ruby on rails route params in controller

Question

routes.rb:

match 'first/#!/:name' => 'first#first'

first_controller.rb:

class FirstController < ApplicationController
  def first
    @name = params[:name]
  end
end

But the @name variable is nil when I render the url: http://localhost:3000/first/#!/sayuj

Please help

Hash-bang URLs are usually used by JavaScript for routing, not for server-side routing. Why are you doing it like that? — Skilldrick

I agree with Skilldrick. I think there is some XY syndrome going on here. Can you elaborate as to why you need to use hashbang URLs? — Caley Woods

Anything after the first # in the URL is not (usually) sent back to the server; it's used on client side only.

So the URL http://localhost:3000/first/#!/sayuj in the client will actually call the URL http://localhost:3000/first/ on server side.

Jits is correct that the # in the url will drop the rest of the url, also, I believe your route is incorrect, it should look like:

match 'first/:name', :to => 'first#first'

documentation is at Engine yard rails 3 routes.

Rails 3 routing supports shorthand that will let his existing code work. Saying match 'first/:name' => 'first#first' is fine. Also if he were using a name method in FirstController the other shorthand method could be used to say simply: match 'first/name' and rails with link it up accordingly.

Thanks for the info, I did not know you could shorthand that even further.
