django – 无法使用视图名称“itemimages-detail”解析超链接关

picture = models.ImageField(null=True,blank=True,upload_to="items")

所以我创建了一个新模型：

class ItemImages(models.Model):
    itemImage = models.ForeignKey(Item,related_name='pictures')
    image = models.ImageField(null=True,upload_to="items")

之后,我创建了视图集:(请注意,我不知道我在做什么)

class ItemImagesViewSet(viewsets.GenericViewSet):
    for_model = Item
    queryset = Item.objects.all()
    serializer_class = ItemImagesSerializer
    permission_classes = (permissions.IsAuthenticated,IsOwnerOrReadOnly)

然后网址转：

router = ExtendedSimpleRouter()
...
(
    router.register(r'items',ItemViewSet)
          .register(r'itemimages',ItemImagesViewSet,'items-images',parents_query_lookups=['items']) # I added this line 
          .register(r'reviews',ItemReviewViewSet,'items-review',parents_query_lookups=['content_id'])
)

我的序列化器：

from rest_framework import serializers
from django.utils.translation import ugettext_lazy as _

from inventory.models import Item,ItemImages
from users.api.serializers import ObjectReviewsSerializer


class ItemSerializer(ObjectReviewsSerializer):
    class Meta:
        model = Item
        fields = (
            'category','id','pictures','created','title','url','value','user','reviews_url','rating','description'
        )
        read_only_fields = ('user','modified','')

    def create(self,validated_data):
        validated_data.update({
            'user': self.context['request'].user,})
        return super(ItemSerializer,self).create(validated_data)

    def validate(self,attrs):
        more_fee = attrs.get('more_fee',None)
        less_fee = attrs.get('less_fee',None)
        if not more_fee and not less_time_fee and not self.instance:
            msg = _('You should provide either a more fee or a less  fee')
            raise serializers.ValidationError(msg)
        return attrs


class ItemImagesSerializer(ObjectReviewsSerializer):
    class Meta:
        model = ItemImages

它在我请求/ items / 23时给出了标题中声明的错误
我知道我做错了很多但是我不知道为什么和为什么.
我是Django Rest和Django的新手,我正在玩一个现有的项目(尝试将一张图片更改为多张)

完整的错误消息：

ImproperlyConfigured at /api/v1/items/23/ Could not resolve URL for
hyperlinked relationship using view name “itemimages-detail”. You may

configured the lookup_field attribute on this field.
