Question

I have an action in my controller that renders JSON back to the client:

@data = [{label:"foo", url:"..."}, ...]

render :json => @data

Basically “data” is an array of objects that each have a label and url property. The want to generate the URL on the server-side instead of handing this data to the client and having it iterate over it to generate the URL strings.

If I could use the “link_to” method it would look like this:

link_to “foo”, {:action => ‘some_action’, :foobar => {}}

Basically link to the /foobar/some_action

What’s the best way to generate the URL while in the controller since I don’t have the handy “link_to” method?

Answer 1

Check the method ActionController::Base#url_for

For Rails 3 see ActionDispatch::Routing::UrlFor#url_for
