How to change source for a custom rails generator? (Thor)

Question

I\'m making a custom generator that generates a new rails app, and I do it like this

require \'thor\'
require \'rails/generators/rails/app/app_generator\'

c         


        

Answer 1

The source_paths method doesn't work when using AppBuilder. (which is another option to using rails templates). I have a files directory next to the app_builder.rb file that this class is in. I have this working, though it seems there should still be a more elegant way.

tree .
|-- app_builder.rb
|-- files
     `-- Gemfile

class AppBuilder < Rails::AppBuilder

  def initialize generator
    super generator
    path = File.expand_path( File.join( '..', File.dirname( __FILE__ )) )
    source_paths << path
  end

  def gemfile
    copy_file 'files/Gemfile', 'Gemfile'
  end

and then on the console:

rails new my_app -b path_to_app_builder.rb

The dots are required since the ruby file 'app_builder.rb' is slurped up and eval'd after the rails new command changes into the new app directory (I think).
