AttributeError: type object has no attribute 'get_extra_actions'

Question

我有一个小型网络应用程序，我正在尝试为其开发 API。我在一个名为 UserPlatforms 的应用程序中调用了一个名为 Platform 的模型时遇到问题。同样的错误：AttributeError: type object 'UserPlatformList' has no attribute 'get_extra_actions'

models.py:

class Platform(models.Model):
    user = models.ForeignKey(settings.AUTH_USER_MODEL,
                             related_name='platform_owned',
                             on_delete=models.CASCADE,
                             default=10)

    PLATFORM_CHOICES = [platform_x, platform_y]

    platform_reference = models.CharField(max_length=10, choices=PLATFORM_CHOICES, default='platform_x')
    platform_variables = models.JSONField()

api/views.py

from .serializers import PlatformSerializer
from rest_framework import generics, permissions
from userplatforms.models import Platform

class UserPlatformList(generics.ListCreateAPIViewAPIView):
    queryset = Platform.objects.all()
    permisson_classes = [permissions.IsAuthenticatedOrReadOnly]
    serializer_class = PlatformSerializer

api/serializer.py

from rest_framework import serializers
from userplatforms.models import Platform
    
class PlatformSerializer(serializers.HyperlinkedModelSerializer):
        class Meta:
            model = Platform
            fields = '__all__'

api/urls.py

from django.urls import path, include
from . import views
from rest_framework import routers

router = routers.DefaultRouter()
router.register(r'userplatforms/', views.UserPlatformList, 'userplatforms')
router.register(r'userfiles/', views.UserFileList, "userfiles")
router.register(r'users/', views.UserList, "user")



urlpatterns = [
    path("^", include(router.urls))
]

Answer 1

将class PlatformSerializer(serializers.HyperlinkedModelSerializer):更改为class PlatformSerializer(serializers.ModelSerializer):

Answer 2

您不能在路由器中添加通用视图

所以删除这一行

router.register(r'userplatforms/', views.UserPlatformList, 'userplatforms')

并将urlpatterns更新为

urlpatterns = [
    path('userplatforms/', views.UserPlatformList, name='userplatforms'),
    path("^", include(router.urls))
]

Answer 3

api/views.py

from .serializers import PlatformSerializer
from rest_framework import generics, permissions
from userplatforms.models import Platform

class UserPlatformList(generics.ListCreateAPIViewAPIView):
    queryset = Platform.objects.all()
    permisson_classes = [permissions.IsAuthenticatedOrReadOnly]
    serializer_class = PlatformSerializer

对于 UserPlatformList 继承，ListCreateAPIViewAPIView 应该是 ListCreateAPIView

如果你使用 mixins 创建视图集，那么它应该像

from .serializers import PlatformSerializer
from rest_framework import generics, permissions, viewsets
from userplatforms.models import Platform

class UserPlatformList(generics.ListModelMixin, viewsets.GenericViewSet):
    queryset = Platform.objects.all()
    permisson_classes = [permissions.IsAuthenticatedOrReadOnly]
    serializer_class = PlatformSerializer

这种方式路由器可以用来设置urlpatterns

api/urls.py

from django.urls import path, include
from . import views
from rest_framework import routers

router = routers.DefaultRouter()
router.register(r'userplatforms/', views.UserPlatformList, 'userplatforms')
router.register(r'userfiles/', views.UserFileList, "userfiles")
router.register(r'users/', views.UserList, "user")


urlpatterns = router.urls
