How do I get the actual object id in a Django admin page (inside formfield_for_foreignkey)?

Question

I \'ve already solved the problem of getting the object id being edited using this code:

class CompanyUserInline(admin.StackedInline):
    \"\"\"
    Defines         


        

Answer 1

The following code snippet will give you the object id:

request.resolver_match.kwargs['object_id']

Sample usage: (I'm filtering the phone numbers shown, to only show customer's phone numbers)

def formfield_for_foreignkey(self, db_field, request, **kwargs):
    if db_field.name == 'preferred_contact_number':
        kwargs['queryset'] = CustomerPhone.objects.filter(customer__pk=request.resolver_match.kwargs['object_id'])
    return super().formfield_for_foreignkey(db_field, request, **kwargs)

P.S: Found it by debugging and walking through accessible variables.
