I'm sure some of you are familiar with Ryan Bates' weekly tutorials on
railscasts.com. A few months ago there was a three-part series
(episodes 73-75) about creating/editing multiple models in one form.
I'm trying to achieve the same but not use obtrusive things like
link_to_function.

Mostly this has been easy enough, but I'm not sure how to rewrite the
add_task_link function (which Ryan makes into a helper at the end of
episode 74):

# projects_helper.rb
def add_task_link(name)
  link_to_function name do |page|
    page.insert_html :bottom, :tasks, :partial => 'task', :object =>
Task.new
  end
end

How do I deal with this?

format.js do
  render :update do |page|
    page.insert_html :bottom, :tasks, :partial => 'projects/
task', :object => Task.new
  end
end

The only problem with this is that I've used a remote link, so it's
had to go back to the server, rather than all be done client side as
it was before... is there another way?

There's a few approaches you could take.  The first one would be to
clone one of the previous task chunks and appendChild to the form.  A
nice way to do this is write a behaviour that clones a copy as soon as
the page is loaded (while the form values are still blank) then makes
clones from that as needed.  The second is that you could basically do
what add_task_link does:

Event.addBehavior({
  '#add_task_link:click': function() {
    $('taskform').insert(<%= render(:partial => 'project/task', ...).to_json);
  }
