Django Rest框架过滤器

使用Django Rest框架的过滤器可以方便地对API进行数据筛选和排序。过滤器可以根据特定条件来过滤数据，使我们能够快速准确地获取所需的信息。在本文中，我们将介绍Django Rest框架过滤器的基本用法，并通过一个案例代码来说明其在实际中的应用。

python
from rest_framework import viewsets, filters
from .models import Movie
from .serializers import MovieSerializer
class MovieViewSet(viewsets.ModelViewSet):
    queryset = Movie.objects.all()
    serializer_class = MovieSerializer
    filter_backends = [filters.SearchFilter, filters.OrderingFilter]
    search_fields = ['name', 'type']
    ordering_fields = ['release_date']

python
from django.urls import include, path
from rest_framework import routers
from .views import MovieViewSet
router = routers.DefaultRouter()
router.register(r'movies', MovieViewSet)
urlpatterns = [
    path('', include(router.urls)),
]

python
from django.db import models
class Movie(models.Model):
    name = models.CharField(max_length=100)
    type = models.CharField(max_length=50)
    release_date = models.DateField()
    def __str__(self):
        return self.name

python
from rest_framework import serializers
from .models import Movie
class MovieSerializer(serializers.ModelSerializer):
    class Meta:
        model = Movie
        fields = '__all__'

python
from rest_framework import viewsets, filters
from .models import Movie
from .serializers import MovieSerializer
class MovieViewSet(viewsets.ModelViewSet):
    queryset = Movie.objects.all()
    serializer_class = MovieSerializer
    filter_backends = [filters.SearchFilter, filters.OrderingFilter]
    search_fields = ['name', 'type']
    ordering_fields = ['release_date']

python
from django.urls import include, path
from rest_framework import routers
from .views import MovieViewSet
router = routers.DefaultRouter()
router.register(r'movies', MovieViewSet)
urlpatterns = [
    path('', include(router.urls)),
]
