Re: Using django login functionality in a non django app

Well, not really. I have managed to invoke my django login screen from
my Qt app, but after I log in, of course my django app comes up.

What I would like is to pass in some parameter to the login screen
(which is easy), and then have my django app detect that and after
successfully or unsuccessfully logging in, return a token or error
code to the Qt app and not bring up the django app. But I'm not sure
how to do that.
