What are some examples of using django-filter in a Django project?

Can you give me some examples of how to use django-filter in a Django project?

Sure! Django-filter is a powerful library that allows you to filter querysets dynamically. For example, you can create a filter for a model like this:

import django_filters
from .models import Product

class ProductFilter(django_filters.FilterSet):
    class Meta:
        model = Product
        fields = ['category', 'price']

This will allow you to filter products by category and price.

How do I integrate this filter into my views?

You can integrate the filter in your views like this:

from django.shortcuts import render
from .models import Product
from .filters import ProductFilter

def product_list(request):
    product_filter = ProductFilter(request.GET, queryset=Product.objects.all())
    return render(request, 'product_list.html', {'filter': product_filter})

What about using it with Django REST Framework?

For Django REST Framework, you can use django-filter with your viewsets. Just add the filter backends:

from rest_framework import viewsets
from django_filters.rest_framework import DjangoFilterBackend

class ProductViewSet(viewsets.ModelViewSet):
    queryset = Product.objects.all()
    filter_backends = (DjangoFilterBackend,)
    filterset_fields = ['category', 'price']
