Ruby 对日期和content text 格式化的 helper

 

<% @news.each do |new| %>
    <div class=<%=cycle('news_list_odd_tl', 'news_list_even_tl')%>>
           <a href="/news/<%= new.id%>"><%= new.title %></a>
           <div class="news_date fr"><%= format_time new.created_at %></div>
      </div>
<% end %>

 

 

module ApplicationHelper
  def format_time(time)
    time.strftime("%Y-%m-%d %H:%M")
  end
  def summary(text)
     #truncate(text.gsub(/<\/?[^>]*>/, ""), 100)
     text.gsub(/(<\/?[^>]*>)|(&\w*;)/, "")
  end
end
