Passing Parameters between two pages in SAPUI5

[Former Member]

Hi,

In my SAPUI5 Application, i have two views, first one is Login page & second one is a Master-Detail page displaying PurchaseOrders.

The Login page & Master detail are working fine as two separate pages. But the actual requirement is to pass the Login information from Login page to Masterdetail page.

We validate the user role & access & then based on these values we take the user to the second page.

For this validation we hit ODATA service in Login page's Controller like below:

I hit the service & i get the RelCode & RelGroup from the response. I need to pass these values to my second page. I have gone through various forums & apis & found that the new functionality "subscribe" & "channel" will help pass data between pages. But i couldn't get this implementation right, with very few references available.

It would be of great help if anyone can suggest a logic to pass data between pages... Appreciate any assistance!!

LoginPagecontroller.js:

login_validate : function(oEvent)

  {

  try

  {

  //alert('1');

  var username_value = $("#username_value_id").val();

  alert('username_value '+username_value);

  var password_value = $("#password_value_id").val();

  alert('password_value '+password_value);

  var login_url = "proxy/http/incas1054.ind.cldsvc.accenture.com:8000/sap/opu/odata/sap/ZDP_MOBILE_ACCESS_SRV/LOGINACCESSSet(Uname='"+username_value+"',Password='"+password_value+"')";

  var login_Odatamodel = new sap.ui.model.odata.ODataModel(login_url,  "dev_sde", "28aug@2013");

  sap.ui.getCore().setModel(login_Odatamodel);

  var RelCode = "";

  var RelGroup = "";

  OData.request({

    requestUri : login_url,

  method : "GET",

  user: username_value,

  password: password_value,

  headers :

  {      

  "X-Requested-With" : "XMLHttpRequest",

  "Content-Type": "application/json; charset=utf-8",

  "DataServiceVersion" : "2.0",      

          "X-CSRF-Token" : "Fetch"

  }

   },

   function(data, response)

   {

   RelCode = data.RelCode;

   RelGroup = data.RelGroup;

   var oBus = sap.ui.getCore().getEventBus();

   var params = {param1: RelCode};

   //to subscribe

   oBus.subscribe("myChannel","ToDetailPage",show);

   //to publish data between pages

   oBus.publish("myChannel","ToDetailPage",params);

   },

   function(err)

   {

   alert('Error Caught '+err.message);

   }

   );

  }

  catch(err)

  {

  alert('error '+error.message);

  }

  }

  Loginpageview.js: On Logon, the page navigation is set to 2nd page. This is where i need to pass those parameters as described above.

  Logon_btn = new sap.ui.commons.Button(

  {

  id:"logon_btn",

  text: "Login",

  tooltip : "Login Here",

  press : function(evt)

  {

  if($("#username_value_id").val().length != 0 && $("#password_value_id").val().length != 0)

  {

  oController.login_validate();

  var app = sap.ui.getCore().byId("po_id");

  app.to("idPurchaseOrder1");

  //alert('end');

  }

  else

  {

  alert("Please Enter Valid Credentials.");

  }

  }

  })

----

An update to my question:

I am able to subscribe & publish the data to the second page. But i now need to know how i can set this in my ODATA URL of master/detail page:

The code below shows the RelCode i retrieved from login page's response:

createContent : function(oController) {

  var RelCode = "";

  DetailHome = function(sChannelId, sEventId, oData){

  //var RelGroup = "";

  RelCode = oData.param1;

    alert('RelCode in PO --'+RelCode);

        };

}

The above RelCode need to be passed to the Master page's service URL..

var masterServiceUrl = "proxy/http/incas1054.ind.cldsvc.accenture.com:8000/sap/opu/odata/sap/Z_PO_ORDER1_SRV/?RelGroup='RG'&RelCode='"+RelCode+"'";
