需要帮助在Rails 3中实现Railscast 198

Question

我一直在尝试实现Ryan Bates Railscast 198到rails 3像4天…至少在晚上，如果你明白我的意思。无论如何，这是我现在的代码:

用户控制器动作(设计设置以显示已批准的不同状态):

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

我的用户#指数

<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 %>

和用户#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

所以我通过谷歌来处理基本问题:fields_for需要一个"="之类的东西。#index显示良好，但如果我选中一个复选框，然后点击edit checked按钮，我会得到以下错误:

ActiveRecord::RecordNotFound in UsersController#update
Couldn't find User with id=edit_individual

有什么想法?Thanks so much

请检查您的路线。rb和控制器代码，因为它与Railscast 198页面上的代码相差很大:http://railscasts.com/episodes/198-edit-multiple-individually

如果你刚开始使用rails，最好是复制它，并调整为使用用户而不是产品。然后通读一遍，试着理解它的作用
