我最近在我的开发博客上安装了will_paginate gem,但我遇到了麻烦.我把它添加到我的gemfile中:

gem 'will_paginate'

然后将它送入帖子控制器:

def index
  @posts = Post.paginate(:per_page => 5, :page => params[:page], :order => 'created_at DESC')

  respond_to do |format|
    format.html # index.html.erb
    format.json { render json: @posts }
    format.atom
  end
end

最后进入视图:

 <div id="post" style="background-color: gray; border-radius: 20px; border-bottom: solid    black 2px; padding-bottom: 40px; padding-top: 40px; margin: auto;">
    <%= post.content.html_safe %>
 </div>
<br />
<div style="padding-bottom: 40px; background-color: brown;">
    <li>Posted:&nbsp;&nbsp;<%= post.created_at.to_formatted_s(:long) %></li>
    <li>Author:&nbsp;&nbsp;<%= post.author_name %></li>
    <li>Comments:&nbsp;&nbsp;<%= post.comments.count %></li>
</div>
<br />
<br />

<%= will_paginate @posts %> …
