之前我用過ModelSerializer，沒有出現(xiàn)任何錯(cuò)誤。當(dāng)我用HyperlinkedModelSerializer這個(gè)錯(cuò)誤替換它時(shí)拋出了Could not resolve URL for hyperlinked relationship using view name "bookdetail". You may have failed to include the related model in your API,or incorrectly configured the `lookup_field` attribute on this field.這是serializers.py文件：class BookSerializer(serializers.HyperlinkedModelSerializer): class Meta: model = Book fields = ['id', 'url', 'title', 'subtitle', 'isbn']model.pyclass Book(models.Model): title = models.CharField(max_length=250) subtitle = models.CharField(max_length=250) author = models.CharField(max_length=100) isbn = models.CharField(max_length=13) def __str__(self): return self.titleviews.pyclass BookListView(viewsets.ModelViewSet): queryset = Book.objects.all() serializer_class = BookSerializer和urls.pyrouter = routers.DefaultRouter()router.register('books', BookListView)app_name = "books"urlpatterns = [ path('', include(router.urls)),]視圖名稱book-detail在我的視圖中不存在，可能是 Django 自動(dòng)創(chuàng)建的，但我不知道在哪里找到并調(diào)試它？謝謝。

我也曾經(jīng)遇到過這個(gè)問題，但我通過這樣做解決了：
urls.py（項(xiàng)目），
您可能需要在根目錄中為您的應(yīng)用程序提供命名空間urls.py
path('your_url', include(('your_app.urls', 'your_app'), namespace="your_app"))
serializers.py
添加一個(gè)HyperlinkedIdentityField
class BookSerializer(serializers.HyperlinkedModelSerializer):
# add this
url = serializers.HyperlinkedIdentityField(view_name="your_app:book-detail")
class Meta:
model = Book
fields = ['id', 'url', 'title', 'subtitle', 'isbn']
urls.py（應(yīng)用程序）
添加basename
router = routers.DefaultRouter()
# add basename
router.register('books', BookListView, basename="books")
