Following the whole installation process properly, still django debug tool is not working?

First of all don't get frustrated. Still now, Everythig is ok! Open the console of your browser and if you show the Following error -

Loading module from “http://127.0.0.1:8000/static/debug_toolbar/js/toolbar.js” was blocked because of a disallowed MIME type (“text/plain”).

then just add this two line anywhere in your settings.py file

import mimetypes
mimetypes.add_type("application/javascript", ".js", True)

Now restart the app and start coding!
Enjoy!
