What are some effective filtering techniques in Django APIs?

In Django, you can use query parameters to filter data. Common techniques include using the filter() method, Q objects for complex queries, and Django REST Framework's filtering capabilities.

Can you give me an example of using the filter() method?

Sure! If you have a model called Product, you can filter products by price like this: Product.objects.filter(price__lt=100) to get products cheaper than $100.

What about using Q objects?

Q objects allow for complex queries. For example, Product.objects.filter(Q(price__lt=100) | Q(category='electronics')) retrieves products that are either under $100 or belong to the electronics category.

How can I implement filtering in Django REST Framework?

In Django REST Framework, you can use the django-filter package. Just add filter_backends = (DjangoFilterBackend,) in your viewset and define your filterset class.
