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

In config/initializers/devise.rb I put:

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

Because if you put:

$ heroku config

You'll see a secret_key_base for the mode production.

Answer 2

I ran bundle update this morning and started getting the same error.

I added it as a line in config/initializers/devise.rb and the error was fixed.

This seems to be the commit which introduced it.

Answer 3

I do not know right solution but it's working. You can try it. I was cloned my project from my GitLab account and when I run in my local server, I have an error Message:

rake aborted! Devise.secret_key was not set. Please add the following to your Devise initializer: config.secret_key = '-- secret key --'

Open config/initializers/devise.rb and add this line

config.secret_key = '<%= ENV["SECRET_KEY_BASE"] %>'

This code line is solved my problem.

Answer 4

Could it be, that you did not run rails g devise:install?

Running rails generate devise User without the previous command does cause this problem.

Answer 5

Check if your config\initializers\secret_token.rb has:

YourAppName::Application.config.secret_token

It should be:

YourAppName::Application.config.secret_key_base

Answer 6

This solved my problem:

Add the code below to your config/initializers/devise.rb file.

config.secret_key = '-- secret key --' 

Replace '-- secret key--' with your own key. I recommend storing it in an ENV variable for security purpose.
