下载了插件 mislav-will_paginate-5b0e0b8d7d8c2096c157212447a6f1925f6ae295.tar.gz （aptana中下载的）
解压后把改文件夹放到 test/vendor/plugins/ 下面
members表 id,name,sex 现有10条记录
page_controller.rb

[Copy to clipboard] [ - ]

CODE:

  def index
     @members = Member.find(:all)
     @members = Member.paginate :page => params[:page], :per_page => 3
  end

index.html.erb

[Copy to clipboard] [ - ]

CODE:

<ol>
  <% for member in @members -%>
    <li><%=member.name%></li>
  <% end -%>
</ol>
    <p>Now let's render us some pagination!</p>
    <%= will_paginate @members %>

will_paginate.rb中的paginate 方法不能加载。 为什么？
需不需要在config/environment.rb: 最后加上 require 'will_paginate' 这句话呢？
急啊！！

晕死搞了好久！
