我有一个控制器：
class StatsController < ApplicationController
require 'time'
def index
@started = "Thu Feb 04 16:12:09 UTC 2010"
@finished = "Thu Feb 04 16:13:44 UTC 2010"
@duration_time = stats_duration(@started,@finished)
end
private
def stats_duration(started,finished)
time_taken = distance_of_time_in_words(Time.parse(started),Time.parse(finished))
time_taken
end
end
它接收开始和结束时间并计算时间之间的持续时间.
当我运行这个时,我收到以下错误：
private method `gsub!’ called for Thu
Feb 04 16:12:09 UTC 2010:Time
为什么会这样？
解决方法
私有方法gsub！在使用Time.parse时调用通常意味着您使用Time对象而不是String调用了parse,因此听起来您的代码实际上是在尝试将时间解析两次.
例如
>> t = Time.now
=> Fri Feb 05 13:12:17 +0000 2010
>> Time.parse(t)
NoMethodError: private method `gsub!' called for Fri Feb 05 13:12:17 +0000 2010:Time
