swift 和解析 : Query Results Where Column Class Is Equal To A Column In Users Class

Question

我已经广泛搜索了这个问题的答案。在书面英语中，我正在尝试执行以下操作:

“Issues”类中“WorkGroup”列与“Users”类中“WorkGroup”列相等的查询结果。

我尝试了无数种方法，包括； NotContainedIn、ObjectForKey、wherekey(matchesquery)、includeKey、添加指针等

let query = PFQuery(className: ISSUES_CLASS_NAME)
let now = Date()

query.whereKey(ISSUES_SUB_DATE, lessThanOrEqualTo: now)
query.whereKey(ISSUES_STATUS, notEqualTo: "Closed")
query.order(byDescending: ISSUES_SUB_DATE)

// Add Where Issues WorkGroup value = Users WorkGroup value.

Answer 1

let userQuery = PFUser.query();
// Set up user query
let issueQuery = PFQuery(className:"Issue");
issueQuery.whereKey("WorkGroup", matchesKey:"WorkGroup", inQuery:userQuery);
