class AnimaleSouche(models.Model):

_name = 'animale.souche'

_description ="Les souches des animaux"

name = fields.Char(string='Nom de la souche', required=True)

image = fields.Binary(string='Image')

description = fields.Char(string='Description')

programme_norme = fields.Many2many('animale.programme.norme', 'animale.souche', string='Programme de norme', ondelete='cascade', required=True)

programme_production = fields.Many2many('animale.programme.production', 'animale.souche', string='Programme de production', ondelete='cascade', required=True)

same model

Hello

for given many2many of same model you have to pass the table/relationship table name into the definition of the field.

for eg

partner_ids1 = fields.Many2many('res.partner', 'relation_table_one', 'col1', 'col2', string="Line1")
partner_ids2 = fields.Many2many('res.partner', 'relation_table_two', 'col1', 'col2', 'string="Line2")

try like this, may this will helps you.

Hi,

programme_norme = fields.Many2many('animale.souche', 'animale.programme.norme', 'animale_souche_id', 'animale_programme_norme_id', string='Programme de norme')

programme_production = fields.Many2many('animale.souche', 'animale.programme.production', 'animale_souche_id', 'animale_programme_production_id', string='Programme de production')

programme_production = fields.Many2many('animale.souche', 'animale_programme_production', 'animale_souche_id', 'animale_programme_production_id', string='Programme de production')

give the relation name with underscore. and make sure that the name is not exist into the system. so give the name like "table_rel_animale_programme_production"

programme_norme_ids = fields.Many2many('animale.programme.norme', 'animale_programme_norme_animale_souche_rel', 'animale_souche_id', 'animale_programme_norme_id', string='Programmes de norme')

programme_production_ids = fields.Many2many('animale.programme.production', 'animale_programme_production_animale_souche_rel', 'animale_souche_id', 'animale_programme_production_id', string='Programmes de production')

"programme_production_ids" works but "programme_norme_ids" no
