In Rails, where should I define the variable which can be recognized by every layer of Rails stacks.
For example, I would like to have a CUSTOMER_NAME='John'
variable which can be accessed in helper, rake task, controller and model. Where should I define this variable in Rails app?
I am using Rails v2.3.2
In an initializer in /app/config/initializers
all .rb files in here get loaded, I usually create one called preferences.rb for things like this.
