Hello
I have used the following command to update a many2many field :
rec2.list_packs =(3,[pack_id for pack_id in self.pack_ref.ids])
The problem is that i get this erreur message :
The operation cannot be completed, probably due to the following:
- deletion: you may be trying to delete a record while other records still reference it
- creation/update: a mandatory field is not correctly set
[object with reference: affichage2_pack_stock - affichage2.pack.stock]
Hello Zakaria,
Below is the possible way to update, remove or add values in the many2many field:
(0, 0, { values }) link to a new record that needs to be created with the given values dictionary
(1, ID, { values }) update the linked record with id = ID (write values on it)
(2, ID) remove and delete the linked record with id = ID (calls unlink on ID, that will delete the object completely, and the link to it as well)
(3, ID) cut the link to the linked record with id = ID (delete the relationship between the two objects but does not delete the target object itself)
(4, ID) link to existing record with id = ID (adds a relationship)
(5) unlink all (like using (3, ID) for all linked records)
(6, 0, [IDs]) replace the list of linked IDs (like using (5) then (4, ID) for each ID in the list of IDs)
Thanks

Normally get this error when value to a required field is not supplied, check whether there is a required field if so give value to the field also
