Re: Multiple child models in a dynamic form

Has anyone converted this tutorial to jQuery?

I don't know the equivalent of:

$(this).previous().value = '1'

Re: Multiple child models in a dynamic form

You should check out the railscasts - http://railscasts.com/episodes/196-nest … orm-part-1

What you want and what you need are too often not the same thing!
When your head is hurting from trying to solve a problem, stop standing on it. When you are the right way up you will see the problem differently and you just might find the solution.

Re: Multiple child models in a dynamic form

The jQuery needed in the application.js (or wherever) for Rails 3.x is

function remove_fields(link) {
  $(link).prev("input[type=hidden]").val("1");
  $(link).parent(".fields").hide();
}

function add_fields(link, association, content) {
  var new_id = new Date().getTime();
  var regexp = new RegExp("new_" + association, "g")
  $(link).parent().before(content.replace(regexp, new_id));
}
