Rails + Heroku : We're sorry, but something went wrong

Question

Hi this is my first time trying to push a project up to Heroku and I am getting the error: We're sorry, but something went wrong. I'm not sure how to read the heroku log. Is it the deprecation warnings? I don't have anything in my vendor/plugins... Can someone help me figure out what's wrong? Let me know if you need any other files.

What's your Gemfile like? Did you specific `gem "sass", :require => 'sass'`? — fankt, Oct 24 '12 at 01:07
@evanc3 hey evan. I uploaded the gemfile for you. I have sass in my assets. — bigpotato, Oct 24 '12 at 03:50
Does the application work fine locally, without throwing these error messages? Also, check this answer for a similar issue - http://stackoverflow.com/a/11351105/429758 - and see if your's is the same situation. — Prakash Murthy, Oct 24 '12 at 04:33
@evanc3 I only have a few. and I can't seem to find any duplication of application.css. My complete code is here on github: https://github.com/EdmundMai/pholderbeta — bigpotato, Oct 24 '12 at 16:16

First, a couple of pointers. The message We're sorry, but something went wrong is what Heroku presents to the end user on any error in your application, because you're in production mode. This is different than what happens in development mode on your local machine, on the theory that you don't want to expose debug stack traces to any user of your application who comes along.

The deprecation warning is a red herring; it's about some gems that Heroku injects into every Rails application, to integrate with their log management stuff.

The really pertinent line in your error log is this one:

2012-10-23T20:29:56+00:00 app[web.1]: ActionView::Template::Error (/app/app/assets/stylesheets/application.css has already been required):

That's an error somewhere in how stylesheets are being handled, maybe in the asset pipeline feature. That's why @evanc3 is asking about how many stylesheets you have. And, I confess, I don't know how to debug this issue - so this is only a partial answer. Hopefully I've gotten you on the right path.

so does this mean if I try to deploy the app onto a real domain it won't work? or does heroku just give these errors to make sure that your app is 100% before being put in production? — bigpotato, Oct 24 '12 at 16:57
It won't work, unless there's something about how your "real domain" is configured vs Heroku. You can try to reproduce it on your local machine by running your server production-style like this: `RAILS_ENV=production rails server`. — dpassage, Oct 24 '12 at 18:20

Google with WARN: tilt autoloading 'sass' in a non thread-safe way; explicit require 'sass' suggested.

I found this answer: https://stackoverflow.com/a/12859696/1008230
Looks like the assets need be compile locally.

Here's some reference:

For faster asset precompiles, you can partially load your application by setting config.assets.initialize_on_precompile to false in config/application.rb, though in that case templates cannot see application objects or methods. Heroku requires this to be false.

http://guides.rubyonrails.org/asset_pipeline.html#precompiling-assets

While precompiling assets, in Rails 3.1.1 and up, you can prevent initializing your application and connecting to the database by ensuring that the following line is in your config/application.rb: config.assets.initialize_on_precompile = false

https://devcenter.heroku.com/articles/rails3x-asset-pipeline-cedar#troubleshooting

Haven't try it myself, hope that helps.

hey thanks it fixed that error, but my app still doesn't work (i'm guessing it's one of the other errors. I'll post you my new stackoverflow question — bigpotato, Oct 29 '12 at 17:08
