Instance Method Details

#component(path, locals = {}, &block) ⇒ Object

Ease use of components by wrapping the partial helper

This allows us to call component(“map”) which will render RogerStyleGuide.components_path/map/_map.html.erb

Calling component(“map/map”) will still work

Also simplifies passing of locals. It’s just the second parameter of the component helper.
