SAPUI5 odata.v2.ODataModel Call back of batch request is invoked before batch request is complete

I'm having a little issue with my batch request, when the odata model is submitted and triggered, the that.readAndUpdateSercicePeriodPlans(oService).then(function(oSerciceO) in the callback is triggered before the batch return the result
As you can see using my debugger, the call back function is triggered :
but the network didn't return the result yet :
Below is the code, what I am doing wrong? :
odataMod = this.getModel("Service");
odataMod.setUseBatch(true);
var aDeffGroup = odataMod.getDeferredGroups();
//add your deffered group
aDeffGroup.push("deletionGroup");
_.forEach(periodPlanArr, function(periodPlanToDel) {
odataMod.remove('/ProjectTaskServicePeriodPlanCollection(\'' + periodPlanToDel.ObjectID + '\')/', {
groupId: "deletionGroup"
});
});
oGlobalBusyDialog.setText("Deleting Period Plans in progress");
oGlobalBusyDialog.setTitle("Updating data Model");
oGlobalBusyDialog.open();
//This trigger the batch request
odataMod.submitChanges({
// deffered group id
groupId: "deletionGroup",
success: function(oData) {
sap.m.MessageToast.show(oData.toString());
var aErrorData = sap.ui.getCore().getMessageManager().getMessageModel();
var msg = aErrorData.getData();
var oService = _.find(oNoneAssignedTaskModelData, function(oSewrv) {
return oSewrv.ObjectID === uniqueByID[0].ParentObjectID;
});
oGlobalBusyDialog.setText("Updating oModel in progress");
oGlobalBusyDialog.setTitle("Updating data Model");
// ISSUE : This below function is invoked before even the batch request is complete , why ?!
that.readAndUpdateSercicePeriodPlans(oService).then(function(oSerciceO) {
oGlobalBusyDialog.close();
//Logic USER STORY 3423: Get Internal Indicator PeriodPlan and update the employee nternal Indicator PeriodPlan
},
error: function(oError) {
var oResponse = JSON.parse(oError.response.body);
sap.m.MessageToast.show("Fehler: " + oResponse.error.message.value);
}
});

Your Chrome Filter icon will only be red if there is some value in the filter.:)

After debugging all night and drinkind redbull I've finally found the issue :
var aDeffGroup = odataMod.getDeferredGroups();
aDeffGroup.push("deletionGroup");
//I must set the deffered groups after pushing the ID or else it won't be added
this.setDeferredGroups(aDeffGroup);
I'd recommand to avoid adding same group twice - I had some issues because of that.
odataMod = this.getModel("Service");
odataMod.setUseBatch(true);
//var aDeffGroup = odataMod.getDeferredGroups();
//aDeffGroup.push("deletionGroup");
that.setModelDeferredGroup(odataMod, "deletionGroup");
// the function
setModelDeferredGroup: function (oModel, sGroup) {
if (oModel && sGroup) {
var aDeferredGroups = oModel.getDeferredGroups();
if (aDeferredGroups.indexOf(sGroup) < 0) {
aDeferredGroups.push(sGroup);
oModel.setDeferredGroups(aDeferredGroups);
}
}
}

Angular JS: value not updated after assignment

I have a scope that is not updated after assignment inside a factory http call.
var form = {}
var requestForm = {}
requestForm['name'] = $scope.brand.name;
requestForm['country'] = $scope.brand.countryCode;
So I'm setting a $scope.mergeId as my initializer as value 0, then the tableFactory.setMergeRequest will call a http call in the factory file and will return an object, with a boolean and an id #.
$scope.mergeId = 0;
//set merge request/id
tableFactory.setMergeRequest(requestForm).then(function(data){
if(data.mergeRequestStatus){
console.log(data);
$scope.mergeId = data.insertedRequestId; //456
}else{
console.log('no merge id');
}
});
form['mergeId'] = $scope.mergeId;
The boolean will be true, and it should assign the id (456) to the $scope.mergeId. Then that scope will be used to assign the form['mergeId'] variable that will be used in another http call.
When I check the console, the form variable is at zero so it's not updated. I took out the initializer but then it's saying is undefined. The http call is sending back data, it's just the scope is not being updated.
Has anyone gone through this issue before? Should I change the setup for this http call? I tried to this, but it's not setting the right value, it's setting an object.
form['mergeId'] = tableFactory.setMergeRequest(requestForm).then(function(data){
if(data.mergeRequestStatus){
return data.insertedRequestId
}else{
return null
}
});
the response I got from this way, is a d, how do i get the value?
Please help, I've been stuck with this issue for a while. Your help will be appreciated.
ADDITIONAL INFO
This is the http call where tableFactory.setMergeRequest is triggered.
var setMergeRequest = function(object){
var mergeRequestCall = {
method: 'POST',
url: CONFIG.PYTHON_API_END_POINT + '/api/mergerequest',
data: object
}
var d = $q.defer();
$http(mergeRequestCall)
.success(function(response){
d.resolve(response);
}).error(function(response){
d.resolve([]);
});
return d.promise;
}
The response is :
{
"insertedRequestId": 456,
"mergeRequestStatus": true
}

You should set the value where the promise is resolved, not set the value to the function
tableFactory.setMergeRequest(requestForm).then(function(data){
if(data.mergeRequestStatus){
form['mergeId'] = data.insertedRequestId;
}else{
form['mergeId'] = null;
}
});

How to extract data from array in javascript

I have an object (array type) ,its console representation looks like following image . please see the image
This array is created by restangulr using following code ,
restangularProvider.addResponseInterceptor(function (data, operation, what, url, response, deferred) {
if (operation == "getList") {
var extractedData;
extractedData = data.result;
extractedData.paginginfo = data.paginginfo;
return extractedData;
}
if (operation != "get") {
var item = { status: response.status };
feedBackFactory.showFeedBack(item);
}
return response.data;
});
How can I read the elements from this array, I want to extract properties like paginginfo ,also object collection
// The EDIT :1 js libraries I used here angularjsu 1.3.4, and restangular 1.4
My app.js : here I configured rest angular provider
restangularProvider.addResponseInterceptor(function(data, operation, what, url, response, deferred) {
if (operation == "getList") {
var extractedData;
extractedData = data.result;
extractedData.paginginfo = data.paginginfo;
return extractedData;
}
if (operation != "get") {
var item = {
status: response.status
};
feedBackFactory.showFeedBack(item);
}
return response.data;
});
// according to my knowledge this function will intercept every ajax call (api calls) and modify the response , unfortunately I need to apply custom modification because the getlist method must return collection but my api returning object, so according to restangular ,the above code is the possible solution, and here its fine its fetching the data.
userservice.js : this is angular service which using restangular
function(restangular) {
var resourceBase = restangular.all("account");
this.getUsers = function(pagenumber, recordsize) {
var resultArray = resourceBase.getList({
page: pagenumber,
size: recordsize
}).$object;
};
};
according to my knowledge .$object in restangulr resolve the promise and bring back the data, also I am getting the resultArray its looks like in the image in the console, here I can log this array so I think I got all the data from server and filled in this object. I applied some array accessing techniques available jquery and JavaScript like index base accessing , associate accessing but I am getting undefined ie.
resultArray[1] //undifiend;

In angular you can use angular.forEach(items, function(item){ //your code here});
Where items is the array you want to traverse.
If you want to access to one specific position use [], for example var item= items[5].
Then you can do item.property.
UPDATE
Your problem is that you are setting properties in an Array JS Object:
extractedData.paginginfo = data.paginginfo;
You should return the object data like it is and in your controller do something like:
var results= data.result;
var pagInfo= data.paginationInfo;
angular.forEach(results,function(result){});

It looks like the array is numerically indexed (0..1..5); you should be able to simply iterate through it using ForEach (in Angular) or .each (in Jquery).
Something like (JQuery):
$.each(array, function(key, value)
{
// key would be the numerical index; value is the key:value pair of the array index's element.
console.log(value.firstname); // should print the firstname of the first element.
});

First of all, as I said in the comments, you shouldn't be attaching named properties to arrays. Return an object thact contains what you need:
if (operation == "getList") {
return { values: data.result, paging: data.pagingInfo };
}
The getList() method returns a promise, so you need to use that:
this.getUsers = function(pagenumber, recordsize) {
resourceBase.getList({
page: pagenumber,
size: recordsize
}).then(function (data) {
console.log(data.values[0]);
console.log(data.paging.totalRecords);
});
};

Cloud code on parse.com skipping a save

I'm trying to set up a game that allows playing with random players. The code below is supposed to create a GameMessage object for both paired players. To relate both objects as part of the same game, I've decided to save the objectId of of the game made for "firstplayer" in the field "otherside" for "secondplayer" and vice-versa. For some reason (perhaps the first save of firstplayer and secondplayer isn't done before the code attempts to retrieve the objectIds, meaning there are no objectIds to get?).
Short version: Why are the "otherside" values not saving?
Parse.Cloud.define("findpartner", function(request, response) {
var User = Parse.Object.extend("_User");
var user = new User();
var currentuser = Parse.User.current();
currentuser.set("searching", 0);
var query = new Parse.Query(User);
query.equalTo("searching", 1);
query.limit(50); //limit to at most 50 users
query.find({
success: function(objects) {
var amount = objects.length;
var indexNum = Math.floor((Math.random() * amount));
var newpartner = objects[indexNum];
if (amount > 0 && newpartner.id !=currentuser.id) {
newpartner.set("searching", 0);
var Firstplayer = Parse.Object.extend("GameMessages");
var firstplayer = new Firstplayer();
var Secondplayer = Parse.Object.extend("GameMessages");
var secondplayer = new Secondplayer();
firstplayer.set("sender", currentuser.id);
firstplayer.set("receiver", newpartner.id);
firstplayer.set("sent",0);
firstplayer.set("received",0);
firstplayer.set("receiverName", newpartner.getUsername());
secondplayer.set("sender", newpartner.id);
secondplayer.set("receiver", currentuser.id);
secondplayer.set("sent",0);
secondplayer.set("received",0);
secondplayer.set("receiverName", currentuser.getUsername());
firstplayer.save().then(function(secondplayer){ <<<
return secondplayer.save(); <<<
}).then(function(firstplayer_update) { <<<
return firstplayer.save({ otherside: secondplayer.id}); <<<
}).then(function(secondplayer_update){ <<<
return secondplayer.save({ otherside: firstplayer.id}); <<<
});
newpartner.save(null, {useMasterKey: true});
}
else {
currentuser.set("searching", 1);
}
currentuser.save();
response.success(amount);
},
error: function(error) {
alert("Error: " + error.code = " " + error.message);
}
});
});
I added arrows to show where the "otherside" is. They're not in the actual code. I do not doubt the code has mistakes though, I do not know javascript. I wrote it solely by studying the parse.com documentation.

I'm not convinced that it makes sense to create these 2 independent messages and link them together, but I won't let that stand in the way of getting this working. This isn't tested, but I've refactored your code and think you should try to glean a few things from it.
// Set this up once, outside of your function, and use it everywhere
var GameMessage = Parse.Object.extend("GameMessages");
Parse.Cloud.define("findpartner", function(request, response) {
// Code defensively, make sure this function requires a user be logged in.
if (!request.user) {
console.log("non-user called findpartner");
return response.error("Unauthorized.");
}
// Get the user who called the function
var user = request.user;
// The end response is a number, apparently
var result = 0;
// The target player
var targetPlayer;
// The two messages that will be used if a match is found
var firstmsg = new GameMessage();
var secondmsg = new GameMessage();
// Create a Users query
var query = new Parse.Query(Parse.User);
query.equalTo("searching", 1);
query.notEqualTo("objectId", user.id);
query.limit(50);
// Remove public access to Find operations for Users in the Data Browser
// Use the master key to query, and use promise syntax.
query.find({ useMasterKey: true }).then(function(objects) {
result = objects.length;
// If no users were found searching, mark the user as searching and save
if (result == 0) {
user.set('searching', 1);
// Return the save promise
return user.save(null, { useMasterKey: true });
}
// Pick a random user out of the response
var indexNum = Math.floor((Math.random() * objects.length));
var targetPlayer = objects[indexNum];
// Set that user to no longer be searching and save
targetPlayer.set("searching", 0);
return targetPlayer.save(null, { useMasterKey: true }).then(function() {
firstmsg.set("sender", user.id);
firstmsg.set("receiver", targetPlayer.id);
firstmsg.set("sent", 0);
firstmsg.set("received", 0);
firstmsg.set("receiverName", targetPlayer.getUsername());
secondmsg.set("sender", targetPlayer.id);
secondmsg.set("receiver", user.id);
secondmsg.set("sent", 0);
secondmsg.set("received", 0);
secondmsg.set("receiverName", user.getUsername());
// Return the promise result of saving both messages
return Parse.Object.saveAll([firstmsg, secondmsg], { useMasterKey: true });
}).then(function(messages) {
// Set the pointers to reference each other
firstmsg.set("otherside", secondmsg.id);
secondmsg.set("otherside", firstmsg.id);
// Return the promise result of saving both messages, again
return Parse.Object.saveAll([firstmsg, secondmsg], { useMasterKey: true });
});
}).then(function() {
// All the stuff above has finished one way or the other, now we just need to
// send back the result. 0 if no match was made.
response.success(result);
}, function(error) {
response.error(error);
});
});

firstplayer.save();
secondplayer.save();
secondplayer.set("otherside",firstplayer.id); <<<
firstplayer.set("otherside",secondplayer.id); <<<
firstplayer.save();
secondplayer.save();
This is the part of code that you say not working. In parse doc you can see that .save() is a non blocking operation. Means the line firstplayer.save() goes immediately to next line(it wont block the thread for saving). So when you set id secondplayer.set("otherside",firstplayer.id) firstplayer.id is still undefined.
So if you want a synchronous logic, like save first_object then save second_object ,
you have to use call backs.
first_object.save({
success: function(saved_first_object) {
second_object.save({
success: function(saved_second_object) {
//process complete
},
failure: function(error){
}
})
},
failure: function(error) {
console.log(error);
}
})
You can also approach it using promises.

UPDATE: Based on question edit from OP trying promises
Try this
firstplayer.save()
.then(function(saved_firstPlayer){
firstplayer = saved_firstPlayer;
return secondplayer.save();
}).then(function(saved_secondplayer) {
secondplayer = saved_secondplayer;
return firstplayer.save({ otherside: secondplayer.id});
}).then(function(updated_firstplayer){
firstplayer = updated_firstplayer;
return secondplayer.save({ otherside: firstplayer.id});
}).then(function(updated_secondlayer){
secondplayer= update_secondplayer;
});

How to save my model using Parse cloud js?

I had a read of the meme example but it doesn't seem to update, just create new objects! What I want is to
a. find some given db table
b. update some fields in the db table
c. save the db table back to the database
Given this code, what is the missing piece so that I can actually update an object?
query.find(
function(results){
if (results.length > 0){
return results[0];
} else {
//no object found, so i want to make an object... do i do that here?
return null;
}
},
function(error){
response.error("ServerDown");
console.error("ServerDown - getModuleIfAny URGENT. Failed to retrieve from the ModuleResults table" + +error.code+ " " +error.message);
}
).then(
function(obj){
var module;
if (obj != null){
console.log("old");
module = obj;
module.moduleId = 10; //let's just say this is where i update the field
//is this how i'd update some column in the database?
} else {
console.log("new");
var theModuleClass = Parse.Object.extend("ModuleResults");
module= new theModuleClass();
}
module.save().then(
function(){
response.success("YAY");
},
function(error) {
response.error('Failed saving: '+error.code);
}
);
},
function(error){
console.log("sod");
}
);
I thought the above code would work - but it does not. When it finds an object, it instead refuses to save, stupidly telling me that my object has no "save" method.

First I would double check the version of the javascript sdk you're using in your cloud code. Make sure it's up to date e.g. 1.2.8. The version is set in the config/global.json file under your cloud code directory.
Assuming you're up to date I would try modifying your code by chaining the promises using multiple then's like so:
query.find().then(function(results){
if (results.length > 0){
return results[0];
} else {
//no object found, so i want to make an object... do i do that here?
return null;
}
},
function(error){
response.error("ServerDown");
console.error("ServerDown - getModuleIfAny URGENT. Failed to retrieve from the ModuleResults table" + +error.code+ " " +error.message);
}).then(function(obj){
var module;
if (obj != null){
console.log("old");
module = obj;
module.moduleId = 10; //let's just say this is where i update the field
//is this how i'd update some column in the database?
} else {
console.log("new");
var theModuleClass = Parse.Object.extend("ModuleResults");
module= new theModuleClass();
}
module.save();
}).then(function(result) {
// the object was saved.
},
function(error) {
// there was some error.
});
I think this should work. Fingers crossed. Cheers!
