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

Ran into the same trouble with Rails 5.2.0 and Devise 4.4.1

Drop the following into /config/initializers/devise.rb

config.secret_key = Rails.application.credentials.secret_key_base

Answer 2

I has same issue. The problem was caused by these lines in routes.rb:

devise_for :users, :skip => [:registrations]                                                   
as :user do
  get 'users/edit' => 'devise/registrations#edit', :as => 'edit_user_registration'              
  put 'users' => 'devise/registrations#update', :as => 'user_registration'                      
  get '/users/sign_out' => 'devise/sessions#destroy'                                            
end

I commented them and after that i run:

$ rails generate devise:install

And it has evaluated perfectly. And after that I uncommented routes.

Answer 3

As of Devise 3.2.3 for Rails 4+ applications the key setting location defaults to YourAppName::Application.config.secret_key_base found in config/initializers/secret_token.rb

Answer 4

Well, I have been following this post and tried almost everything here. I have added the key to devise.rb. But I was still getting the same error.

Maybe a stupid answer, but all I had to do was to push the devise.rb key to the repository.

Answer 5

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)

Answer 6

I cloned my repository onto a new machine from git. The

config/secrets.yml 

file was on my .gitignore list, so that file didn't exist, and Devise doesn't create the file.

I added the file, then re-ran

rails generate devise MODEL

and it worked.
