将变量添加到config / development.rb rails引擎

Question

Currently confused on configuring my application. I'm currently trying to initialize a new object in config/development.rb

following this sample app tutorial https://www.wepay.com/developer/resources/wefarm-tutorial

My problem is I'm building the application the modular way. where everything sits in engines. The wepay gem is currently installed within the core engine of the application. I'm confused on itializing the new WePay object.

I keep getting the error uninitialized constant Wepay

can someone maybe help to see what I'm doing wrong, am I missing a step since my application is being built within engines instead of Monolithic ?

Any thoughts or help would be great

If you wish to use an initializer - code that should run before the engine is loaded - the place for it is the config/initializers folder.

http://guides.rubyonrails.org/engines.html

Rails will require every file in the config/initializers directory as part of the initialization process - when you mount an engine rails will also look in the engines config/initializers directory.

# config/initializers/we_pay.rb
# Note that globals are not thread safe. 
$wepay = WePay::Client.new(
  ENV['WEPAY_CLIENT_ID'],
  ENV['WEPAY_CLIENT_SECRET'],
  true
)
