Instance Method Details

#add_routes(*lines) ⇒ Object

Based on the ‘route_resources’ method, but less restrictive. Adds arbitrary lines to the config/routes.rb file.

def add_routes(*lines)
  text = (lines.flatten.map do |line|
    line.strip!
    logger.route line
    "  #{line}\n"
  end).join

  sentinel = 'ActionController::Routing::Routes.draw do |map|'
  unless options[:pretend]
    gsub_file('config/routes.rb', /(#{Regexp.escape(sentinel)})/mi) {|match| "#{match}\n#{text}" }
  end
end

#nested_class_template(relative_source, class_details, template_options = {}) ⇒ Object

A bit like the ‘template’ method, but wraps the rendered template output in a Ruby class definition, potentially nested in one or more module definitions. class_details should be a hash in the form returned by InvoicingGenerator::NameTools#extract_name_details, detailing information about the class and to which file it should be written.
