对嵌套指针的解析查询？
对嵌套指针的解析查询？
提问于 2015-03-29 22:08:16
我试图对对象中的嵌套指针运行一个查询。根据docs，当查询中包含嵌套指针时，支持点标记，但这似乎不起作用。它不会返回state == %@ AND event.expirationDate > %@
let predicate = NSPredicate(format: "to == %@ AND (state == %@ OR (state == %@ AND event.expirationDate > %@))",
User.currentUser(),
EventInvitation.State.Accepted.rawValue,
EventInvitation.State.Pending.rawValue,
NSDate())
let query = EventInvitation.queryWithPredicate(predicate)
query.includeKey("event")
query.includeKey("from")回答 1

我就是这样解决这个问题的
let acceptedQuery = EventInvitation.query()
.whereKey("state", equalTo: EventInvitation.State.Accepted.rawValue)
.whereKey("to", equalTo: User.currentUser())
let pendingQuery = EventInvitation.query()
.whereKey("state", equalTo: EventInvitation.State.Pending.rawValue)
.whereKey("event", matchesQuery: Event.query().whereKey("expirationDate", greaterThan: NSDate()))
.whereKey("to", equalTo: User.currentUser())
let finalQuery = PFQuery.orQueryWithSubqueries([acceptedQuery, pendingQuery])
.includeKey("from")
.includeKey("event")页面原文内容由Stack Overflow提供。腾讯云小微IT领域专用引擎提供翻译支持
