Redirecting after AJAX post in Django

http://hunterford.me/how-to-handle-http-redirects-with--jquery-and-django/

Edit: source unavailable

this one works for me, perhaps looks like hack

django middleware

from django.http import HttpResponseRedirect

class AjaxRedirect(object):
    def process_response(self, request, response):
        if request.is_ajax():
            if type(response) == HttpResponseRedirect:
                response.status_code = 278
        return response

javascript

$(document).ready(function() {
    $(document).ajaxComplete(function(e, xhr, settings) {
        if (xhr.status == 278) {
            window.location.href = xhr.getResponseHeader("Location");
        }
    });
});

Ajax will not redirect pages!

What you get from a redirect is the html code from the new page inside the data object on the POST response.

If you know where to redirect the user if whatever action fails, you can simply do something like this:

On the server,

In case you have an error

response = {'status': 0, 'message': _("Your error")} 

If everything went ok

response = {'status': 1, 'message': _("Ok")} # for ok

Send the response:

return HttpResponse(json.dumps(response), content_type='application/json')

on the html page:

$.post( "{% url 'your_url' %}", 
         { csrfmiddlewaretoken: '{{ csrf_token}}' , 
           other_params: JSON.stringify(whatever)
         },  
         function(data) {
             if(data.status == 1){ // meaning that everyhting went ok
                // do something
             }
             else{
                alert(data.message)
                // do your redirect
                window.location('your_url')
             }
        });

If you don't know where to send the user, and you prefer to get that url from the server, just send that as a parameter:

response = {'status': 0, 'message': _("Your error"), 'url':'your_url'} 

then substitute that on window location:

 alert(data.message)
 // do your redirect
 window.location = data.url;
