ruby-on-rails - rails : Find tasks that were created on a certain day?

Question

我有一个任务列表(名称、starts_at)，我试图在每日 View 中显示它们(就像 iCal)。

def todays_tasks(day)
    Task.find(:all, :conditions => ["starts_at between ? and ?", day.beginning, day.ending]
end

我不知道如何将 Time.now(例如“2009-04-12 10:00:00”)动态转换为一天的开始(和结束)，以便进行比较。

Answer 1

def todays_tasks(now = Time.now)
  Task.find(:all, :conditions => ["starts_at > ? AND < ?", now.at_beginning_of_day, now.at_end_of_day])
end

瞧!
