How to use the field 'in' in django-rest-framework-filters, like 'user_id__in=[12,13]'?

Use with QueryArrayWidget
It supports those strings:

1. Values can be provided as csv string:  ?foo=bar,baz
2. Values can be provided as query array: ?foo[]=bar&foo[]=baz
3. Values can be provided as query array: ?foo=bar&foo=baz

@weiyong996 For your implementation, using /api/companies?user_id__in=12,13 should give you the results you are looking for.
Ensure the UserFilter is defined in the view associated to the /companies url
