute related with value sequence of field names. By default, the value of the related field is not stored in the database. If you want to store it you need to define attribute store with value True.
Below you can find an example of using a related field in the ContactPartner model in order to show if it is a free member on its views.
from openerp import models, fields
class PartnerContact(models.Model):
_name = 'partner.contact'
user_id = fields.Many2one('res.users', 'User')
free_member = fields.Boolean(related='user_id.free_member')
hi , have a problem with my related field , i have two classes : nomenclature and projet_ligne i want to get the value of ‘ sous’ on ‘eta’ so there s my code
class nomenclature(models.Model):
_name = ‘nomenclature’
name = fields.Char(‘Nom de la nomenclature’,required=True)
quantite = fields.Integer(‘Quantité’,required=True)
produit=fields.Many2one(‘product.product’)
sous= fields.Boolean(‘sous’)
class projet_ligne(models.Model):
_name = ‘projet.ligne’
#name = fields.Char(‘nom du sous essaie’,required=True)
nomenclature=fields.Many2one(‘nomenclature’,required=True)
responsable=fields.Many2one(‘res.users’,)
projet = fields.Many2one(‘projet’,required=True)
date= fields.Date()
etat=fields.Boolean(‘Achevé?’)
reference= fields.Char(‘Réference’)
nature= fields.Char(‘Nature’)
dateprelevement= fields.Date()
lieuprelevement= fields.Char(‘lieu’)
etatvalider= fields.Boolean(‘Validé’)
eta= fields.Boolean(related=’nomenclature.sous’)
It doesn t work :/
Hi Najlae,
What is the error that you are getting?
You need to put apostrophe to user_id.free_member
free_member = fields.Boolean(related=’user_id.free_member’)
so you don’t get an error
Regards
Thanks Betone for the correction, I have missed it somehow, sorry for that.
Correction is made.
you need to input the name of the module what you want to do it many2one relation
For a many2one field, you would need to define the relation as usually and additionally need to provide “related” attribute.
