List of Controller Routes in Rails 3?

What I'm trying to do:

I create some controllers, for example:

• Home
• About
• Gallery
• Contact

Now I want to create a navigation au开发者_如何学Pythontomatically. So is there a way to programmatically fetch the list of controllers/actions to build this navigation?

I don't want to fix the navigation everytime I add a controller.

You can try something like this:

HomeController.action_methods.each do |action|
  url_for(:action => action)
end

Here is a one liner that gives you all the controllers based on your routes file. I found I had a nil value, so I added the rescue, then rejected any of those rescued empty ones. The uniq drops any duplicates.

Rails.application.routes.routes.collect { |r| r.defaults[:controller] rescue '' }.reject! { |c| c.empty? }.uniq 

Added a titlecase to make them more suitable for your navigation.

Rails.application.routes.routes.collect { |r| r.defaults[:controller].titlecase rescue '' }.reject! { |c| c.empty? }.uniq 

This is one for only those in an admin namespace.

Rails.application.routes.routes.collect { |r| r.defaults[:controller].titlecase rescue '' }.reject { |c| c.empty? }.uniq.reject { |n| !n.include?('Admin/')  }.map { |i| i.gsub('Admin/', '') }.sort
