一个键上的两个查询约束与解析和Swift [英] Two Query Constraints On One Key with Parse and Swift

问题描述

guys，我试图获取所有的用户名不包括在数组中的PFUsers（ dontShowUsers 。我也想限制查询的变量 name ，这将获得用户名等于用户名搜索的所有用户，但是当我这样做：

guys, I am trying to get all the PFUsers whose username is not included in an array (dontShowUsers. I also want to limit the query with the variable name, which gets all users whose username is equal a name the user searches. However when I do this:

findUsers.whereKey("username",containsString:name)
findUsers.whereKey("username",notContainedIn:dontShowUsers)

每个用户都显示，它执行这两个查询，并将它们加在一起我想约束第一个 whereKey

Every user shows. It peforms both these queries, and adds them together. I want to constrain the first whereKey with the second whereKey. What would be the best way to go about this?

推荐答案

p>这是一种方式

println(geoPoint)
user["location"] = geoPoint
let rejectedUsers: [String] = user["rejected"].copy() as [String]
let acceptedUsers: [String] = user["accepted"].copy() as [String]
let ignoredUsers = rejectedUsers + acceptedUsers

var query = PFUser.query()
query.whereKey("location", nearGeoPoint: geoPoint)
query.whereKey("username", notEqualTo: user.username)
query.whereKey("gender", equalTo: user["interestedIn"])
query.whereKey("username", notContainedIn: ignoredUsers)
query.limit = 10
query.findObjectsInBackgroundWithBlock({
    (objects: [AnyObject]!, error2: NSError!) -> Void in
    if error2 != nil {
        println(error2)
    } else {
        if objects.isEmpty {
            println("empty query")
        } else {
            for object in objects {
                self.usernames.append(object.username)
                self.userImages.append(object["image"] as NSData)

注意我是如何从parse
复制我的用户[rejected创建ignoredUsers

notice how i had to copy my user["rejected"] array from parse then i used + to create "ignoredUsers"

然后我可以使用：

query.whereKey（username，notContainedIn ：ignoredUsers）

query.whereKey("username", notContainedIn: ignoredUsers)
