Hi,

I want to compute age from two models : age = name - date_debut

code py :

Model 1 :

class ProductionMortalite(models.Model):

_name = 'production.mortalite'

_description ="Mortalité"

_inherit = ['mail.thread']

name = fields.Date(string='Date', default=fields.Date.context_today, track_visibility='always')

age = fields.Integer(string='Age (Jours)', readonly=True, compute='onchange_age', track_visibility='onchange')

nombre = fields.Integer(string='Nombre de mortalité', required=True, track_visibility='onchange')

cycle_id = fields.Many2one('production.cycle', string='Cycle', ondelete='cascade', readonly=True, track_visibility='onchange')

_sql_constraints = [

('name_uniq', 'unique (name, age, cycle_id)', "La date de la mortalité existe déjà !"),

]

@ api.onchange ( 'name' )

def onchange_age ( self ):

if self.name:

a = self.env['production.cycle'].search([])

self.age = self.name - a.date_debut

Model 2 :

class ProductionCycle(models.Model):

_name = 'production.cycle'

_description ="Les cycle de production"

_inherit = ['mail.thread']

name = fields.Char(string='Nom du cycle de production', required=True, track_visibility='always')

description = fields.Text(string='Description', track_visibility='onchange')

date_debut = fields.Date(string='Date de début', required=True, default=fields.Date.context_today, track_visibility='onchange')

date_fin = fields.Date(string='Date de fin', readonly=True, track_visibility='onchange')

statut = fields.Selection([('brouillon', 'Brouillon'), ('encours', 'En Cours'), ('termine', 'Terminé')], string='Statut', required=True, default='brouillon', track_visibility='onchange')

effectif_depart = fields.Integer(string='Effectif de départ', required=True, track_visibility='onchange')

mortalite_declaree = fields.Integer(string='Mortalité déclarée', readonly=True, track_visibility='onchange')

effectif_restant = fields.Integer(string='Effectif restant', readonly=True, compute='onchange_effectif_restant', track_visibility='onchange')

batiment_id = fields.Many2one('technique.batiment', string='Bâtiment', ondelete='cascade', required=True, track_visibility='onchange')

souche_id = fields.Many2one('animale.souche', string='Souche', ondelete='cascade', required=True, track_visibility='onchange')

_sql_constraints = [

('name_uniq', 'unique (name, batiment_id)', "Le nom du cycle existe déjà !"),

]

Hi Ramla,

Your onchange is going off for multiple records at once in your database. As your code does not loop over the records but just uses 'self' it will crash since you have more than one record in 'self'. You can fix it by looping over the records first:

@api.onchange('name')
def onchange_age(self):
    for record in self:
        if record.name:
            # You most likely also want a limit=1 on this search or 'a' might contain a recordset instead of a record too
            a = self.env['product.cycle'].search([])
            record.age = record.name - a.date_debut

Regards,

Yenthe

Did you try to use @api.one like this? I think it will work

@api.one
@api.onchange ( 'name' )
