What are some examples of using django-filter?

Django-filter is a powerful tool for filtering querysets in Django. For example, you can filter a list of books by author or publication date.

Can you show me a code snippet for filtering by author?

Sure! Here's a simple example:

from django_filters import rest_framework as filters
from .models import Book

class BookFilter(filters.FilterSet):
    author = filters.CharFilter(field_name='author__name')

    class Meta:
        model = Book
        fields = ['author']

This allows you to filter books by the author's name.

What if I want to filter by multiple fields?

You can easily add more fields to the fields list in the Meta class. For example:

class Meta:
    model = Book
    fields = ['author', 'publication_date']

This will allow filtering by both author and publication date.

Are there any built-in filters I can use?

Yes, django-filter provides several built-in filters like DateFilter, BooleanFilter, and ChoiceFilter that you can use to simplify your filtering logic.
