Ruby数组/包含？/。每个

我在尝试确定如何创建所需的阵列时遇到问题

我有一个数组，看起来像这样：

[“2013-10-01”、“2013-10-02”、“2013-10-07”]

所以有7天，10-01是星期天，10-07是星期一。我想将每个日期转储到它各自的数组中，但是如果日期不存在（10-03），我想在星期二数组中放置一个空元素

代码Ex。

date_数组=[“2013-10-01”、“2013-10-02”、“2013-10-07”]
星期日数组=[]
星期一数组=[]
星期二数组=[]
星期三数组=[]
星期四数组=[]
星期五数组=[]
星期六数组=[]
星期日数组=[]
日期_数组。每个do |日期|
如果日期包括在内？（Date.parse（Time.now.to_s）-39）.strftime（“%Y-%m-%d”）
sunday\u array此程序将按您的要求执行。对于每个员工，它创建一个包含
false
值的七元素数组，然后将
详细信息
数组中每个元素对应的星期几设置为
true
。最后，未工作的天数仍然包含
false

请注意，
Time#wday
为周日返回
0
，为周六返回
6
，因此员工阵列的每个成员从周日到周六

从输出中可以看出，样本数据中的每个员工都从周一工作到周五，除了Ramille Ford，他周五也请假

包含
pp
模块只是为了证明
pp
命令可以很好地布局数据。你不需要它

require 'date'
require 'pp'

更新

Luigi建议使用
groupby
。这个替代版本就是这样写的，我认为它不太可读，但你可能更喜欢它

cards = {}
table['data'].each do |staff|
  name = staff.values_at(*%w/ firstName lastName /).join(' ')
  cards[name] = Array.new(7, false)
  staff['details'].group_by { |clock| Date.parse(clock['date']).wday }.each_key do |wday|
    cards[name][wday] = true;
  end
end


更新2

最后一种选择似乎是按照你最近说的做。如果您的需求再次发生变化，请提出一个新问题，全面解释您的需求，并给出一个实际数据的好例子。我花了几分钟寻找一个不存在的bug：Anisa Martin确实在8:26打卡，8:00打卡

这个迭代与我的原创并不遥远，如果你有足够的知识来为自己写这篇文章，那么很难相信你不会想到同样的事情

cards = {}
table['data'].each do |staff|
  name = staff.values_at(*%w/ firstName lastName /).join(' ')
  cards[name] = Array.new(14, nil)
  staff['details'].each do |clock|
    wday = DateTime.parse(clock['date']).wday
    cards[name][wday + wday, 2] = clock.values_at(*%w/ checkInTime checkOutTime /)
  end
end

为什么要编写如此复杂的代码？：）+1你可以把整个任务都告诉我们，我们会提出更好的解决方案吗？@alex是的。。我同意你的看法。我想你是想用。这肯定更近了，谢谢你的提示。然而，我需要的是一个包含14个值的数组，其中包含每天对应的实际时间（签入、签出、签入、签出等）。我如何提取这些数据？为了澄清我的上述评论，我需要一个类似于您上面的哈希值，其值为签入/签出时间的14个元素数组，与包括真/假的7个元素数组相比。@Luigi:这是新的。我建议您需要一个包含七对时间的数组，每对时间都是该时段的输入和输出时间。你似乎还没有考虑清楚这一点，因为有些员工一天内登录和注销两次<例如，威廉·布朗每天注销两次。您希望如何表示这些数据？@Luigi，您还需要决定是希望报告在之前的七天内运行（在本例中为星期二到星期一），还是如您所说，列始终为星期日到星期六。值得关注的是-对于这些数据的格式，我深表歉意，实际上，在这种情况下，我总是选择晚一点。最终，这些数据将只包括较晚的时间，因此没有人一天签入/签出超过一次。数据将始终在周六晚上运行，从周日到周六，因此列将保持静态。
