SAP Ui5-data Model

1. JSON Model

{company    : {        "treefish Inc",        info: {            3,        },        contacts: [            {                 "Barbara",                "873"            },            {                "Gerry",                "734"            },            {                "Susan",                "275"            }        ]}    }

Access path:

/company/name/company/info/Employees/company/contacts 

2. OData Model

Sap.ui.model.odata.ODataModel is not recommended, use Sap.ui.model.odata.v2.ODataModel instead.

Declaring the OData Model

1 var New Sap.ui.model.odata.v2.ODataModel ("http://services.odata.org/Northwind/Northwind.svc/"); 2 var New Sap.ui.model.odata.v2.ODataModel ({serviceurl: "Http://services.odata.org/Northwind/Northwind.svc"}) ;

Get OData Service metadata:

var ometadata = Omodel.getservicemetadata ();

Additional information can be added when requesting OData service data:

1 varOmodel =NewSap.ui.model.odata.v2.ODataModel ({2Serviceurl: "Http://services.odata.org/Northwind/Northwind.svc",    3 serviceurlparams: {4Myparam: "Value1",5MYPARAM2: "value2"6     },7 metadataurlparams: {8Myparam: "Value1",9MYPARAM2: "value2"Ten     } One});

The service data is accessed when it is requested

"Http://myserver/MyService.svc/?myParam=value&myParam2=value2" This path,
The same is true when requesting metadata: (TODO)

Get Data:

1 omodel.getdata ("/customer (' ALFKI ')"); 2 omodel.getproperty ("/customer (' ALFKI ')/address");

varOData ={ProductId:999, ProductName:"MyProduct"}//POSTOmodel.create ("/products", OData, {success:mysuccesshandler, error:myerrorhandler});//GETOmodel.read ("/products (999)", {success:mysuccesshandler, error:myerrorhandler});//PUTvarOData ={ProductId:999, ProductName:"Myproductupdated"}omodel.update ("/products (999)", OData, {success:mysuccesshandler, error:myerrorhandler});//DELETEOmodel.Delete("/products (999)", {Success:mysuccesshandler, error:myerrorhandler});
