'WSGIRequest'对象没有属性'data'

Question

我在发布到我的API时遇到了麻烦,并且无法弄清楚错误的含义.如果重要的话,我正在使用Django REST并包含回溯.

if (repeat == false) {
    post_data = {'User': usernameInput}
    $.ajax({
        type: 'POST',
        url: '/0/addUser',
        data: post_data,
        async: true
    })
}

class AddUser(APIView):
    def post(self, request, format = None):
        serializer = UserSerializer(data=request.data)
        if serializer.isvalid():
            serializer.save()
            return Response(serializer.data, status=status.HTTP_201_CREATED)


Traceback:

Answer 1

Django REST Framework有自己的Request对象,它包装HttpRequestDjango传入的对象,并添加了一些额外的功能(如自定义渲染和另一个身份验证层).如果在Request不存在的对象上访问任何属性,它将自动将其代理到底层HttpRequest,因此通常您不会注意到差异.

在DRF 2.x中,Request属性具有DATA和FILES属性,用于存储传入的数据以及已检测到的任何文件.这些在DRF 3.0中合并,并替换为单一data属性.随着DRF 3.0的发布,所有文档现在都反映了新Request.data属性.

您似乎正在使用Django REST Framework 2.x,但您正在尝试访问DRF 3.0中引入的新属性.因为它不存在于Request对象上,所以它被代理到HttpRequest对象,在那里它也没有被找到.

如果您在使用视图方法时遇到此问题，则可以尝试使用@api_view装饰器

from rest_framework.decorators import api_view

@api_view(["POST"])
def Function(request, <other-stuff>):
    # do the thing
