Copying Many2many field values to another Many2many field - odoo

Question

I need to copy many2many field content to another class' many2many field.
#api.multi
def tester(self):
context = self._context.copy()
list = []
confs = self.risque.rubrique_ids
for rec in confs:
list.append(rec.id)
self.env['test.test'].create({
'nom_risque': self.risque.nom_risque,
'rubrique_ids': [0, 0, list]
})
return {
'name': 'Evaluation',
'view_type': 'form',
'view_mode': 'tree,form',
# 'views': [{'view_mode': 'form', 'view_id': 'rub_id'}],
'res_model': 'test.test',
'type': 'ir.actions.act_window',
'res_id': self.id,
# 'target': 'new',
'flags': {'initial_mode': 'edit'},
'context': context,
}
My XML code:
<button name="tester" string="Evaluer" type="object" class="oe_highlight" />
But it returns the nom_risque and for the rubrique_ids only the last one.

Hi try out the following and please try to understand my comments, too :-)
#api.multi
# even if it's trying out something, give it an understandable name
def tester(self):
# seems to be a singleton call, so restrict it with self.ensure_one()
# no need to copy the context here, just pass it in the end
context = self._context.copy()
# odoo's recordsets has some cool functions, e.g. mapped()
# but that's only usefull on other scenarios
list = []
confs = self.risque.rubrique_ids
for rec in confs:
list.append(rec.id)
# you will call this new record later so don't forget to 'save' it
self.env['test.test'].create({
'nom_risque': self.risque.nom_risque,
# that's just plain wrong, read the __doc__ on models.BaseModel.write()
'rubrique_ids': [0, 0, list]
})
return {
'name': 'Evaluation',
'view_type': 'form',
'view_mode': 'tree,form',
# 'views': [{'view_mode': 'form', 'view_id': 'rub_id'}],
'res_model': 'test.test',
'type': 'ir.actions.act_window',
# here is the mistake: take the id of your created record above
'res_id': self.id,
# 'target': 'new',
'flags': {'initial_mode': 'edit'},
'context': context,
}
And now the hopefully working example:
#api.multi
def create_test_record(self):
self.ensure_one()
test = self.env['test.test'].create({
'nom_risque': self.risque.nom_risque,
'rubrique_ids': [(6, 0, self.risque.rubrique_ids.ids)]
})
return {
'name': 'Evaluation',
'view_type': 'form',
'view_mode': 'tree,form',
'res_model': 'test.test',
'type': 'ir.actions.act_window',
'res_id': test.id,
'flags': {'initial_mode': 'edit'},
'context': self.env.context
}
