Haml / Ruby / Rails有条件地添加元素？

Question

我有这段代码：

- userlist.each do |member|
  = render :partial => 'projects/member_small', :locals => { :user => member }

我想每两次添加一个div元素do | member |发生。所以基本上每两次一次。我想要这个：

- userlist.each do |member|
  .row
    = render :partial => 'projects/member_small', :locals => { :user => member }

Answer 1

您可以将列表分成两组：

- userlist.each_slice(2) do |group|
  .row
    - group.each do |member|
      = render :partial => 'projects/member_small', :locals => { :user => member }
