Need help with implementing Railscast 198 in Rails 3 - ruby-on-rails

Question

I have been trying to implement Ryan Bates Railscast 198 into rails 3 for like 4 days... at least at night if you know what I mean. Anyway, here is the code I have right now:
User controller actions (Devise setup to show the different states of approved):
def index
if params[:approved] == "false"
#users = User.find_all_by_approved(false)
elsif
#users = User.find_all_by_approved(true)
else
#users = User.all
end
end
def update
#user = User.find(params[:id])
respond_to do |format|
if #user.update_attributes(params[:user])
format.html { redirect_to root_path flash[:notice] = "User was successfully updated." }
else
format.html { render :action => "edit" }
end
end
end
def edit_individual
#users = User.find(params[:user_ids])
end
def update_individual
#users = User.update(params[:users].keys, params[:users].values).reject { |p| p.errors.empty? }
if #users.empty?
flash[:notice] = "Users updated"
redirect_to users_url
else
render :action => "edit_individual"
end
end
end
My User#index
<h1> Users</h1>
<%= link_to "All Users", :action => "index" %> |
<%= link_to "Users awaiting approval", :action => "index", :approved => "false"%>
|
<%= link_to "Approved Users", :action => "index", :approved => "true" %>
<%= form_tag edit_individual_users_path, :method => :put do %>
<table>
<tr>
<th>Email Address</th>
<th>Approved</th>
<th></th>
</tr>
<% for user in #users %>
<tr>
<td> <%= user.email %></td>
<td><%= check_box_tag user.id %></td>
<td> <%= link_to "Edit", edit_user_path(user) %></td>
</tr>
<% end %>
<p><%= submit_tag "Edit Checked" %></p>
</table>
<% end %>
And the User#edit_individual
<%= form_tag update_individual_users_path, :method => :put do %>
<% for user in #users %>
<%= fields_for "users[]", user do |f| %>
<h2><%=h user.name %></h2>
<p><%= check_box_tag user.id %></p>
<% end %>
<% end %>
<p><%= submit_tag "Submit" %></p>
<% end %>
routes.rb
devise_for :users
resources :users do
collection do
post :edit_individual
put :update_individual
end
end
end
So I handled the basic by googling: fields_for needs an "=" stuff like that. #index shows fine but if I check a checkbox and then hit the edit checked button I get the following error:
ActiveRecord::RecordNotFound in UsersController#update
Couldn't find User with id=edit_individual
Any ideas??? thanks so much

Please check your routes.rb and controller code, as it's quite a bit off from the code on Railscast 198's page: http://railscasts.com/episodes/198-edit-multiple-individually
It's best to just copy it in if you're new to rails and adjust for using users instead of products. Then go through it to try to understand what it does.
