Steps 332 - 364 Introduction Singleton Pattern SysSuperClass External Login Access Groups Access Group Editor

Chapter 11: User Login, Access Groups, Default SuperClass, Singleton Pattern, and Merge Model

332. Go to the Wiki, click on Model Examples in the top menu, and download the SysUserAuthentication model.

333. Open and Merge in the downloaded file.

334. Verify that SysSingleton has the property IsSingleton set in the objects inspector.

335. Make sure you understand the Singleton pattern.

336. Start the prototyper with XML persistence.

337. Test the OCLSingleton operator in the prototype with this expression:SysSingleton.oclSingleton - ensure you get an object.

338. Select the SysSingleton CurrentUser association in the class diagram. Check that Persistent is set to false, and thus, the association is transient.

339. Select the SysSuperClass in the diagram. Check OnCreate  and OnUpdate on the Wiki.

340. Make sure you understand what OnCreate and OnUpdate do. Follow the video on how the debugger is used to verify the theory on how it works.

341. Ensure that SysSuperClass is the default superclass for the AuthenticationPackage.

342. Check the oclIsTypeOf, oclIsKindOf, and superTypes operators in the debugger.

1. Write SysSingleton.oclSingleton.oclIsTypeOf(SysSuperClass)

  • Execute (F5).
  • Verify you get ✅, signifying it is true

2. Write SysSingleton.oclSingleton.oclIsKindOf(SysSuperClass)SysSingleton

  • Execute (F5)
  • Verify you get ✅, showing it’s a subclass of SysSuperClass

3. Write SysSingleton.superTypes

  • Verify you get “SysSuperClass”

343. Set the Default superclass of Package1 to SysSuperClass.

344. Start the debugger or refresh the model. Make sure Person now has the ChangeTime attribute.

345. In the debugger, set the empty Guid property to a new Guid for all persons.

  • Click on "Action" to change Person.allinstances from an OCL to an Action expression
  • Set this expression: Person.allinstances->collect(p|p.Guid:=Guid.NewGuid)
  • Execute(F5). You should see a new Guid assigned to the Guid.
  • Save

346. When you save all persons, ensure the ChangeTime is updated.

347. Start the Local Turnkey Prototyper.

348. Try to login with any user.

349. Register a new user with email and password.

350. Go to the debugger and check that you have a new SysUser object.

  • Input SysUser.allinstances and verify that a new SysUser has been created.

351. Go to the ViewModel Editor, select the CarSeeker ViewModel and click on the box to set its AccessGroups to IsLoggedIn. Save.

352. Try accessing CarSeeker. Ensure you cannot see CarSeeker when you are not logged in.

353. Ensure you can see CarSeeker only when you are logged in.

354. Go to the AccessGroup-tool button found at the top menu, next to the Actions Editor button.

355. Check the expressions that build up the IsLoggedIn access group and see that you understand them.

356. Add a new access group: IsAdministrator

  • Set both the Enable Expression and Viable Expression to: SysSingleton.oclSingleton.CurrentUser.IsAdmin=true
  • Save  

357. Refresh the AutoForms. Make sure you get Autoforms for SysUser.

358. Go to AutoformSysUser and set the access group to IsAdministrator.

359. Check the result on your webapplication.

360. Ensure you don't get access and get an error message ("Access denied").

361. Create a new ViewModel name AccessDenied to explain that the user does not have access.  Double-click to add the row and input “ in the Expression box. Save.

362. Set the access group for AutoFormSysUserSeeker to IsAdministrator.

  • Go to the debugger and Re-Read the model.
  • Write the expression: SysUser.allinstances. Save
  • Open the Seeker and tick the IsAdmin box. Save

363. Ensure you can get into AutoFormSysUserSeeker since you are now an administrator.

364. Create a new user b@b.se (or something else) and log in as that. Confirm that this user does not reach the AutoFormSysUserSeeker but, ends up at the AccessDenied view.
