• 在视图集中创建额外的动作，动作名可以自己根据需求来定义
  • 创建url路由，路由中需要使用关系映射，在as_view()中定义，把自定义的动作名映射进来，例如：{ ‘get’, ‘createTime’ }，其中createTime就是自定义的动作方法，key依旧是已经定义好的get、post、put、delete等 ```python import datetime from rest_framework.viewsets import ModelViewSet from rest_framework.response import Response from .serializers import UserProfileSerializers from .models import UserProfile

class UserExtraActionViewSet(ModelViewSet): ‘’’ 视图集额外的动作 ‘’’ queryset = UserProfile.objects.all() serializer_class = UserProfileSerializers

  1. # 通过创建时间来查询用户信息
  2. def createTiem(self, request):
  3.     starttime = datetime.date(2020, 11, 11)
  4.     endtime = datetime.date(2020, 11, 13)
  5.     user = UserProfile.objects.filter(
  6.         date_joined__range=[starttime, endtime])
  7.     serializer = self.get_serializer(instance=user, many=True)
  8.     return Response(serializer.data)
### urls.py

from django.urls import path from . import views

urlpatterns = [ path(‘extra’, views.UserExtraActionViewSet.as_view( {‘get’: ‘createTiem’}), name=”extra”) ]

  2. - 使用partial=True来设定更新部分时只传入部分数据即可，不必传入全部数据
  3. ```python
  4. import datetime
  5. from rest_framework.viewsets import ModelViewSet
  6. from rest_framework.response import Response
  7. from .serializers import UserProfileSerializers
  8. from .models import UserProfile
  10. class UserExtraActionViewSet(ModelViewSet):
  11.     ''' 视图集额外的动作 '''
  12.     queryset = UserProfile.objects.all()
  13.     serializer_class = UserProfileSerializers
  14.     lookup_url_kwarg = 'id'
  16.    # 更新用户名字
  17.     def update_username(self, request, id):
  18.         user = self.get_object()
  19.         data = request.data
  20.         serializer = self.get_serializer(
  21.             instance=user, data=data, partial=True) ### partial=True在序列化器对象中设置
  22.         serializer.is_valid(raise_exception=True)
  23.         serializer.save()
  24.         return Response(serializer.data, status=status.HTTP_201_CREATED)
