login_required decorator in Django: open modal instead of redirecting to another page
Question
I have a django app which has certain sections which are reserved for registered users. I have the views annotated with login_required decorator which redirects the user to a login page.
However, I would like to keep the user on the same page and open up a modal dialog prompting user to sign in(like on the website: http://www.fashiolista.com/ ). To achieve this, I thought I could setup a middleware(instead of using login_required) and return a response like below:
return HttpResponse("<script>"
"showLogin()"
"</script>")
When I try to do this, I realised that this renders a page with only the script tag, which obviously doesnt work.
I am using Bootstrap for showing modal dialogs.

Any ideas?

Instead it should be an ajax call to happen in real time, and add the modal to your base.html.
Django View:
def login_required_ajax_view(request):
if request.is_ajax():
if request.user.is_authenticated():
return JsonResponse(data={'logged_in', True})
return JsonResponse(data={'logged_in', False})
return HttpResponse("not ajax") # Add something if the call isn't ajax
Then in your javascript
// Javascript / Jquery
function login_required() {
$.ajax({
url: 'url goes here',
data: data
success: success //on success call a function checking logged_in is
//true or false then open modal to log in.
})
}
If it returns true allow them to click the button and move on to the next page.
On a side note:
If you're routing all of your urls through django and not javascript, then the modal will not appear if they go directly to a url in the browser. If this is a one page app then there is alot more to be done to get any of this to work. You need javascript libraries, a router, etc,

Just accomplish this in your template
<html>
...
{% if user.is_authenticated %}
<div class="reserved-section">...</div>
{% else %}
<script> modal(); </script>
{% endif %}
Alternatively, render different templates via your view
def some_page(request):
if request.user.is_authenticated():
return render(request, "template_a.html")
else:
return render(request, "template_b.html")
Update
Use javascript logic in your template if you need to make an action
<script>
function actionOnClick() {
var logged_in = {% if user.is_authenticated %}true{% else %}false{% end %};
if(logged_in){
..
}
..
}
</script>
