Rails ENV Variables

Question

I have recently asked a similar question to this but as the problem has moved on slighty I have decided to create a new question - I hope this is the expected approach?

Having pushed my Rails 4 app to Heroku I keep getting an Internal Server Error Page and the error is:

You must set config.secret_key_base in your app's config

This is happening because my .gitignore file includes the config/initializers/secret_token.rb deliberately.

I have installed the Figaro gem so that I could set my secret_key_base as an environment variable for added security. I have checked on Heroku that the key has been set correctly.

My code for the secret_token.rb is as follows:

MyApp::Application.config.secret_key_base = ENV["SECRET_KEY_BASE"]

However, I'm still getting the same issue.

Can anyone help???

Answer 1

I did something simlilar to you that worked, but didn't use Figaro. I based it off this blog post

In summary, here's what I did:

1) remove config/initializers/secret_token.rb from your .gitignore

2) Use this code for your secret_token.rb:

MyApp::Application.config.secret_token = if Rails.env.development? or Rails.env.test?
  ('x' * 30) # meets minimum requirement of 30 chars long
else
  ENV['SECRET_TOKEN']
end

3) commit and re-push

4) set Heroku env variale like:

heroku config:set SECRET_TOKEN=12345.....

Worked as soon as Heroku restarted after the config set.
