如何选择导轨从今天基于数据库created_at数据

Question

如何在轨今天选择基于数据库created_at数据？

例如:

[#<Event id: 1, customer_id: 1, therapist_id: 1, location_id: 1, service_id: 3, walkin: true, cancel: false, cancel_reason: nil, room_id: 5, starts_at: "2014-04-03 21:31:13", stops_at: nil, created_at: "2014-04-14 10:13:52", updated_at: "2014-04-14 10:13:52">, #<Event id: 2, customer_id: 2, therapist_id: 2, location_id: 2, service_id: 2, walkin: false, cancel: false, cancel_reason: nil, room_id: 1, starts_at: "2014-04-05 21:31:13", stops_at: nil, created_at: "2014-04-14 10:13:52", updated_at: "2014-04-14 10:13:52">, #<Event id: 3, customer_id: 1, therapist_id: 2, location_id: 1, service_id: 1, walkin: false, cancel: false, cancel_reason: nil, room_id: 5, starts_at: "2014-04-07 21:31:13", stops_at: nil, created_at: "2014-04-14 10:13:52", updated_at: "2014-04-14 10:13:52">, #<Event id: 4, customer_id: 2, therapist_id: 2, location_id: 2, service_id: 2, walkin: false, cancel: false, cancel_reason: nil, room_id: 1, starts_at: "2014-04-09 21:31:13", stops_at: nil, created_at: "2014-04-14 10:13:52", updated_at: "2014-04-14 10:13:52">, #<Event id: 5, customer_id: 14, therapist_id: 2, location_id: 2, service_id: 1, walkin: true, cancel: false, cancel_reason: "", room_id: 8, starts_at: "2014-04-15 06:47:00", stops_at: "2014-04-15 07:47:00", created_at: "2014-04-15 06:47:14", updated_at: "2014-04-15 06:47:14">]

当我收集基于created_at今天的数据,我得到的结果:

<Event id: 5, customer_id: 14, therapist_id: 2, location_id: 2, service_id: 1, walkin: true, cancel: false, cancel_reason: "", room_id: 8, starts_at: "2014-04-15 06:47:00", stops_at: "2014-04-15 07:47:00", created_at: "2014-04-15 06:47:14", updated_at: "2014-04-15 06:47:14">

如何收集的所有数据,其中数据就在今天created_at在轨？

谢谢你

请试试这个:

Event.where("DATE(created_at) = DATE(?)", Time.now)
