Ruby on Rails - 如何正确映射和链接到新控制器？

Question

I am trying to create this controller:

  def calculate
    # Do some calculations here     


    respond_to do |format|
      format.json{head status}
    end
  end

and I have a HAML file in which I make my HTML and in there I want to link to something like this:

=link_to("stats" , controller_path_url)

where controller_path is a rake routes path that is shown. My question is how do I make this sort of uniquely named controller function to be mapped and show its path when I do rake routes? Is there something I have to do in routes.rb? What should I change there?

Thanks!

Answer 1

You should do smth like following in your routes.rb file:

match 'calculate' => 'controller_name#calculate'

then run:

bundle exec rake routes

and see your path.

It should be calculcate_path for path and calculate_url for full path.

You'll need to modify your routes.rb file. I suggest you check out http://guides.rubyonrails.org/routing.html , it's really extremely helpful.
