Rails3：适当使用路由和资源

Question

I've recently joined the world of Rails app development (Rails3) and I may be abusing resourceful routing.

The default resourceful routing makes some really convenient helper methods for the URLs which I use constantly. My problem is that I have controllers that I specified the routing as resourceful simply to take advantage of those helper methods. I have some basic site navigation that has no business with resources.

resource :home do
  member do
    get 'main'
    get 'about'
    get 'login'
    get 'help'
  end
end

Is there a better way to do what I've been doing? Anything that doesn't require that I manually add routing entries each time I have a new controller action?

Just to clarify, I want to specify routing for a controller without having to explicitly add any new actions but I also want it to auto-generate helper methods. So far, I have to explicitly add routes for each action I want that for. I can get something similar by doing this (in a non-resourceful way),

match 'home/about' => 'home#about'

But I don't want to have to write that very every route that doesn't fall into the convention.

Answer 1

Here's another simpler one. Just add a generic route to the bottom of your routes.rb

match ":controller/:action"

and it will map directly to the specified action of the specified controller. You can be a bit more specific if you like. For example, using get instead of match to restrict to HTTP GET requests, specifying the applicaple controllers etc.

get ":controller/:action", :constraints => { :controller => /home|help/ }

Answer 2

You can look into your controller for public instance methods and generate routes automatically.

# routes.rb
HomeController.public_instance_methods(false).select{|m| !(m.to_s =~ /^_/)}.each do |m|
  match "home/#{m}", :action => m, :controller => HomeController, :as => "home_#{m}"
end

This will take the explicit(non-inherited) public instance methods from your controller, and select the ones that don't begin with an underscore(because underscored ones are generated methods for filters, the rest are actual actions). Then it will generate a named route for each.

Keep in mind that routes.rb is processed only at server startup so you will have to restart the server after you add new actions.
