Question

Since I enabled remote true, it should change the toggle button “Follow” to “Un-Follow” right away.
But it doesn’t. If I reload the page, toggle button shows changed label.
So it means that it’s actually changing the value of follow column in background.
I’ve already spent 3 days for this but I still have no idea:(
Can anyone help me how to solve this? Is there anything wrong with codes? or am I missing some file for JQuery?
I’m so newbie to Rails…

You forget the rendering into your Follows Controller.

here the code for my test i used a bit of your code but i use RubyCas-Server as layer to authentification.

So just check controller, views 🙂
