using an array with fields_for

Question

How can I iterate through an array of objects (all the same model) using fields_for ? The array contains objects created by the current_user.

I currently have:

<%= f.fields_for :descriptionsbyuser do |description_form| %>
<p class="fields">
    <%= description_form.text_area :entry, :rows => 3 %>
    <%= description_form.link_to_remove "Remove this description" %>
    <%= description_form.hidden_field :user_id, :value => current_user.id %>
</p>
<% end %>

But I want to replace the :descriptionsbyuser with an array I created in my controller - @descriptionsFromCurrentUser

This is also inside Ryan Bate's "nested_form_for"

Any pointers would be greatly appreciated!

Docs for fields_for clearly shows you the way of using arrays:

Or a collection to be used:

<%= form_for @person do |person_form| %>
  ...
  <%= person_form.fields_for :projects, @active_projects do |project_fields| %>
    Name: <%= project_fields.text_field :name %>
  <% end %>
  ...
<% end %>

@active_projects here is your array.
