Module | Haml::Helpers::ActionViewExtensions |

This module contains various useful helper methods that either tie into ActionView or the rest of the ActionPack stack, or are only useful in that context. Thus, the methods defined here are only available if ActionView is installed.
Returns a value for the "class" attribute unique to this controller/action pair. This can be used to target styles specifically at this action or controller. For example, if the current action were EntryController#show,
%div{:class => page_class} My Div
would become
<div class="entry show">My Div</div>
Then, in a stylesheet (shown here as Sass), you could refer to this specific action:
.entry.show :font-weight bold
or to all actions in the entry controller:
.entry :color #00f
