python - 如何在 Django Rest 框架中设置 View

Question

我正在尝试 django Rest 框架。我想构建一个简单的 CRUD 将产品发布到数据库。但是，当我访问发布产品的网址时，出现错误。

序列化器.py

from rest_framework import serializers
from .models import Product


class ProductSerializer(serializers.ModelSerializer):
    model = Product
    fields = ("id", "name", "brand", "specs", "price", "stock", "picture")

View .py

from rest_framework import viewsets
from .serializers import ProductSerializer
from .models import Product


class ProductViewSet(viewsets.ModelViewSet):
    serializer_class = ProductSerializer
    queryset = Product.objects.all()

这是我到达发布产品的网址时遇到的错误“tuple”对象没有属性“values”

Answer 1

序列化器中的 model 和 fields 都应该位于内部 Meta 类中。

class ProductSerializer(serializers.ModelSerializer):
    class Meta:
        model = Product
        fields = ["id", "name", "brand", "specs", "price", "stock", "picture"]
