使用 will_paginate 在 Ruby 中对数组进行分页 [英] Paginating an Array in Ruby with will_paginate

问题描述

我有一个数组@level1，它看起来像这样:

I have an array @level1 which looks like this :

[[3.0, 4, 2], [2.0, 48, 3], [2.1, 56, 4], ............]

我想在这个数组上应用分页，这样每个页面一次只显示几行.我试过这个:

I want to apply pagination on this array such each page displays only a few rows at once. I tried this:

@temp1 = @level1.paginate(:page => params[:page])

但它抛出以下错误:

undefined method `paginate' for [[3.0, 4, 2], [2.0, 48, 3], [2.1, 56, 4]]:Array

如何使用 will_paginate 对此进行分页?

How can I perform pagination on this using will_paginate?

推荐答案

当然，您可以使用 WillPaginate::Collection 来构建跨集合的任意分页.假设一个名为 values 的数组:

Sure, you can use WillPaginate::Collection to construct arbitrary pagination across collections. Assuming an array called values:

@values = WillPaginate::Collection.create(current_page, per_page, values.length) do |pager|
  pager.replace values
end

然后您可以像对待任何其他 WillPaginate 集合一样对待 @values，包括将其传递给 will_paginate 视图助手.

You can then treat @values just like any other WillPaginate collection, including passing it to the will_paginate view helper.
