python - DRF：视图集lookup_field 配置不当

Question

我正在将我的 DRF 从泛型迁移到视图集，但收到此错误：

Could not resolve URL for hyperlinked relationship using view name "monument-detail". You may have failed to include the related model in your API, or incorrectly configured the `lookup_field` attribute on this field.

这是我的 urls.py

from app.api import views
from rest_framework import routers

router = routers.DefaultRouter()
router.register(r'monuments', views.MonumentsViewSet)

urlpatterns = router.urls

这是我的观点

from app.api import serializers
from rest_framework import viewsets


class MonumentsViewSet(viewsets.ModelViewSet):
    serializer_class = serializers.MonumentSerializer
    queryset = serializer_class.Meta.model.objects.all()
    lookup_field = 'id'

最后是我的序列化程序

from app.api import models
from rest_framework import serializers


class MonumentSerializer(serializers.HyperlinkedModelSerializer):
    images = serializers.StringRelatedField(many=True)

    class Meta:
        model = models.Monument
        fields = '__all__'

Answer 1

删除lookup_field = 'id'. 我不知道为什么会发生这种情况，但是当我复制您的代码时它起作用了。

PS您的错误说，您错误地配置了“lookup_field”
