More commonly accessed in the initializer via its call to +configuration.admin+.
Returns the AdminUI singleton, giving get-and-set access to the tabs and partial-sets it defines.

This method is always called during initialization, either as a default or to check that specified extensions are

Returns an alphabetical list of every extension found among all the load paths and bundled gems. Any plugin or

def default_controller_paths


Overrides the Rails::Initializer default to look for controllers in TRUSTY_CMS_ROOT rather than Rails.root. 
def default_controller_paths
  [File.join(TRUSTY_CMS_ROOT, 'app', 'controllers')]

def default_extension_paths


In test mode we also add a fixtures path for testing the extension loader.
There are no vendor/* directories in +TRUSTY_CMS_ROOT+ any more but the possibility remains for compatibility reasons.
TrustyCms.root/vendor/extensions
Rails.root/vendor/extensions
Sets the locations in which we look for vendored extensions. Normally:

  env = ENV["RAILS_ENV"] || Rails.env
  paths = [Rails.root + 'vendor/extensions']
  paths.unshift(TRUSTY_CMS_ROOT + "/vendor/extensions") unless Rails.root == TRUSTY_CMS_ROOT
  paths.unshift(TRUSTY_CMS_ROOT + "test/fixtures/extensions") if env =~ /test/
  paths

def default_plugin_paths


Overrides the Rails::Initializer default to add plugin paths in TRUSTY_CMS_ROOT as well as Rails.root. 
def default_plugin_paths

def default_view_path


Overrides the Rails::Initializer default to look for views in TRUSTY_CMS_ROOT rather than Rails.root.

A LoadError is raised if any of the specified extensions can't be found.

config.extensions = [:dashboard, :blog, :all, :comments]
config.extensions = [:dashboard, :blog, :all]
config.extensions = [:layouts, :taggable, :all]
It can include an :all marker to mean 'everything else' and is typically set in environment.rb:
Sets the list of extensions that will be loaded and the order in which to load them.
