Module: Haml::Helpers::ActionViewExtensions

Module | Haml::Helpers::ActionViewExtensions
In: | lib/haml/helpers/action_view_extensions.rb

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.

### Methods

page_class

### Public Instance methods

page_class()

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
