#generate ⇒ Object
Generates a path from routes, returns [path, params]. If no route is generated the formatter will raise ActionController::UrlGenerationError

# File 'lib/action_dispatch/routing/route_set.rb', line 612 def generate @set.formatter.generate(:path_info, named_route, , recall, PARAMETERIZE) end |
#normalize_action! ⇒ Object
Move ‘index’ action from options to recall

# File 'lib/action_dispatch/routing/route_set.rb', line 604 def normalize_action! if @options[:action] == 'index' @recall[:action] = @options.delete(:action) end end |
#normalize_controller! ⇒ Object
Remove leading slashes from controllers

# File 'lib/action_dispatch/routing/route_set.rb', line 599 def normalize_controller! @options[:controller] = controller.sub(%r{^/}, '') if controller end |
#normalize_controller_action_id! ⇒ Object
This pulls :controller, :action, and :id out of the recall. The recall key is only used if there is no key in the options or if the key in the options is identical. If any of :controller, :action or :id is not found, don’t pull any more keys from the recall.

# File 'lib/action_dispatch/routing/route_set.rb', line 556 def # If an explicit :controller was given, always make :action explicit # too, so that action expiry works as expected for things like # # generate({controller: 'content'}, {controller: 'content', action: 'show'}) # # (the above is from the unit tests). In the above case, because the # controller was explicitly given, but no action, the action is implied to # be "index", not the recalled action of "show". if [:controller] [:action] ||= 'index' [:controller] = [:controller].to_s end if .key?(:action) [:action] = ([:action] || 'index').to_s end end |
