Question

我已在this SO post中读到这一点，您可以将any_of与between合并为：

webshop = Webshop.first

webshop.orders.any_of(
  webshop.orders.between(:datetime_pending, [Time.zone.now-7.days, Time.zone.now]).selector, # An error is raised here.
  webshop.orders.between(:datetime,         [Time.zone.now-7.days, Time.zone.now]).selector
)

但是当使用Mongoid 4尝试此查询时，我收到错误：

ArgumentError: wrong number of arguments (2 for 0..1).
/Users/christoffer/project/vendor/gems/ruby/2.0.0/gems/origin-1.1.0/lib/origin/selectable.rb:63:in `between'

/Users/christoffer/project/vendor/gems/ruby/2.0.0/bundler/gems/mongoid-b91705b0ded8/lib/mongoid/relations/referenced/many.rb:412:in `method_missing'

我在这里缺少什么？

根据文档Queryable#between采用哈希（具有范围值的键）。

您是否尝试过传递而不是数组？

webshop = Webshop.first
now = Time.zone.now
seven_days = now - 7.days
webshop_orders = webshop.orders

webshop_orders.any_of(
  webshop_orders.between(datetime_pending: seven_days..now).selector,
  webshop_orders.between(datetime:         seven_days..now).selector
)

如何在Mongoid 4中结合any_of和？
