Trying to launch an app on Heroku, but it keeps getting an application error. Here are the heroku logs, Please let me know what I can do to get it the application running. We have implemented pusher and can get the website to work on local host (even the pusher features across different localhost machines) but other than that it does not work on heroku.

Something is trying to POST to /comments and you haven’t defined a create method on the CommentsController. What if you implement that method? – Buck Doyle Nov 4 '12 at 20:39
Which steps have you done using the Heroku Toolbox leading up to this point? – vgoff Nov 4 '12 at 21:01
This isn't an incoming request -- it's a problem loading the CommentsController class. (I think line 2 includes a call to post -- maybe it's a misplaced route definition?) What is the contents of app/controllers/comments_controller.rb? – willglynn Nov 5 '12 at 15:02

As you mentioned, you are not getting this error while working normally on your local host. Try to remove or comment the CommentsController call and check whether you are able to deploy the application on Heroku? And once you make the application run, then you can enable and check what is really making the cause for this error.
