332. Go to the Wiki Model Examples and download the SysUserAuthentication model.
333. Open and Merge in the downloaded file.
334. Verify that the SysSingleton has the property IsSingleton set in the objects inspector.
335. Make sure you understand the Singleton pattern. Check the Wiki and also google the concept: https://en.wikipedia.org/wiki/Singleton_pattern
336. Start the prototyper with XML persistence.
337. Test the OCLSingleton operator in the prototyper - 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 the OnCreate and OnUpdate on the Wiki.
340. Make sure you understand what OnCreate and OnUpdate actually do. Make use of the debugger to verify your theory on how it works.
341. Ensure that the SysSuperClass is the default superclass for the AuthenticationPackage.
342. Check the oclIsTypeOf and oclKindOf and superTypes operators in the debugger.
343. Set the Default superclass of Package1 to the 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.
346. When you save the persons, ensure the ChangeTime is updated.
347. Start Local Turnkey Prototyper.
348. Try and 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.
351. Go to CarSeeker ViewModel and set AccessGroup to IsLoggedIn. Save.
352. Ensure you cannot see CarSeeker when you are not logged in.
353. Ensure you can see CarSeeker when you are logged in.
354. Go to the AccessGroup-tool button.
355. Check the expressions that build up the IsLoggedIn access group and make sure you understand them.
356. Add a new access group: IsAdministrator
357. Refresh the AutoForms. Make sure you get Autoforms for SysUser.
358. Go to AutoformsysUser and set access group IsAdministrator.
359. Do the same for AutoFormSysUserSeeker.
360. Ensure you don't get access.
361. Create a new ViewModel name: AccessDenied. Make it explain that the user does not have access.
362. Use the debugger and set the user as IsAdmin. 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 instead, ends up at the AccessDenied view.
