  if file
    view_path = File.join(Corrupt.app_root, 'views')
    @file = File.join(view_path, file)
  else
    @file = File.join(Corrupt.root, 'public', 'index.haml')
  end
  @layout = File.join(Corrupt.app_root, 'views', 'layouts', 'application.haml')
  @variables = {}
end

Dynamic Method Handling

This class handles dynamic methods through the method_missing method

#method_missing(name, *args) ⇒ Object

This captures any key/value pair called on the Template object and saves them for later use in the rendered template file.
