Which model field to use for the list?

Question

Django

Right now I'm using a CharField. The list looks like this ['1','2','3']. I need to filter by it, i do like this

Master.objects.filter(id__in=self.object.mylist)

. Django swears like this

invalid literal for int() with base 10: '['

. When inserting this list directly

Master.objects.filter(id__in=['1','2','3'])

, then of course everything works fine. I understand that the matter is in CharField, so the question is, which field is better to use here, or is there an option to clean up the list somehow from unnecessary characters?

Answer 1

For a list, it’s more likely then ArrayField
If, of course, you have Django from 1.8 and PostgreSQL in a DBMS
