Rails 2 to Rails 3 : using link_to instead of link_to_remote (including remote and update)

Question

A quick and easy answer I\'m sure. I\'m upgrading a Rails project from version 2 to version 3 and replacing a load of the link_to_remote with link_to\'s as per the Rails 3

Answer 1

The :update option isn't supported by the new link_to :remote => true.

You will either have to

• use the legacy plugin
• write the JS/AJAX yourself instead of using :remote => true
• use render :update { |page| p.replace_html ... }

Answer 2

The :update parameter is gone. You need to handle the DOM update yourself using Unobtrusive JavaScript. Also, make sure you actually included the csrf_meta_tag helper in your layout.

I wrote an article about using unobtrusive JavaScript in Rails 3.
