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.

Public Instance Methods

generate_content_class_names ()

Alias for: page_class

page_class ()

Source

# File lib/haml/helpers/action_view_extensions.rb, line 36
def page_class
  "#{controller.controller_name} #{controller.action_name}"
end

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](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

Also aliased as: generate_content_class_names

with_raw_haml_concat () { || ... }

Source

# File lib/haml/helpers/action_view_extensions.rb, line 49
def with_raw_haml_concat
  old = instance_variable_defined?(:@_haml_concat_raw) ? @_haml_concat_raw : false
  @_haml_concat_raw = true
  yield
ensure
  @_haml_concat_raw = old
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?
