Django URL Filter - DjangoCon US 2015 Lighting Talk

A lighting talk I gave at DjangoCon US 2015 about a library I open-sourced Django URL Filter.

More information can be found in docs at bit.ly/django-url-filter.

Transcript

1. Django URL Filter Miroslav Shubernetskiy
 @miki725miki Dealertrack Technologies DjangoCon 2015
2. Use Cases • Pagination
 (lots of data) • API
 (bulk operations) • Filtering logic
 client-side
3. Promises 1. Human-friendly URLs ;) 2. Safe filtering (validation) 3. Related fields 4. Data-source agnostic
4. 1. Human-Friendly URLs • ?id=1 • ?id!=1 # negated • ?id__in=1,2,3 • ?name__contains=Django
5. 2. Safe Filtering • ?id=1 (IntegerField) • ?id__in=1,2,3 (IntegerField) • ?username=django (CharField) • ?joined__year=2015 (Int…Field)
6. 3. Related Models • users/
 ?profile__nickname=django • users/
 ?profile__joined__gt=2015-09-09
7. 4. Data-source Agnostic • Django ORM • SQLAlchemy (in progress) • <etc> Parsing URL and filtering is decoupled
8. DRF Integration class UserViewSet(ModelViewSet):
 queryset = User.objects.all()
 serializer_class = UserSerializer
 filter_backends = [DjangoFilterBackend]
 filter_fields = ['username', 'email']
9. Vanilla Usage class UserFS(ModelFilterSet):
 class Meta(object):
 model = User q = QueryDict(‘username__icontains=django’)
 fs = UserFS(data=query,
 queryset=User.objects.all())
 filtered_users = fs.filter()
