Hello,
ModelMultipleChoiceField fields cleaned data are lists, so you are trying to
create an object with a list of ids as id. Also I think you want to retrive
the object, in that case you have to use the get function of the model
manager (e.g. Object.objects.get(id=someid). )
If you need to get all the options of a multiple choice field, you must use
a ManyToMany relationship instead of a ForeingKey.
Regards,
Matias.
