Ruby on rails 查看将列表拆分为两列的帮助器
我有个小问题 我正在haml视图中呈现定义列表。这是代码Ruby on rails 查看将列表拆分为两列的帮助器,ruby-on-rails,Ruby On Rails,我有个小问题 我正在haml视图中呈现定义列表。这是代码 .col - @product.data.each do |features_group_id, features_group| .data-group %h3= features_group["name"] %dl - features_group['features'].each do |id, hash|
.col
- @product.data.each do |features_group_id, features_group|
.data-group
%h3= features_group["name"]
%dl
- features_group['features'].each do |id, hash|
- if @product.product_category.show_feature_ids.include?(id)
%span.data-wrap
%dt
= hash['name']
%dd
= hash['value']
我必须把这份名单分成两列
我必须取product.data.count/2并在两列中显示这两个块
.col
- @product.data_batch1.each do |features_group_id, features_group|
.data-group
%h3= features_group["name"]
%dl
- features_group['features'].each do |id, hash|
- if @product.product_category.show_feature_ids.include?(id)
%span.data-wrap
%dt
= hash['name']
%dd
= hash['value']
.col
- @product.data_batch2.each do |features_group_id, features_group|
.data-group
%h3= features_group["name"]
%dl
- features_group['features'].each do |id, hash|
- if @product.product_category.show_feature_ids.include?(id)
%span.data-wrap
%dt
= hash['name']
%dd
= hash['value']
有什么简单的解决方案可以做到这一点吗?您可以使用,因为@product.data
是或充当数组
从您的代码:
- @product.data.in_groups_of(2, false).each do |group|
.col
- group.each do |features_group_id, features_group|
.data-group
%h3= features_group["name"]
%dl
- features_group['features'].each do |id, hash|
- if @product.product_category.show_feature_ids.include?(id)
%span.data-wrap
%dt
= hash['name']
%dd
= hash['value']
甚至在这上面也有!:-) 如何分割批次。是上半部分还是下半部分?@emaillenin是的,如果product.data.count是18,则分两批,共9批,如果是13->7+6
