Question

I’ve got a collection_select instance in a form, and I’m wondering if it’s possible to have two or more instances in the same form. They’d be built from the same model, and they would save as if they were checkboxes constructed in an Article.all.each loop. To have these work

<%= f.collection_select("article_ids", Article.where(:page => 1), :id, :name) %>
<%= f.collection_select("article_ids", Article.where(:page => 2), :id, :name) %>
<%= f.collection_select("article_ids", Article.where(:page => 3), :id, :name) %>

in the form is pretty much what I’m after. It’s essentially a multiple select but spread over a couple of selects. The field already accepts multiple results, but when I save the form as it is above it only records the option from the final select. Any thoughts?

Cheers!

I just went with checkboxes to solve this, because it’s truly the stuff of nightmares.

<% @articles.each do |a| %>
  <%= check_box_tag("doc[article_ids][]", a.id, @doc.articles.include?(a.id), :class => "article_chooser") %> <a id="<%= a.id %>" class="name"><%= a.name %></a><br />
<% end %>
