Instance Method Details

#initialize(request) ⇒ Object 



38
 
# File 'lib/views/mixin.rb', line 38

def initialize( request ) ; @request = request ; @layout = :default ; end

#render(path, assigns = {}) ⇒ Object

Render the template found in the directory named after this view (snake cased, of course) E.g. App::Views::Gnome.new.render( “stink” ) would look for templates/gnome/stink.<ext>

def render( path, assigns = {} )
  qpath = "#{self.class.basename.snake_case}/#{path}"
  Waves.log.debug "Rendering template: #{qpath}"
  Views.render( :templates / qpath, assigns.merge!( :request => request ))
end

#renderer(path) ⇒ Object

Return the first renderer for which a template file can be found. Uses Renderers::Mixin.filename to construct the filename for each renderer.
