为什么搜索结果的分页不起作用？

骑在前一个问题上： Ruby on rails – 搜索结果的分页

这是我的模特：

def self.search(title, company, location_id) if location_id.present? paginate :conditions => ['title LIKE ? AND company LIKE ? AND location_id = ?', "%#{title}%", "%#{company}%", location_id].last(200), :page => @page, :per_page => 20, :order => "total DESC" else paginate :conditions => ['title LIKE ? AND company LIKE ?', "%#{title}%", "%#{company}%"].last(200), :page => @page, :per_page => 20, :order => "total DESC" end end 

当我点击第2页时，url显示：

.../search?company=&location_id=&page=2&title=&utf8=%E2%9C%93

并且页面显示第1页结果..

怎么了？

Answer 1

我认为问题出在这个地方:page => @page 。 变量@page ？ 当您调用Post类的search方法时，您可能应该发送此变量

在模型中：

 def self.search(title, company, location_id, page) if location_id.present? paginate :conditions => ['title LIKE ? AND company LIKE ? AND location_id = ?', "%#{title}%", "%#{company}%", location_id].last(200), :page => page, :per_page => 20, :order => "total DESC" else paginate :conditions => ['title LIKE ? AND company LIKE ?', "%#{title}%", "%#{company}%"].last(200), :page => page, :per_page => 20, :order => "total DESC" end end 

在控制器中：

 def search ... page = params[:page] @posts = Post.search(title, company, location_id, page); end 

Answer 2

在模型中：

 def self.search(title, company, location_id, page) ... :page => page, ... end 

在控制器中：

 def search ... page = params[:page]; @posts = Post.search(title, company, location_id, page); end
