odoo many2one作为选择字段

Question

I'm creating a module in odoo and i wanna use a many2one as a selection field, the problem is on the name of the city 'ville en francais' the dropdown works and it saves the id of the city(from database) but the name is like obj.ville,1 (it shows the name of the module,id instead of the name of the city in database)

 class obj_ghotel(osv.osv): _name = "obj.ghotel" _description = "Objet ghotel" def _get_selection(self, cr, uid, context = None): ville_obj = self.pool.get('obj.ville') ville_obj = self.env['obj.ville'] res = [] ville_ids = ville_obj.search(cr, uid, [], context = context) for g in ville_obj.browse(cr, uid, ville_ids, context = context): res.append((g.id, g.nom_ville)) return res _columns = { 'nom_hotel': fields.char( "Nom d'hotel", required=True ), 'adr_hotel': fields.char( "Addresse hotel", required=True ), 'id_ville':fields.many2one('obj.ville','ville', selection=_get_selection), #fields.integer('Id Ville', required=True ), #Foreign key references ville(id) 'id_ville':fields.many2one('ville','ville'), 'image': fields.binary( "Image" ), } 

class obj_ville(osv.osv):
    _name = "obj.ville"
    _description = "Objet ville"


    _columns = {
        'nom_ville': fields.char( "Nom Ville", required=True ),
        'id_hotel':fields.one2many('obj.ghotel','id_ville'),
    }


    _defaults = {
        'Nom Ville': "Name",
    }

Answer 1

You can use _rec_name as following:

Hotel model:

class obj_ghotel(osv.osv):
    _name = "obj.ghotel"
    _description = "Objet ghotel"
    _rec_name = 'nom_hotel'

Ville model:

class obj_ville(osv.osv):
    _name = "obj.ville"
    _description = "Objet ville"
    _rec_name = 'nom_ville'

Answer 2

This problem is when odoo don't know how to represent the record, he show you by default the name of the model and the id of the record.

How odoo know how to represent the record, this is don in name_get method defined in models.py first he looks for the value of _rec_name by default is name some i'm assuming that you don't have a field name in the model obj.ville , je pense que t'as ulilisé nom ^^.

so you need to change the _rec_name :

 class Ville(models.Model):
    _name = 'obj.ville'
    _rec_name = 'nom'

Answer 3

you need to define a method called name_get like the following

def name_get(self, cr, uid, ids, context=None):
    if context is None:
        context = {}
    if isinstance(ids, (int, long)):
        ids = [ids]
    res = []
    for record in self.browse(cr, uid, ids, context=context):
        name = record.nom_ville
        res.append((record.id, name))
    return res

Answer 4

Many2one fields are by default kind of selection fields. At first you create a model for ville with 'name' as an attribute

class OdooVillePerso(models.Model):
    _name = 'odoo.ville.perso'

    name = fields.Char('Ville')

class OdooFinalClass(models.Model):
    _name='odoo.final.class'

    ...

    ville = fields.Many2one('odoo.ville.perso', 'Ville')

After that you can just call it in another model as a Many2one and it will appear as selection field but don't forget to creata a view for the model.

PS: This code works on odoo 10
