Good day i seem to be lost in how i want to implement something. so here is how it goes
ive got a carowner model
class carowner(models.Model):
.....
carowner = models.CharField(primary_key=True)
and a cars model
class car(models.Model):
....
carowner_id = models.ForeignKey(carowner)
it has a foreignkey cause each car can only have one carowner but a carowner can have many cars but i run into a situation where
ive got a modelform
class assigncarownertocar(forms.ModelForm):
car= forms.ModelChoiceField(widget=MultipleSelect())
class Meta:
model=carowner
fields = [# all fields that are needed ]
what i want to happen is when im creating a new carowner asigns him multiple cars in the same form from a queryset i provided when the modelform is initialized. so everything loads fine in the form. i see the list of cars but once i select one or more i get this
'Select a valid choice. 539421 is not one of the available choices.
what i am asking is should i add the modelmultiplechoicefield to the model that holds the foreign key? cause right now i have it attached to the carowner model. i dont see documentation stating that this is wrong
