Django authentication and Ajax – URLs that require login

by

I am facing the same issue, and, like you, I would like a simple decorator to wrap around a Django ajax view in order to handle authentication in the same way that I have other views. One approach that seems promising to me is to use such a decorator in conjunction with JavaScript that looks for a certain value in the response.

Here is first revised draft of the decorator:

from functools import wraps

def ajax_login_required(view_func):
    @wraps(view_func)
    def wrapper(request, *args, **kwargs):
        if request.user.is_authenticated():
            return view_func(request, *args, **kwargs)
        json = simplejson.dumps({ 'not_authenticated': True })
        return HttpResponse(json, mimetype="application/json")
    return wrapper

Here is the view:

@ajax_login_required
def ajax_update_module(request, module_slug, action):
    # Etc ...
    return HttpResponse(json, mimetype="application/json")

And here is the JavaScript (jQuery):

$.post('/restricted-url/', data, function(json) {
    if (json.not_authenticated) {
        alert('Not authorized.');  // Or something in a message DIV
        return;
    }
    // Etc ...
});

EDIT: I’ve attempted to use functools.wraps, as suggested. I have not actually used this decorator in working code, so beware of possible bugs.
