嘗試根據(jù)他們的文檔使用drf_yasg記錄 API，但我收到此錯(cuò)誤“AttributeError：‘function’對象沒有屬性‘with_ui’”?這是我在?urls.py中的代碼schema_view = get_schema_view(? ? openapi.Info(? ? ? ? title="Blog API",? ? ? ? default_version='v1',? ? ? ? description="A sample API for learning DRF",? ? ? ? terms_of_service="https://www.google.com/policies/terms/",? ? ? ? contact=openapi.Contact(email="riajulkashem@gmail.com"),? ? ? ? license=openapi.License(name="BSD License"),? ? ),? ? public=True,? ? permission_classes=(permissions.AllowAny,),)urlpatterns = [? ? path('swagger/', schema_view.with_ui('swagger', cache_timeout=0), name='schema-swagger-ui'),? ? path('redoc/', schema_view.with_ui('redoc', cache_timeout=0), name='schema-redoc'),]
