DRF路由组件分析

DRF路由组件分析

在之前进行drf开发时，对于路由我们一般进行两种配置：

• 视图继承APIView

  from django.urls import path
  from app01 import views
  
  urlpatterns = [
      path('api/users/', views.UserView.as_view()),  # APIView
  ]
  

• 视图继承 ViewSetMixin（GenericViewSet、ModelViewSet）

  from django.urls import path, re_path, include
  from app01 import views
  
  urlpatterns = [
      path('api/users/', views.UserView.as_view({"get":"list","post":"create"})),
      path('api/users/<int:pk>/', views.UserView.as_view({"get":"retrieve","put":"update","patch":"partial_update","delete":"destory"})),
  ]
  

  对于这种形式的路由，drf中提供了更简便的方式：

  from rest_framework import routers
  from app01 import views
  
  router = routers.SimpleRouter()				# routers.urls 所有的路由信息
  router.register(r'api/users', views.UserView)
  
  urlpatterns = [
      # 其他URL
      # path('xxxx/', xxxx.as_view()),
  ]
  
  urlpatterns += router.urls
  

  也可以利用include，给URL加前缀：

  from django.urls import path, include
  from rest_framework import routers
  from app01 import views
  
  router = routers.SimpleRouter()
  router.register(r'users', views.UserView)
  
  urlpatterns = [
      path('api/', include((router.urls, 'app_name'), namespace='instance_name')),
      # 其他URL
      # path('forgot-password/', ForgotPasswordFormView.as_view()),
  ]
  

额外的URL

from rest_framework.viewsets import ModelViewSet
from rest_framework.decorators import action


class XXXModelSerializer(serializers.ModelSerializer):
    class Meta:
        model = models.UserInfo
        fields = "__all__"

        
class XXXView(ModelViewSet):
    queryset = models.UserInfo.objects.all()
    serializer_class = XXXModelSerializer
	
    # detail=False: 生成URL时后面不带id
    # @action(detail=False, methods=['get'], url_path="yyy/(?P<xx>\d+)/xxx")
    # def get_password(self, request, xx, pk=None):
    #     print(xx)
    #     return Response("...")

    # @action(detail=True, methods=['get'], url_path="yyy/(?P<xx>\d+)/xxx")
    # def set_password(self, request, xx, pk=None):
    #     print(xx)
    #     return Response("...")
