在下面的云代码中,我想获得 saveAll 函数的反馈,但是在解析日志页面中从我的客户端调用代码后,我只能看到:
I2014-10-08T15:28:32.930Z] v249: Ran cloud function acceptMeetingBis for user dyGu143Xho with:
Input: {"meetingId":"bUSTGNhOer"}
Result: Meeting accepted
这是我的云代码:
Parse.Cloud.define("acceptMeetingBis", function(request, response) {
var userAcceptingTheMeeting = request.user;
var meetingId = request.params.meetingId;
var changedObjects = [];
var queryForMeeting = new Parse.Query("MeetingObject");
queryForMeeting.equalTo("objectId", meetingId);
queryForMeeting.first({
success: function(meeting) {
var userCreatorOfMeeting = meeting.get("user");
userAcceptingTheMeeting.increment("acceptedMeetings", +1);
changedObjects.push(userAcceptingTheMeeting);
meeting.add("participantsObjectId", userAcceptingTheMeeting.id);
if (meeting.get("participantsObjectId").length === meeting.get("meetingNumberOfPersons")) {
meeting.set("isAvailable", false);
}
changedObjects.push(meeting);
Parse.Object.saveAll(changedObjects, {
success: function(objects) {
console.log("Successfully saved objects"); //this line doesn't show up
response.success("objects saved");
},
error: function(error) {
// An error occurred while saving one of the objects.
response.error(error);
}
});
//future query and push notifications will go here
response.success("Meeting accepted");
},
error: function() {
response.error("Failed to accept the meeting");
}
});
});
我还需要在 saveAll() 之后添加一些推送和另一个嵌套查询,但在执行/尝试之前我想知道这是否是正确的使用方法,或者我是否必须以不同的方式构建代码。我是 javascript 新手,老实说,我正在努力理解一些概念,比如承诺。任何帮助将非常感激。
