OData model binding on model.read /get entity

YayatiEkbote — Thu, 27 Aug 2020 07:20:02 GMT

Hello experts,

I work as ABAP developer but I am new to SAP UI5. I have followed ui5.sap.com , walkthrough model binding concepts.

I am developing a very basic demo application for my practice.

I have an input field where I will enter company code. On button press, I am executing function onGetAddress.

In the function onGetAddress, I am giving call to the OData service.

My view is like this -

<mvc:View controllerName="CA_Descriptor.CompanyAddress_Cpy.controller.Main" xmlns:mvc="sap.ui.core.mvc" displayBlock="true" xmlns="sap.m" xmlns:f="sap.ui.layout.form">
<Page id="page" title="{i18n>title}" binding="{/CompanyAddressSet}">
  <content>
	<f:SimpleForm id="CompInput" title="{i18n>comp_sel}" editable="true" layout="ResponsiveGridLayout" labelSpanS="12" labelSpanM="3" labelSpanL="3" labelSpanXL="3" emptySpanXL="4" emptySpanL="4" emptySpanM="4" emptySpanS="0" columnsXL="1" columnsL="1" columnsM="1" singleContainerFullSize="false">
		<f:content>
			<Label id="l_bukrs" text="{i18n>l_bukrs}"/>
			<Input id="ip_bukrs" />
			<Button id="b_getAddr" text="Get Address" press="getCompAddr"/>
		</f:content>
	</f:SimpleForm>
	<f:SimpleForm id="AddrDetail" title="{i18n>comp_addr}" editable="true" layout="ResponsiveGridLayout" labelSpanS="12" labelSpanM="3" labelSpanL="3" labelSpanXL="3" emptySpanXL="4" emptySpanL="4" emptySpanM="4" emptySpanS="0" columnsXL="1" columnsL="1" columnsM="1" singleContainerFullSize="false">
		<f:content>
			<Label id="l_name" text="{i18n>l_name}"/>
			<Text id="t_Name" text="{CompAddr>/Name1}"/>
			<Label id="l_street" text="{i18n>l_stras}"/>
			<Text id="t_Street" text="{CompAddr>/Street}"/>
			<Label id="l_city" text="{i18n>l_city}"/>
			<Text id="t_City" text="{CompAddr>/City1}"/>
			<Label id="l_regio" text="{i18n>l_regio}"/>
			<Text id="t_Region" text="{CompAddr>/Region}"/>
			<Label id="l_ctry" text="{i18n>l_ctry}"/>
			<Text id="t_Country" text="{CompAddr>/Country}"/>
		</f:content>
	</f:SimpleForm>
 </content>
</Page>

My Controller is like this

sap.ui.define([
	"sap/ui/core/mvc/Controller",
	"sap/m/MessageToast"
], function (Controller,MessageToast) {
	"use strict";


	return Controller.extend("CA_Descriptor.CompanyAddress_Cpy.controller.Main", {
		onInit: function () {
			var oModel = this.getOwnerComponent().getModel("CompAddr");
			this.getView().setModel(oModel);
		},
		getCompAddr: function(){
			var gModel = this.getView().getModel();
			var vInput = this.getView().byId("ip_bukrs").getValue();
			var vQuery = "/CompanyAddressSet('" + vInput + "')";
			function fnSuccess(oData,oResponse){
				console.log("Data",oData);
				console.log("Response",oResponse);
			}
			
			function fnError(oError){
				console.log("Error", oError);
			}


			gModel.read(vQuery,{
				success: fnSuccess,
				error: fnError
				});
			
			MessageToast.show("Clicked");
		}
	});
});

When I press the button, I can see that the service is bringing the data correctly which I am logging in console. But I am unable to see the data reflected back in the view display.

I want to learn how to bind the data back to view on the button click.

I have declared model and datasource properly in manifest.json.

My manifest.json looks like this -

Re: OData model binding on model.read /get entity

Hi,

You need to make a few changes in your code.

First, you need to perform Element Binding on success function of your read call on your form layout which is showing the details.

You can find a good example for this in the SDK: Element Binding.

Additionally, I noticed that the binding in the Details form is with absolute paths (eg: {CompAddr>/Name1}). You would need to change it to Relative paths (eg: {CompAddr>Name1}).

Do let me know if you face any further issues.

Best Regards,

Rohit

Hello Rohit,

Thanks for quick reply.

In above case, which element will be appropriate for binding? According to my understanding, element will be the UI control like panel or label or text etc.. right?

Regards,

Yayati

I did the element binding to the simple form control and it started working.

Thanks for quick reply.
