How to perform an update to an entity object from client side code?

[GCS]

I have client side code that is executed via the common tasks.

After the code is finished I would like to update a record in the database.

In the client side script, I already have the ID of the record to be updated.

Is there a possibility either to call a business rule or something or to do any kind of server request to update the record?

Would sData be the right thing to perform this task?

I found a way to do this via the client side sData service:

// getting the service

var service = new Sage.SData.Client.SDataService(

  {
    serverName: window.location.host,
    virtualDirectory: 'sdata',
    applicationName: 'slx',
    contractName: 'dynamic',
    userName: 'admin',
    password: 'mypassword',
    json: true

  }

);

// getting the (in this case it's attachment) record to be updated by the attachment ID I selected before (strID)

var request = new Sage.SData.Client.SDataSingleResourceRequest(service)
  .setResourceKind('attachments')
  .setResourceSelector("'"+strID+"'");
  request.read(

  {
    success: function (entry)

    {

      // writing the new custom Id into a custom field in attachment
      entry.CustomID = strNewCustomId;

      // updating the selected record
      request.update(entry);
    }
 });

Is there a way to retrieve the credentials from anywhere instead of hardcoding them into the JavaScript?

Hi,

you can use callback...

Hope this help.

I have solved this problem by using the credentials from the connection string and sending them to the JavaScript function as parameters.
