Add service locks for earlier versions

  • To include in Ember Flexberry project LockService, adding environment.js:
// Settings lock. 
lock: {
  enabled: true,
  openReadOnly: true,
  unlockObject: true,
}

Where:

  • enabled - enable/disable LockService.
  • openReadOnly - responsible for opening edit form read-only, if the form is locked.
  • unlockObject is responsible for deleting the lock when exiting the form.
  • Add Backend ODataService library NewPlatform.Flexberry.LockService.

  • Add to ODataConfig assemblies type Lock:
    namespace NewPlatform.Flexberry.Services
    {
    ...
    var assemblies = new[] {
      ...
      typeof(NewPlatform.Flexberry.Services.Lock).Assembly
    };
    ...
    };
    
  • Retrieve current user for a lock now carried out via the method getCurrentUserName service user (defined in the addon ember-flexberry-data). By default, this method will return the user name userName. At the application level, you must override this method if you are using authentication in your app or if you want to return a different user name in case no authentication mechanism in the application.
