Create a RailsAdmin custom field

say "Create stub for '#{field_name = name.sub('rails_admin_', '')}' in gem '#{name}'. This may take a while"
run "rm -rf script/ config/ lib/tasks/"
run "rm -rf app/assets app/controllers app/helpers app/mailers app/models"
run "mkdir -p app/views/rails_admin/main"

inside "lib" do
append_file "#{name}.rb", <<-END

require 'rails_admin/config/fields'
require 'rails_admin/config/fields/base'

module RailsAdmin
  module Config
    module Fields
      module Types
        class #{field_name.camelize} < RailsAdmin::Config::Fields::Base
          RailsAdmin::Config::Fields::Types::register(self)
        end
      end
    end
  end
end

RailsAdmin::Config::Fields.register_factory do |parent, properties, fields|
  if properties[:name] == :#{field_name}
    fields << RailsAdmin::Config::Fields::Types::#{field_name.camelize}.new(parent, properties[:name], properties)
    true
  else
    false
  end
end


END
end


say "RailsAdmin field stub generator is done"

This doesn't seem to work with rails 3.2.12 and ruby 2.0.0.
When running this command I get the following error Method Rails::Generators::PluginNewGenerator#name should be public, not private
