Can't get request data

I have a viewset and a function with an additional address (decorator @action). In the serializer, I define an additional field through the SerializerMethodFieldenter image description here, and in order to define it, I need to know the user data through request.user. So the problem is, when the request goes through the viewset address (…/api/users/), everything is fine, but when it go through my additional address (…/api/users/subscriptions) there is no request data and i get this user = self.context.get(‘request’).user
AttributeError: ‘NoneType’ object has no attribute ‘user’

The serializer has no information about the request that went through @action

viewset url

@action url, self.context is empty

>Solution :

Simple way using your code, just change in UserViewSet to:

.....
context = {
    'request': self.request,
    'format': self.format_kwarg,
    'view': self
}
serializer = UserSerializer(users, many=True, context=context)
.....
