How do you use Django-filter's '__in' lookup?
django, python
Solution
There's a simple solution with `django_filter` now:
class BookView(viewsets.ReadOnlyModelViewSet):
serializer_class = BookSerializer()
model = Book
filter_fields = {
'id': ['exact', 'in'],
'name': ['exact']
}
And then you can use it in your query string exactly as you wanted: `?id__in=1,2,3`.
Problem
I am using Django REST framework with the `django-filter` package, but my question is mostly about `django-filter`. I don't understand how to use filters with "__in" lookup. For example I have the following model: ``` class Book(models.Model): name = models.CharField(max_length=100) class BookView(viewsets.ReadOnlyModelViewSet): serializer_class = BookSerializer() model = Book filter_fields = ('id', 'name') ``` And I can't use URLs like `/v1/books/?id__in=1,2,3` to find books with id 1, 2 or 3.
