# 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

module ActionViewExtensions
# 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](http://sass-lang.com)),
# you could refer to this specific action:
#
# .entry.show
# font-weight: bold
#
# or to all actions in the entry controller:
#
# .entry
# color: #00f
#
# @return [String] The class name for the current page
