Question

When using the rails generators with an Rails::Engine, it does not seem to pick up any template files that are put into the lib dir. As instructed here

http://guides.rubyonrails.org/generators.html#customizing-your-workflow-by-changing-generators-templates

Right now I have

 lib/templates/rails/scaffold_controller

I have also tried

 lib/my_engine/templates/rails/scaffold_controller

Has anyone else tried this.

Answer 1

It seems that this is not supported for Engines

In a Rails app the Finisher takes care of adding this to the path

module Rails
 class Application
   module Finisher
    include Initializable

    initializer :add_generator_templates do
      config.generators.templates.unshift(*paths["lib/templates"].existent)
    end

 ......

So this must be done in the Engine config in order for this to work.

module MyEngine
  class Engine < ::Rails::Engine
    config.generators.templates.unshift File.expand_path("lib/templates", root)
  end
end

Is this a bug or the desired behaviour?
