在Spree和Rails上包括一个自定义模块

Question

I'm trying to add my module to my class_eval on Spree.

This is located on: lib/spree/core/app/models/spree/payment/processing.rb

Tried with the following:

module Spree
   Payment.class_eval do
     require GatewayError

   end
end

I am trying to include the following located on: lib/spree/error_override.rb

module Spree
  module GatewayError


  end
end

The error I'm getting when I try to load the server is:

`block in <module:Spree>': uninitialized constant Spree::GatewayError (NameError)

Its my first time trying to include my own module to a class, would be awesome if someone can point me in the right direction.

Thank you in advance!

Answer 1

One solution would be to manually require the file during initialization process.

config/initializers/require.rb:

# put here all files that you want to require manually
require "#{Rails.root}/lib/spree/error_override.rb" 

And that's it - your module is now ready to use ;)
