Rails: Heroku Deploying for the First Time Failed

I thought the problem was that I was using a SQLite3, so I migrated to PostgreSQL but the problem persists. The app works fine locally. I open my app with heroku open, it gives me the following error:

Application Error. An error occurred in the application and your page could not be served. Please try again in a few moments. If you are the application owner, check your logs for details..

I tried to find the resolution by looking at the logs but failed, so I need someone's help. Here are my logs and I appreciate any help!

You've got Formtastic included in your gemfile, right? – rjz
yes! group :assets do gem 'sass-rails', '~> 3.2.3' gem 'coffee-rails', '~> 3.2.1' gem 'bootstrap-sass' gem 'formtastic-bootstrap' – Maximus S
Have you tried doing bundle install before running rails server? – Leo Correa
Yes, and bundle install gave me errors too. I think there's a problem with heroku.bat and I need to set the PATH to C:\railsinstaller\Ruby1.9.3 .. do you think that's correct? – Maximus S
Ok, the problem was that the "RailsInstaller" and "heroku-toolbelt" were causing each other a problem, so I decided to remove heroku-toolbelt and include it as a gemfile instead. However, I still do not see what my problem was with the deployed app. – Maximus S

For first-time deployers, here are the problems I had, and how I solved them:

1. RailsInstaller and Heroku Toolbelt are not perfectly compatible: If you encounter problems after you install Heroku toolbelt, I suggest you delete railsinstaller and heroku toolbelt alltogether, and install railsinstaller again. Then, in your gem file, simply add gem 'heroku' and run bundle install. I didn't need any extra stuff to successfully deploy my app. Heroku Toolbelt installs ruby 1.9.2 v, and adds wrong path to your preference. You can choose to manually fix this PATH to the right location, ex) C:RailsInstaller:Ruby1.9.3 but I found it easier to reinstall everything.

2. You have to migrate from SQLite3 to PostgreSQL: follow this if you are unsure how to do it.

3. Follow Heroku tutorial to finally deploy your app: follow this. If you get errors that say something along line with "objects do not exist," try running heroku run rake db:migrate.

Good luck deploying!
