ruby-on-rails - ruby/rails 未定义方法 `DAYNAMES' 用于日期 :Class

Question

我的代码:

<% require 'date' %>
 <% today = Date.today%>
 <% (today..(today+7)).each{ |day| %>
 <a href="#" class="btn btn-large btn-primary disabled"><%=Date::DAYNAMES(day.wday)%> </a>
 <% } %>

我收到错误信息

undefined method `DAYNAMES' for Date:Class

缺少什么？

Answer 1

Date::DAYNAMES 是一个数组，而不是一个方法。来自 the docs :

DAYNAMES An array of string of full name of days of the week in English. The first is “Sunday”.

所以，你想要做的是:

<% require 'date' %>
 <% today = Date.today%>
 <% (today..(today+7)).each{ |day| %>
 <a href="#" class="btn btn-large btn-primary disabled"><%=Date::DAYNAMES[day.wday]%> </a>
 <% } %>
