Syntax for form_for when building an array from checkboxes

Question

I\'m making a form for an Order object, and the order has many Products, via a join table called OrderProducts. So, we\'ve got something like this:

<% @o

I know the author was looking for version 2 answers, but this is the top hit for google and I though I would update:

One can do this ( I'm using 4.0, don't know how far back it goes ):

<%= form_for @order do |form| %>
  <%= form.collection_check_boxes(:product_ids, Product.all, :id, :labeling_method ) %>
<% end %>
