Rails 3错误信息

我得到了错误DEPRECATION WARNING：error_messages_for已从Rails中删除，现在可作为插件使用。请用rails plugin install git://github.com/rails/dynamic_form.git安装。（在C：/Users/rod/connect-my-friends/app/views/user/register.html.erb：5处从_app_views_user_register_html_erb__195833478_79197384_0调用）Rails 3错误信息

我得到了插件并做了一次耙子，但仍然出现错误我没做对吗？

这里是页面代码的样子

<%= form_for :user do |form| %> 
<fieldset> 
    <legend>Enter Your Details</legend> 
    <%= error_messages_for "user" %> 
    <div class="form_row"> 
    <label for="screen_name">Screen name:</label> 
    <%= form.text_field :screen_name, 
     :size => User::SCREEN_NAME_SIZE, 
     :maxlength => User::SCREEN_NAME_MAX_LENGTH %> 
    </div>

我相信这应该是足够的信息，如果亚需要更多的问我会编辑这个并添加它

require File.expand_path('../boot', __FILE__) 

require 'rails/all' 

# If you have a Gemfile, require the gems listed there, including any gems 
# you've limited to :test, :development, or :production. 
Bundler.require(:default, Rails.env) if defined?(Bundler) 

module ConnectMyFriends 
    class Application < Rails::Application 
    # Settings in config/environments/* take precedence over those specified here. 
    # Application configuration should go into files in config/initializers 
    # -- all .rb files in that directory are automatically loaded. 

    # Custom directories with classes and modules you want to be autoloadable. 
    # config.autoload_paths += %W(#{config.root}/extras) 

    # Only load the plugins named here, in the order given (default is alphabetical). 
    # :all can be used as a placeholder for all plugins not explicitly named. 
    # config.plugins = [ :exception_notification, :ssl_requirement, :all ] 

    # Activate observers that should always be running. 
    # config.active_record.observers = :cacher, :garbage_collector, :forum_observer 

    # Set Time.zone default to the specified zone and make Active Record auto-convert to this zone. 
    # Run "rake -D time" for a list of tasks for finding time zone names. Default is UTC. 
    # config.time_zone = 'Central Time (US & Canada)' 

    # The default locale is :en and all translations from config/locales/*.rb,yml are auto loaded. 
    # config.i18n.load_path += Dir[Rails.root.join('my', 'locales', '*.{rb,yml}').to_s] 
    # config.i18n.default_locale = :de 

    # JavaScript files you want as :defaults (application.js is always included). 
    # config.action_view.javascript_expansions[:defaults] = %w(jquery rails) 

    # Configure the default encoding used in templates for Ruby 1.9. 
    config.encoding = "utf-8" 

    # Configure sensitive parameters which will be filtered from the log file. 
    config.filter_parameters += [:password] 
    end 
end

这是所有新对我所以我加了aplaction.rb文件不知道如何把它放在

检查插件的README

我的猜测是你应该使用form.error_messages而不是error_messages_for "user"。

--edit

其他的猜测：

你有没有重新启动安装后的服务器？
您是否正在加载所有插件？检查config/application.rb - >config.plugins。
