Hi, I created a res.label model:

class res_label(osv.osv):

    _name = 'res.label'

    _columns = {

        'label': fields.char('Label'), }

and added to res.partner a label_id field:

class res_partner(osv.Model):

    _inherit = "res.partner"

    _columns = {

         'label_id' : fields.many2one('res.label', 'Label')}

But when I creat a label in res.partner it displays 'res.label,1' instead of "My Label" 

anyone knows what I should do to get it works?
