基于ManyToManyField关系获取对象时出现问题

我有膳食模型和成分，膳食与成分有很多关系。我尝试获得与Ingredientmodels.py匹配的对象

class Meal(models.Model):
    name = models.CharField(max_length=250)
    description = models.TextField(blank=True, null=True)
    recipe = models.TextField()
    is_published = models.BooleanField(default=False)
    user = ForeignKey(User, verbose_name='User', on_delete= models.CASCADE)
    difficulty = ForeignKey('Difficulty', on_delete=models.PROTECT, null=True)
    ingridients = models.ManyToManyField('Ingridient')
    ico = models.CharField(max_length=500, blank=True, null=True)

class CategoryIngridients(models.Model):
    name = models.CharField(max_length=100, db_index=True)

    def __str__(self):
        return self.name

class Ingridient(models.Model):
    name = models.CharField(max_length=100, db_index=True)
    category = ForeignKey('CategoryIngridients', on_delete=models.CASCADE, null=True)

    def __str__(self):
        return self.name

序列化程序.py

class MealSerializer(serializers.ModelSerializer):
    category = serializers.StringRelatedField()
    difficulty = serializers.StringRelatedField()
    #ingridients = serializers.StringRelatedField()
    user = serializers.StringRelatedField()
    class Meta:
        model = Meal
        fields = "__all__"

class IngrigientSerializer(serializers.ModelSerializer):
    category = serializers.StringRelatedField()
    class Meta:
        model = Ingridient
        fields = "__all__"

视图.py

class TestCraft(APIView):
    def post(self, request):
        ingridients_tmp = request.data['ingredients']
        ingrid = Ingridient.objects.filter(id__in=ingridients_tmp)
        print(ingrid)
        queryset = Meal.objects.filter(ingridients__in=ingrid)
        print(queryset)
        serializer = MealSerializer(queryset, many=True)
        return Response(serializer.data)

如果我POST json：

{"ingredients":[1,2]}

此视图返回，但它们正在重复：

        "difficulty": "Medium",

            6
        ]
    },

            1,
            2
        ]
    }
]

您还可以建议：我如何创建类TestCraft（APIView），以便通过一条路径我可以使用json中的成分，也可以检索膳食（queryset）？
