检查Ruby中的数组中是否存在created_at值不等于当前日期的值

Question

我有一个user.paid_subscriptions集合，其中每个订阅都有created_at（日期时间）和active（布尔值）属性。

如何检查PaidSubscription是否存在created_at 不等于到某个日期且active是true？

PaidSubscription看起来像这样：

[
  #<PaidSubscription id: 11457,
    user_id: 12,
    period: 3,
    price: 4000,
    expires_at: "2016-03-08 09:44:56",
    expires_at: "2016-03-08 09:44:56",
    created_at: "2015-12-08 09:44:56",
    updated_at: "2016-03-08 23:00:09",
    active: false,
    giver_id: 20573,
    partial: false,
    remaining_days: 0>,
  #<PaidSubscription id: 13948,
    user_id: 12,
    period: 1,
    price: 1500,
    expires_at: "2016-04-11 12:07:40",
    created_at: "2016-03-11 13:07:40",
    updated_at: "2016-04-11 22:00:11",
    active: false,
    giver_id: nil,
    partial: false,
    remaining_days: 0>,
  #<PaidSubscription id: 11458....
]

Answer 1

试试这个，

如果是查询，那么它应该是这样的

user.paid_subscriptions.where("created_at < :date or created_at > :date and active = :active",{date: DateTime.civil(yyyy,mm,dd), active: true})

或者

如果它是一个数组，你可以像下面一样使用它。

user.paid_subscriptions.any? {|ps| ps.active && ( ps.created_at.to_date < Date.civil(yyyy, mm, dd) || ps.created_at.to_date > Date.civil(yyyy, mm, dd))}
