项目环境： python3.9   Django2.2


今天在学习Django rest framework框架


使用HyperlinkedModelSerializer   时   fields 加上‘url‘后，在用POST方法添加数据后就回报错：
Could not resolve URL for hyperlinked relationship using view name "game-detail". You may have failed to include the related model in your API, or incorrectly configured the `lookup_field` attribute on this field.

serializer.py

1. class GameSerializer(serializers.HyperlinkedModelSerializer):
   
2.     class Meta:
   
3.         model = Game
   
4.         fields = ('url', 'g_name', 'g_price')

复制代码

views.py

1. from rest_framework.generics import ListCreateAPIView, RetrieveUpdateDestroyAPIView
   
2. 
   
3. from App.models import Game
   
4. from App.serializers import GameSerializer
   
5. 
   
6. 
   
7. # Create your views here.
   
8. class GamesView(ListCreateAPIView):
   
9.     serializer_class = GameSerializer
   
10.     # model = Game
    
11.     queryset = Game.objects.all()
    
12. 
    
13. 
    
14. class GameView(RetrieveUpdateDestroyAPIView):
    
15.     serializer_class = GameSerializer
    
16.     queryset = Game.objects.all()

复制代码

urls.py

1. from django.urls import path
   
2. 
   
3. from App import views
   
4. 
   
5. app_name = 'App'
   
6. urlpatterns = [
   
7.     path('games/', views.GamesView.as_view(), ),
   
8.     path('games/<int:pk>/', views.GameView.as_view(), name='game-detail'),
   
9. ]
