class tags(models.Model):

    tag = models.CharField(max_length=15)               # Tag name

    tagSlug = models.CharField(max_length=400)          # Extra info can be added to the existing tag using this field
    createdAt = models.DateTimeField(auto_now_add=True) # Time at which tag is created
    updatedAt = models.DateTimeField(auto_now=True)     # Time at which tag is updated

特定のタグに関連するすべてのストアを検索したい。 for t in tags.objects.all(): print ([str(a.storeName) for a in t.stores_set.all()]) 上記のforループを使用することで、すべての店舗に関連するすべてのタグを取得できます...しかし、実際にはDjango rest-frameWorkを使用しています...今、シリアライザーを使用して関連する店舗の名前を返すビューがあります店に...

class tagList(generics.ListAPIView,APIView):

    serializer_class = getAllTagsDetailSerializer

    def get_queryset(self):
        key = self.request.QUERY_PARAMS.get('appKey', None)
        getTagName = self.request.QUERY_PARAMS.get('tagName', None)
        keyData = app.objects.filter(appKey=key).exists()    
        try:
            if keyData == True:

                return tags.objects.filter(tag=getTagName)
            else:
                raise exceptions.PermissionDenied
        except app.DoesNotExist:
            pass

`class getAllStoresDetailSerializer(serializers.ModelSerializer):
    storeImage = serializers.Field(source='imageURL')
    storeTags =serializers.Field(source='StoreTags')

    class Meta:
        model = stores
        fields = ('storeName','storeDescription','storeURL',
                    'storePopularityNumber','storeImage','storeTags',
                    'storeSlug','createdAt','updatedAt'
                 )`


class getAllTagsDetailSerializer(serializers.ModelSerializer):
    tagStores = RelatedField(Many=True)
    class Meta:
        model = tags
        fields = ('tagStores'                   
                    )

しかし、これは機能していません...誰か助けてください...
