Question

我想使用云代码有条件地更新几个Parse.Objects。如果该选项适用于相关用户，该函数应该将选择数据保存到新列。

我在第一个Cloud Code功能中遇到了一些严重的问题。我想我的大部分都是正确的，但我一直在成功/错误被称为错误。

我使用以下代码：

Parse.Cloud.define("someFunction", function(request, response) {

var user = Parse.Object.extend("User");
var query = new Parse.Query(Parse.User);
var Table1 = Parse.Object.extend("Table1");
var table1Query = new Parse.Query(Table1);
var Table2 = Parse.Object.extend("Table2");
var table2Query = new Parse.Query(Table2);

var Ids = req.body //this is an array of Parse.Object Ids

var array = [];

var x = Ids.length

while (x--){
var Id = Ids[x];

table1Query.equalTo("user", {__type: "Pointer", className: "_User",                                                                              
                             objectId: Id});
table1Query.find({
success: function (results) {
         var resultIds = _.map(results, function (n) {
                           return n.id});

         var resultObjs = _.map(results, function (n) {
                           return return _.extend(_.find(n), {id: n.id})});

var a = resultIds.length
while (a--) {
var resultId = resultIds[a];

table2Query.equalTo("user", {__type: "Pointer", className: "_User",                                                                              
                             objectId: resultId});
table2Query.find({
success: function (items) {
var MA = _.map(_.flatten(items), function (n) {
return _.find(n)});

var step3 = _.map(resultObjs, function (n) {return _.extend(n, {
Matched: _.filter(MA, function (a) {return a.result.id == n.id})})});

var total = Math.round(_.reduce(_.map(step3, function (n) {return n.Bill
}), function (memo, num) {return memo + num;}, 0) * 100) / 100;

var duty = function (total, id) {
var promise = new Parse.Promise();
table2Query.get(id, {
success: function (Answer) {
Answer.set("duty", total);
Answer.save().then(function (difresult) {
response.success(difresult);
}, function (error) {
response.error(error);})
}
});
}
    array.push(duty(Answer, Id))
    }
})
}
}
})
}
return Parse.Promise.when(array);
})

我希望有一天这对某人有帮助。代码的答案/差异在最后找到，因为我添加了。然后把响应.sccess /错误：

Parse.Cloud.define("someFunction", function(request, response) {

var user = Parse.Object.extend("User");
var query = new Parse.Query(Parse.User);
var Table1 = Parse.Object.extend("Table1");
var table1Query = new Parse.Query(Table1);
var Table2 = Parse.Object.extend("Table2");
var table2Query = new Parse.Query(Table2);

var Ids = req.body //this is an array of Parse.Object Ids

var array = [];

var x = Ids.length

while (x--){
var Id = Ids[x];

table1Query.equalTo("user", {__type: "Pointer", className: "_User",                                                                              
                             objectId: Id});
table1Query.find({
success: function (results) {
         var resultIds = _.map(results, function (n) {
                           return n.id});

         var resultObjs = _.map(results, function (n) {
                           return return _.extend(_.find(n), {id: n.id})});

var a = resultIds.length
while (a--) {
var resultId = resultIds[a];

table2Query.equalTo("user", {__type: "Pointer", className: "_User",                                                                              
                             objectId: resultId});
table2Query.find({
success: function (items) {
var MA = _.map(_.flatten(items), function (n) {
return _.find(n)});

var step3 = _.map(resultObjs, function (n) {return _.extend(n, {
Matched: _.filter(MA, function (a) {return a.result.id == n.id})})});

var total = Math.round(_.reduce(_.map(step3, function (n) {return n.Bill
}), function (memo, num) {return memo + num;}, 0) * 100) / 100;

var duty = function (total, id) {
var promise = new Parse.Promise();
table2Query.get(id, {
success: function (Answer) {
Answer.set("duty", total);
Answer.save().then(function (difresult) {
response.success(difresult);
}, function (error) {
response.error(error);})
}
});
}
    array.push(duty(Answer, Id))
    }
})
}
}
})
}
return 

Parse.Promise.when(array).then(function() {
    response.success("Successfully retrieved Total Bills.");
},
    function(error) {
        response.error("Something is still wrong");
        console.log(error);
    });;
    })

解析云代码错误：Parse.Error {代码：141，消息：“未成功/错误未调用”}
