Question

I am trying to set the fb app id (used by omniauth) so that its global to devise initialiser and to the controllers.

MORE INFO

I need it in devise initialiser (config/initializer/devise.rb) so that I can set
config.omniauth :facebook, fb_app_id, fb_app_secret

Attempted Solution

I tried adding this info into a yml file ( http://railscasts.com/episodes/85-yaml-configuration-file ), however, looks like the yml hash is set for the controllers, but I can not use it for the devise initialiser.

/home/ubuntu/myapp/config/initializers/devise.rb:215:in `block in <top (required)>': uninitialized constant APP_CONFIG (NameError)

Any ideas?

Answer 1

For those who are interested, I ended up writing up the variables in config/environments/production.rb & config/environments/development.rb

You can set global variables by adding:

config.fb_app_id = 23839282 
config.fb_app_secret = aj32j32j4jk

(set the appropriate one in production.rb or development.rb)

These can then be used in initialisers, and also in my actual application’s views, controllers, etc.

Rails.configuration.fb_app_id
Rails.configuration.fb_app_secret
