django restframework框架九 視圖

視圖簡介

?個人覺得路由和視圖聯(lián)系非常大。

視圖編寫

a. GenericViewSet

urls.py

from django.conf.urls import url, include
from app01 import views

urlpatterns = [
    url(r'test/', view.TestView.as_view({'get':'list'}), name='test'),
    url(r'detail/(?P<pk>\d+)/', view.TestView.as_view({'get':'list'}), name='xxxx'),
]

views.py

#!/usr/bin/env python
# -*- coding:utf-8 -*-
from rest_framework import viewsets
from rest_framework.response import Response


class TestView(viewsets.GenericViewSet):
    def list(self, request, *args, **kwargs):
        return Response('...')

    def add(self, request, *args, **kwargs):
        pass

    def delete(self, request, *args, **kwargs):
        pass

    def edit(self, request, *args, **kwargs):
        pass

views.py

b. ModelViewSet（自定義URL）

urls.py

from django.conf.urls import url, include
from app01 import views

urlpatterns = [
    url(r'^test/$', views.UserViewSet.as_view({'get': 'list', 'post': 'create'})),
    url(r'^test/(?P<pk>\d+)/$', views.UserViewSet.as_view(
        {'get': 'retrieve', 'put': 'update', 'patch': 'partial_update', 'delete': 'destroy'})),

views.py

#!/usr/bin/env python
# -*- coding:utf-8 -*-
from rest_framework.viewsets import ModelViewSet
from rest_framework import serializers
from .. import models


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


class UserViewSet(ModelViewSet):
    queryset = models.UserInfo.objects.all()
    serializer_class = UserSerializer

c. ModelViewSet（rest framework路由）

urls.py

from django.conf.urls import url, include
from rest_framework import routers
from app01 import views

router = routers.DefaultRouter()
router.register(r'users', views.UserViewSet)
router.register(r'groups', views.GroupViewSet)

# Wire up our API using automatic URL routing.
# Additionally, we include login URLs for the browsable API.
urlpatterns = [
    url(r'^', include(router.urls)),
]

views.py

from rest_framework import viewsets
from rest_framework import serializers


class UserSerializer(serializers.HyperlinkedModelSerializer):
    class Meta:
        model = models.User
        fields = ('url', 'username', 'email', 'groups')


class GroupSerializer(serializers.HyperlinkedModelSerializer):
    class Meta:
        model = models.Group
        fields = ('url', 'name')
        
class UserViewSet(viewsets.ModelViewSet):
    """
    API endpoint that allows users to be viewed or edited.
    """
    queryset = User.objects.all().order_by('-date_joined')
    serializer_class = UserSerializer


class GroupViewSet(viewsets.ModelViewSet):
    """
    API endpoint that allows groups to be viewed or edited.
    """
    queryset = Group.objects.all()
    serializer_class = GroupSerializer
