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.
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
@return [String] The class name for the current page
# File lib/haml/helpers/action_view_extensions.rb, line 34 34: def page_class 35: controller.controller_name + " " + controller.action_name 36: end
Treats all input to \{Haml::Helpers#haml_concat} within the block as being HTML safe for Rails’ XSS protection. This is useful for wrapping blocks of code that concatenate HTML en masse.
This has no effect if Rails’ XSS protection isn‘t enabled.
@yield A block in which all input to `haml_concat` is treated as raw. @see Haml::Util#rails_xss_safe?
