Django Rest Framework 的一些理解 about creamidea.github.com

[creamidea]

在 ViewSet 里面可以声明

• 权限控制
• 限流
• 序列化的方式
• 分页

[creamidea]

Serializer 里面声明

• Model
• Model 字段（高级定义）

[creamidea]

from django.urls import path, include
from django.contrib.auth.models import User
from rest_framework import routers, serializers, viewsets

# Serializers define the API representation.
class UserSerializer(serializers.HyperlinkedModelSerializer):
    class Meta:
        model = User
        fields = ['url', 'username', 'email', 'is_staff']

# ViewSets define the view behavior.
class UserViewSet(viewsets.ModelViewSet):
    queryset = User.objects.all()
    serializer_class = UserSerializer

# Routers provide an easy way of automatically determining the URL conf.
router = routers.DefaultRouter()
router.register(r'users', UserViewSet)

# Wire up our API using automatic URL routing.
# Additionally, we include login URLs for the browsable API.
urlpatterns = [
    path('', include(router.urls)),
    path('api-auth/', include('rest_framework.urls', namespace='rest_framework'))
]

queryset 是框架内部获取数据的基石。这个是静态声明。如果需要动态，可以在 ViewSet 里面实现 get_queryset，返回 QuerySet 类型
