[英]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我的批处理请求有点问题,当提交并触发 odata 模型时,在批处理返回结果之前触发回调中的
that.readAndUpdateSercicePeriodPlans(oService).then(function(oSerciceO)
As you can see using my debugger, the call back function is triggered :正如您使用我的调试器所看到的,回调函数被触发:
but the network didn't return the result yet :但网络还没有返回结果:
Below is the code, what I am doing wrong?下面是代码,我做错了什么? :
:
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);
}
});
只有当过滤器中有某些值时,您的 Chrome 过滤器图标才会显示为红色。:)
After debugging all night and drinkind redbull I've finally found the issue :经过整夜调试和drinkind redbull,我终于找到了问题所在:
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.我建议避免两次添加同一组-因此我遇到了一些问题。
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);
}
}
}
