It is common to have applications that ask for end-user authentication to use them. Besides restricting application access to authenticated end-users, it also allows implementing user-specific logic. For example, display the information on the home screen adapted to the end-user that is logged in.
To get the end-user currently logged in to the application, use the GetUserId() function.
In the GoOut mobile application, for finding, reviewing and rating places, we want to know the end-user who wrote a review. For that, we have to save the end-user identifier in the review:
- Go to the AddReview screen and open the Save action;
- Assign the value returned by GetUserId() to attribute Review.UserId ;
- Create the review using the CreateReview entity action.
