I'm following Ryan Bates, Railscast episode 52 and I've translated relevant parts of the code to work with Rails 3.0.0.beta2. In Ryan's case, he simply marks items incomplete and saves a timestamp. If an Item contains a timestamp the model returns the item in the completed list.

I'm attempting to save ALL values true or false, depending on whether the check_box_tag is selected or not (using boolean). I am able to save ONLY selected items, true or false. How can I save an entire list of items true or false, depending on whether the checkbox is selected? The following is my attempt:

controller logic:

 def yardsign
    Add.update_all(["yardsign=?", true], :id => params[:yard_ids])
    redirect_to adds_path
  end

html.erb:

<%= form_tag yardsign_adds_path, :method => :put do %>
<% @adds.each do |add| %>
  <td><%= check_box_tag "yard_ids[]", add.id %></td>
    <% end %>
<% end %>

routes.rb

resources :adds do
    collection do
     put :yardsign 
  end
end

Terminal
