我正在使用Django Rest Framework（Django版本=4.0.4，我知道我需要升级，但我仍在学习诀窍和djangorestframework~=3.14.0）和Viewsets作为API，但我无法在列表页面上显示Browsable API POST表单。我可以看到ParameterKeys的列表（所以我认为urls.py和serializers.py是正确的），而且我使用的是超级用户帐户，所以我不认为这是权限问题。我的设置有什么问题？我确实注意到Brave浏览器代理请求有'text/html'和一些'application/xml'，但没有'application/json'...不确定是不是这样？
以下是模型的相关部分：

class ParameterKey(models.Model):
    id = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False)
    name = models.CharField(max_length=200)
    owner = models.ForeignKey(get_user_model(), on_delete=models.CASCADE, related_name='parameter_keys')

    def __str__(self):
        return self.name

以下是www.example.com的相关部分urls.py:

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

router = routers.DefaultRouter()
router.register(r'', api_views.ParameterViewSet)

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

以下是API_views.py的相关部分：

from rest_framework import viewsets, parsers
from .models import ParameterValue, ParameterKey
from .serializers import ParameterValueSerializer, ParameterKeySerializer
from parameters.permissions import IsOwnerOrPublic
# from django.http import JsonResponse
# from django.views.decorators.csrf import csrf_exempt
from rest_framework.permissions import AllowAny

class ParameterKeyViewSet(viewsets.ModelViewSet):
    permission_classes = [AllowAny]
    queryset = ParameterKey.objects.all()
    serializer_class = ParameterKeySerializer

这里是主项目urls.py:

from django.conf import settings
from django.conf.urls.static import static
from django.contrib import admin
from django.urls import path, include
from datasets.views import DatasetListView, DatasetDetailView
from datasets.api_views import DatasetViewSet
from parameters.api_views import ParameterViewSet
from rest_framework import routers
from files import views
from files.views import upload_file

router = routers.DefaultRouter()
# router.register(r'datasets', DatasetViewSet, basename='dataset')
router.register(r'datasets', DatasetViewSet, basename='dataset')
router.register(r'parameterkeys', ParameterViewSet, basename='parameterkey')  # Add this line

urlpatterns = [
    # Django admin
    path("anything-but-admin/", admin.site.urls),
    # User management
    path("accounts/", include("allauth.urls")),
    # Include URLs from the datasets app
    path("api/v1/datasets/", include("datasets.api_urls")),
    # Include URLs from the parameters app
    path("api/v1/parameters/", include("parameters.urls")),
    # Non-API view
    path("", include("datasets.urls")),
    # API views
    path("api/v1/", include(router.urls)),
    # API authentication
    path("api-auth/", include("rest_framework.urls")),
    path("api/v1/dj-rest-auth/", include("dj_rest_auth.urls")),
    path("api/v1/dj-rest-auth/registration/", include("dj_rest_auth.registration.urls")),
    path('upload/', upload_file, name='upload_file'),
] + static(
    settings.MEDIA_URL, document_root=settings.MEDIA_ROOT
)


if settings.DEBUG:
    import debug_toolbar

    urlpatterns = [
        path("__debug__/", include(debug_toolbar.urls)),
    ] + urlpatterns

以下是www.example.com的相关部分serializers.py:

from rest_framework import serializers
from .models import ParameterValue, ParameterKey

class ParameterKeySerializer(serializers.ModelSerializer):
    class Meta:
        model = ParameterKey
        fields = '__all__'

我没有发布我的settings.py，因为SO将其标记为垃圾邮件。以下是已安装的应用程序：

INSTALLED_APPS = [
    "django.contrib.admin",
    "django.contrib.auth",
    "django.contrib.contenttypes",
    "django.contrib.sessions",
    "django.contrib.messages",
    "whitenoise.runserver_nostatic",  # new
    "django.contrib.staticfiles",
    "django.contrib.sites",
    # Third-party
    "rest_framework",
    "crispy_forms",
    "crispy_bootstrap5",
    "allauth",
    "allauth.account",
    "debug_toolbar",
    "corsheaders",
    "rest_framework.authtoken",
    "dj_rest_auth", 
    "storages",
    # Local
    "accounts.apps.AccountsConfig",
    'datasets',
    'parameters',
    'files',
]

MIDDLEWARE = [
    "django.middleware.cache.UpdateCacheMiddleware",
    "django.middleware.security.SecurityMiddleware",
    "whitenoise.middleware.WhiteNoiseMiddleware",  # new
    "django.contrib.sessions.middleware.SessionMiddleware",
    "django.middleware.common.CommonMiddleware",
    "django.middleware.csrf.CsrfViewMiddleware",
    "django.contrib.auth.middleware.AuthenticationMiddleware",
    "django.contrib.messages.middleware.MessageMiddleware",
    "django.middleware.clickjacking.XFrameOptionsMiddleware",
    "debug_toolbar.middleware.DebugToolbarMiddleware",
    "django.middleware.cache.FetchFromCacheMiddleware",
]

下面是REST_FRAMEWORK设置：

REST_FRAMEWORK = {
    "DEFAULT_PERMISSION_CLASSES": [
        "rest_framework.permissions.IsAuthenticatedOrReadOnly",  # new
    ],
    "DEFAULT_AUTHENTICATION_CLASSES": [  # new
        "rest_framework.authentication.SessionAuthentication",
        "rest_framework.authentication.TokenAuthentication",
    ],
        'DEFAULT_RENDERER_CLASSES': [
        'rest_framework.renderers.JSONRenderer',
        'rest_framework.renderers.BrowsableAPIRenderer',
    ],
}

我试过改变权限和不同的浏览器，我试过暂时禁用十字头。我相信问题出在某个地方的设置上，因为我的任何应用程序都没有在Browsable API中获得POST表单。当我写自己的视图时（即在我切换到视图集之前），我确实在不同的应用程序上有正确的表单。
