如何使用 ruby​​ on rails 对记录进行分页? [英] How do I do paging of records with ruby on rails?

问题描述

我想用 ruby​​ on rails 对数据列表进行分页.基本上，我想一次只显示 20 条记录，带有下一步和后退按钮.显示页码链接会很好，但不是必需的.

这样的东西会很好:

<<上一个 1 2 3 4 5 ... 下一个 >>

是否有内置的方法可以在 ruby​​ on rails(或我可以添加的东西)中执行此操作，因此我不必自己编写?

解决方案

有一个插件 will_paginate 可用于在 RoR 中无缝地进行分页.找到以下链接.他们可能会有所帮助.

I want to do paging of lists of data with ruby on rails. Basically, I want to show only 20 records at a time, with next and back buttons. It would be nice, but not required, to show links for the page numbers.

Something like this would be nice:

<< Previous 1 2 3 4 5 ... Next >>

Is there a built in way to do this in ruby on rails (or something I can add) so I don't have to write this myself?

解决方案

There is a plugin will_paginate that can be used to do pagination seamlessly in RoR. Find following links. They might be of some help.

Also I am sure that following railscast by Ryan Bates is going to be an excellent source of understanding. All rails casts are really good and give you deep understanding of basics. http://railscasts.com/episodes/51-will-paginate
