解析服务器relation.add（）不起作用

Question

问题说明

如果我创建一个关系并使用relation.add（）方法就没有任何反应。

重现的步骤

let Booking = Parse.Object.extend("Booking")
let bookingQuery = new Parse.Query(Booking)
bookingQuery.get(newBookingObject.id, {
success: booking => {

    console.log("invites", invites)
    // prints array of existing ParseObjects from another class

    let relation = booking.relation("invites")
    console.log(relation) 
    // prints new relation with key "invites" and parent "Booking"

    relation.add(invites)
    console.log(relation)
    // prints exactly the same relation object as before - nothing changed

    booking.save().then(res => console.log(res))
    // an empty relation is added
},
error: error => console.log("error", error)
// no errors
})

预期结果

relation.add（arrayOfParseObjects）应该将对象添加到关系

实际结果

什么都没发生

Answer 1

insted of

    relation.add(invites)

请尝试以下

    for (var i =0; i<invites.length;i++){
    relation.add(invites[i])
    }

此致
