undefined method `beginning_of_month 'for {: date => Wed, 23 Jan 2019}: Hash
如果您试图在
哈希
而不是日期时间
对象上使用月初
方法,请检查日期
变量的赋值。现在我遇到另一个错误:在内容标签中没有给出块(收益)
:td,view.capture(day,&callback),class:day\u类(day)
从捕获
中删除回调
,它看起来是这样的:`content\u标记:td,view.capture(day),class:day\u classes(day)`,但它仍然显示相同的错误,您需要将块
传递给捕获
,让我们来看看。
undefined method `beginning_of_month 'for {: date => Wed, 23 Jan 2019}: Hash
