pages_controller.rb
@past_challenges_by_years = @past_challenges.group_by { |t| [t.deadline.year, t.deadline.month] }
如何在视图中将其分解为年份,然后将其细分为月份,如下所示:
2014 # Years
01 # Months
Challenge
Challenge
02
Challenge
08
Challenge
2016
03
Challenge
08
Challenge
view.html.erb
<% @past_challenges_by_years.sort.each do |year, challenges| %>
<%= year %>
<%= month %> # I don't know how to define this.
<% for challenge in challenges %>
etc...
<% end %>
<% end %>

我首先对密钥进行排序,然后在迭代这些密钥时查找挑战。

编辑:这是一个只显示年份和月份的新解决方案。
<% @past_challenges_by_years.keys.sort.each do |(year, month)| %>
<%= year %>
<br />
<%= month %>
<br />
<% @past_challenges_by_years[[year, month]].each do |challenge| %>
<%= challenge %>
<br />
我认为转换为ERB应该很简单。
