In my gem (myEngine.rb) I have the following code :

require "myEngine/version"
require "myEngine/models/contact"
require 'rails/generators'
module myEngine


 def self.generate_migration

  file_name= "migrationSrc.rb"
  src_path= "myEngine/migration_files/"+file_name
  destination_path=  "db/migrate/"+file_name
  //
  end
end

When I call the method generate_migration I want my gem to copy the migration file to the db/migrate of my application.

Thanks you for your help.

I have a problem with the copy_file method. It seems that it's not defined – NabilaDevelopper Oct 09 '14 at 08:40

@NabilaDevelopper That's because it must be called from inside a class that inherits from `Rails::Generators::Base`. – Unixmonkey Oct 09 '14 at 17:01
Yes I did that. I am on rails 4 – NabilaDevelopper Oct 10 '14 at 15:10
