Rails 3 Edit Multiple Records in a Single Form

editing, forms, railscasts, ruby-on-rails-3

Solution

I found the solution. Just need to modify the following line in the code provided by Ryan @ Railscasts:

<% fields_for "products[]", product do |f| %>

and change it to:

<%= fields_for "products[]", product do |f| %>

Notice, that the `<%` has been modified to `<%=`.

final solution:

<% form_tag update_individual_products_path :method => :put do %>  
  <% for product in @products %>  
    <%= fields_for "products[]", product do |f| %>  
      <h2><%= h product.name %></h2>  
    <% end %>  
  <% end %>  
  <p><%= submit_tag "Submit" %></p>  
<% end %>

I was wondering if anyone could explain this solution to me. From what I understand you should only need a `<%` in front of the `fields_for`.

Problem

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 Thank You, c.allen.rosario
