从Django创建Rest API

如何解决从Django创建Rest API

我创建了模型来保存产品，类别和ProductCategory。

class Product(models.Model):
    ...
    title = models.CharField(max_length=100,default = '')                                  
    ...

class Category(models.Model):
    name = models.CharField(max_length = 20,default = '')

class ProductCategory(models.Model):
    product = models.ForeignKey(Product,default=None,on_delete=models.CASCADE)
    category = models.ForeignKey(Category,on_delete=models.CASCADE)

该模型的序列化器：

class ProductSerializer(serializers.ModelSerializer):
    class Meta:
        model = Product
        fields = '__all__'

class CategorySerializer(serializers.ModelSerializer):
    class Meta:
        model = Category
        fields = '__all__'

class ProductCategorySerializer(serializers.ModelSerializer):
    
    class Meta:
        model = ProductCategory
        fields = '__all__'

ViewSets

class ProductViewset(viewsets.ModelViewSet):
    queryset = models.Product.objects.all()
    serializer_class = serializers.ProductSerializer

class CategoryViewset(viewsets.ModelViewSet):
    queryset = models.Category.objects.all()
    serializer_class = serializers.CategorySerializer

class ProductCategoryViewset(viewsets.ModelViewSet):
    queryset = models.ProductCategory.objects.all()
    serializer_class = serializers.ProductCategorySerializer

直到现在，我可以将数据添加到每个表并从Django REST框架中查看它们。

Json回复：

产品：

[
...
   {
      "id": 1,"title": "Jacket One",}
...
]

类别

[
    ...
       {
          "id": 1,"name": "Jacket",}
    ...
    ]

产品类别

[
    ...
       {
          "id": 1,"product": 1,"category": 1
       }
    ...
    ]

我要创建的实际json是：

[
    "jacket":[
        {
          "id": 1,}
       ......other jacket products......
     ],........ other categories with their products ............

]

我如何实现这种json。我尝试加入模型并在queryset中进行过滤，但无法弄清楚。朝正确方向的任何帮助将不胜感激。谢谢。
