我正在使用Chronic解析时间,它返回以下错误:

ArgumentError in EventsController#create 

comparison of Date with ActiveSupport::TimeWithZone failed

如何将我的陈述转换为工作?

def set_dates
  unless self.natural_date.blank? || Chronic.parse(self.natural_date).blank?
    # check if we are dealing with a date or a date + time
    if time_provided?(self.natural_date)
      self.date = nil
      self.time = Chronic.parse(self.natural_date)
    else
      self.date = Chronic.parse(self.natural_date).to_date
      self.time = nil
    end
  end

Time.zone 有一个 parse ActiveSupport::TimeWithZone :

>> Time.zone.parse "October 4 1984"
=> Thu, 04 Oct 1984 00:00:00 EDT -04:00

让它和慢性病一起玩,也许 this article 能帮忙吗?例如,如果你要修补 parse_with_chronic ActiveSupport::TimeZone ,然后可以重写方法:

def set_dates
  unless self.natural_date.blank? || Time.zone.parse_with_chronic(self.natural_date).blank?
    # check if we are dealing with a date or a date + time
    if time_provided?(self.natural_date)
      self.date = nil
      self.time = Time.zone.parse_with_chronic(self.natural_date)
    else
      self.date = Time.zone.parse_with_chronic(self.natural_date).to_date
      self.time = nil
    end
  end
end

看这里: TimeWithZone

ActiveSupport::TimeWithZone.new(Chronic.parse(self.natural_date).utc, Time.zone)
