视图简介
个人觉得路由和视图联系非常大。
视图编写
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（自定义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
