Rails upgrade undefined method `cookie_verifier_secret`

Question

I got a warning about fatigue in the latest version.

Now I can not start the server at all, I get config/initializers/cookie_verification_secret.rb:7:in <top (required)>': undefined method cookie_verifier_secret=' for ActionController::Base:Class (NoMethodError)

Answer 1

The fix was to change:

 config/initializers/cookie_verification_secret.rb 

Change:

 ActionController::Base.cookie_verifier_secret= 

to

 ActionController::Base.config.secret_token=
