我有一个@ user.photos数组,它会返回类似的内容:
[#<Photo id: 53, photo_file_name: "Freedom-Tower",
photo_content_type: "image/jpeg", photo_file_size: 1937702,
photo_updated_at: "2013-04-23 23:57:22", user_id: 1,
created_at: "2013-04-23 23:57:23", updated_at: "2013-04-23 23:57:23">,
#<Photo id: 52, photo_file_name: "sunset-Courtsey",
photo_content_type: "image/jpeg", photo_file_size: 1937702,
photo_updated_at: "2013-04-23 23:51:22", user_id: 1,
created_at: "2013-04-23 23:51:24", updated_at: "2013-04-23 23:51:24">
我想创建一个条件,检查用户是否最近创建了一张照片
像:@ user.photos.any? {| x | x.created_at btw Time.now ..- 5秒} ??
答案 0 :(得分:8)
您可以使用5.seconds.ago:
@user.photos.any? {|x| x.created_at > 5.seconds.ago }
答案 1 :(得分:3)
怎么样:
@user.photos.any? { |x| x.created_at > (Time.now-5.seconds) }
上限是否有原因?可以在将来制作照片吗?
