Django: decorator in class based view

Question

I want to restrict access to a particular view so that only AJAX requests are accepted, so I implemented the following decorator:

def require_ajax(func):
    def decorator(func):
        def inner(request, *args, **kwargs):
            if not request.is_ajax():
                return HttpResponseBadRequest()
            return func(request, *args, **kwargs)
        return inner

    return decorator

This works perfectly in function views, but I cannot figure out how to use it in class based views. I have tried this but got errors, I assume due the old version of Django I am using.

And well, my class-based view:

class AjaxView(TemplateView):
  template_name = '...'

  def get_context_data(self, **kwargs):
    ...
    return context

  @method_decorator(require_ajax)
  def dispatch(self, *args, **kwargs):
      return super(AjaxView, self).dispatch(*args, **kwargs)

Answer 1

Implementing the decorator differently solved the issue:

def require_ajax(func):
    def decorator(request, *args, **kwargs):
        if not request.is_ajax():
            return HttpResponseBadRequest()
        return func(request, *args, **kwargs)

    return decorator
