Pushing treebook to heroku - missing assets

I've deployed the app to heroku but it has lost the bootstrap files. The compiled css file referenced only contains the 40px padding and not bootstrap and my javascripts are missing. Why is this?

If you're using Ruby 2.0.0 and Rails 4, here are the steps I followed to get bootstrap functional

1) Like Gwyn suggessted you have to precompile your assets, but do it on you PRODUCTION ENV. Documentaion here,

RAILS_ENV=production bundle exec rake assets:precompile

git add public/assets

git commit -m "vendor compiled assets"

Also if using rails 4, make sure you add this to your gemfile

gem 'rails_12factor'


bundle install

before finally

git push heroku master

documents here That finally had me up and running!

I've tried changing production.rb settings but that doesn't work

Did you ever get this resolved because I am having the exact same issue.

googled it and found the answer eventually:

I had to run:

rake assets:precompile

before pushing to heroku.

Heroku logs show no issue with precompiling assets, however i did precompile before pushing, and no improvement.

I have ZERO CSS or Javascript happening.

My links work and so does registration. But no parts of twitter bootstrap are functioning.

Any other ideas?

I've also been having this issue on another app. Curious to hear an answer. It was my understanding that Heroku would try to compile assets, and locally compiling them was only a fall back. According to https://devcenter.heroku.com/articles/rails-asset-pipeline, once you do a local compile Heroku can't do slug compilation anymore since your app will have a manifest.yml file. Would love to know what the 'proper' method is.

Adding this code right below "source 'https://rubygems.org'" worked for me:

ruby '1.9.3'

Then do a 'git add .', and a 'git push heroku master'
