Rails/heroku: how to make work my app on heroku

Question

I have a rails (2.3.5) app and I had to make some changes on it, involving changing the db. So, locally it's working fine, but when I tryied to push it to heroku I'm having a "Application Error" on my browser when I'm trying access the app. I've pushed the new code, bootstraped and filled the heroku db with my local project.

This is what I got with "heroku logs", any ideas? :

Answer 1

Take a look at your sms controller and make sure that each def[1] is closed off with an end

The log file doesn't have to be that intimidating. Note that the critical information is stated after the app has been created and then started, because that's where the problems started, and the most vital information is closer to the top. The first line after that states the syntax error. All of the subsequent lines are errors that will disappear once the top error is fixed.

[1] Not necessarily a def - could be a block, a loop, iteration etc.

Answer 2

It looks like there's a syntax error in one of your controllers:

sms_controller.rb:232: syntax error, unexpected $end, expecting kEND (SyntaxError)
