Ruby on rails Ruby新手strftime时间，现在

我用ruby写了以下内容

t = Time.now
    t.strftime("%Y-%d-%m")

SCHEDULER.every '1m', :first_in => 0 do |job|
  send_event('gmail_gh', {current: gmail.inbox.count(:after => Date.parse(t)), older: gmail.inbox.count})  

但是我得到了这个错误

scheduler caught exception:
can't convert Time into String

我认为这与t变量有关，并且它不是一个tru，我对Ruby是新手，所以我有点卡住了。如果你看一下gem文档，你会发现：after和：before参数以YYYY-MM-DD的格式包含一个日期

从创业板自述：

gmail.inbox.count(:after => Date.parse("2010-02-20"), :before => Date.parse("2010-03-20"))
gmail.inbox.count(:on => Date.parse("2010-04-15"))

您的代码正在传递YYYY-DD-MM，这可能导致错误

编辑

当您在datetime对象上调用strftime时，它不会修改该对象-只返回基于您给定格式的字符串表示法

因此，Date.parse（t）仍然是Time.now参数

试试这个：

t = Time.now.strftime("%Y-%m-%d")
Date.parse(t)

为此，我已将变量编辑为t.strftime（“%Y-%m-%d”），但仍然出现错误
