I've been stuck on this problem for a couple of days now.
I've have some success with Railscasts Episode #198, but that one is for Rails 2. There have been some changes in Rails 3 that make it so the code provided in Episode #198 won't work.
The problem lies within the edit_individual.html.erb:
Original Code (provided by Ryan @ Railscasts):
<% form_tag update_individual_products_path, :method => :put do %>
<% for product in @products %>
<% fields_for "products[]", product do |f| %>
<h2><%=h product.name %></h2>
<%= render "fields", :f => f %>
<% end %>
<% end %>
<p><%= submit_tag "Submit" %></p>
<% end %>
Modified Code (simply changed fields_for to form_for):
<% form_tag update_individual_products_path, :method => :put do %>
<% for product in @products %>
<% form_for "products[]", product do |f| %>
<h2><%=h product.name %></h2>
<%= render "fields", :f => f %>
<% end %>
<% end %>
<p><%= submit_tag "Submit" %></p>
<% end %>
In the new code, each record is placed within a form of their own, all inside one single form (which is the one I only want).
My question is, how can I get the code provided by Railscasts Episode #198 to work in Rails 3?
Here is a link to the Railscast I mentioned: http://railscasts.com/episodes/198-edit-multiple-individually
