Question

我正在使用jquery.pageless来实现无限滚动。

向下滚动时会出现错误：GET http://localhost:3000/search?page=2 500 (Internal Server Error)，有时为GET http://localhost:3000/search?page=2 404 (Page Not Found)

search_controller.rb

require 'resque'
require 'will_paginate/array'

class SearchController < ApplicationController
  def index
    @blog = Blog.where(:name => params[:name])
    if(@blog.nil?)
      Resque.enqueue(HardWorker, params[:name])
    end
    search
  end

  def search
    @search = Post.paginate(:per_page => 10, :page => params[:page], :order => ('created_at DESC'))
    if request.xhr?
      sleep(3)
      render :partial => 'search/post'
    end
  end
end

search.html.erb

<%= render(:partial => "post", :collection => @search) %>

<%= will_paginate @search %>
<%= pageless(@search.total_pages, search_path) %>

_post.html.erb

<div style="margin-bottom:3em">
  <h2><%= post.name %></h2>
</div>

模型/ Post.rb

class Post
  include Mongoid::Document
  include Mongoid::Pagination
  store_in collection: "post", database: "post"
  field :_id
  field :blog_id, type: String
  field :name
end

我在rails服务器上实现了一些东西：

Started GET "/search?page=2" for 127.0.0.1 at 2013-09-05 13:06:04 +0100
Processing by SearchController#search as HTML

Completed 500 Internal Server Error in 3012ms

ActionView::Template::Error (undefined method `[]'for nil:NilClass):
    1: <div style="margin-bottom:3em">
    2:   <h2><%= post[:name] %></h2>
    3: </div>
  app/views/search/_post.html.erb:2:in _app_views_search__post_html_erb___963015535_21281256
  app/controllers/search_controller.rb:20:in search

这是第一次显示前10个结果。但是当我向下滚动500内部服务器错误时出现。有人可以帮我解决这个问题吗？谢谢！

will_paginate和jquery.pageless 404页面未找到nd 500内部服务器错误
