odata

问题 So here's my code sap.ui.getCore().getModel("myModel").update("/ZSystemNameSet(mandt='001')", data, null, function(datay, responsey){ sap.ui.getCore().getModel().refresh(); MessageToast.show("It worked...!! Data: "+datay+"Response: "+responsey); }, function(datax,responsex){ MessageToast.show("Sorry! Data: "+datax+"Response: "+responsex); }); Also how do I add the header attributes to the update() call? 回答1: Obviously your service uses optimistic locking and expects an If-Match header,

问题 I've tried to filter DateTime data using sap.ui.model.Filter: oTableSearchState = [new Filter([ new Filter("Date", FilterOperator.Contains, sQuery), new Filter("Another_Date", FilterOperator.Contains, sQuery), ])] it return 400 Bad String . I found that the odata request is ...$filter substringof(,Date) . So I know it's not correct that using a "string filter" to filter date. what I need is ...$filter= Date ge datetime'2016-08-17T16:00:00Z' and Date lt datetime'2016-08-18T16:00:00' Can I do

问题 I have an issue with odata. When a property that is being expanded is null it would throw an exception saying it could not find a property on the object it is expanding (obviously because it is null). I then updated Microsoft.Data.Edm to 5.6.1 as it says it has a fix for this issue. But the fix just removes any enitites from the returned data if any of the expanded properties in the entity are null. Has anyone else had this issue an have a solution for it. 回答1: You could use something like
