使用 Django Rest Framework 返回当前用户 [英] Return the current user with Django Rest Framework

问题描述

我目前正在使用 Django 开发 API.

I am currently developing an API using Django.

但是，我想创建一个返回当前用户的视图，端点如下:/users/current/.

However, I would like to create a view that returns the current User with the following endpoint: /users/current/.

为此，我创建了一个列表视图并过滤了发出请求的用户的查询集.这有效，但结果是一个列表，而不是单个对象.结合分页，与其他端点相比，结果看起来过于复杂和不一致.

To do so, I created a list view and filtered the queryset on the user that made the request. That works, but the result is a list, not a single object. Combined with pagination, the result looks way too complicated and inconsistent compared to other endpoints.

我还尝试创建详细视图并过滤查询集，但 DRF 抱怨我没有提供 pk 或 slug.

I also tried to create a detail view and filtering the queryset, but DRF complains that I provided no pk or slug.

你有什么想法吗?

推荐答案

有了这样的东西，你可能最好摆脱通用视图并自己编写视图.

With something like this you're probably best off breaking out of the generic views and writing the view yourself.

@api_view(['GET'])
def current_user(request):
    serializer = UserSerializer(request.user)
    return Response(serializer.data)

你也可以使用基于类的视图来做同样的事情......

You could also do the same thing using a class based view like so...

class CurrentUserView(APIView):
    def get(self, request):
        serializer = UserSerializer(request.user)
        return Response(serializer.data)

当然，也不要求您使用序列化程序，您同样可以从用户实例中提取您需要的字段.

Of course, there's also no requirement that you use a serializer, you could equally well just pull out the fields you need from the user instance.

@api_view(['GET'])
def current_user(request):
    user = request.user
    return Response({
        'username': user.username,
        'email': user.email,
        ...
    })
