Devise Secret Key was not set

Question

I am developing a Rails 4 app using the Active Admin gem for the administration back end. Active Admin in turn uses Devise for user authentication. Now, when I try to deploy

Answer 1

Fix:

1. In the production server:

   sudo -H nano /etc/environment
   

2. Then in the file add:

   export SECRET_KEY_BASE="yourkey"
   export DEMO03_DATABASE_PASSWORD="yourpass"
   

   to set this permanently, and system wide (all users, all processes) add set variable

3. In the local project devise.rb file:

   config.secret_key = ENV["SECRET_KEY_BASE"] if Rails.env.production?
   

Technical details:

• Ubuntu 16.04
• Devise (4.2.0)
• rails 5.0.1
• capistrano (3.7.1)
