每6个滑轨插入每个循环插入标签? [英] Rails each loop insert tag every 6 items?

问题描述

我有X个图像对象，我需要在视图中循环通过这些图像对象，并且想要每6个对象(对于一个画廊)创建一个新的div.

I have X number of image objects that I need to loop through in a view and want to create a new div every 6 objects or so (for a gallery).

我已经看过周期，但是似乎每隔一个记录都会改变.有谁知道一种每6次将代码插入视图中的方法吗?

I have looked at cycle but it seems to change every other record. Does anyone know of a way to insert code into a view every 6 times?

我可能可以使用嵌套循环来做到这一点，但我对此颇为困惑.

I could probably do it with nested loops but I am kinda stumped on this one.

推荐答案

您可以将Enumerable#each_slice与#each结合使用以避免内联计算. each_slice将数组分成n个块，在这种情况下为6.

You can use Enumerable#each_slice in conjunction with #each to avoid inline calculations. each_slice breaks the array into chunks of n, in this case 6.

<% @images.each_slice(6) do |slice| -%>
  <div class="gallery">
    <% slice.each do |image| -%>
      <%= image_tag(image.url, :alt => image.alt) %>
    <% end -%>
  </div>
<% end -%>
