4D for Mobile Tutorial – Include relations

The data of your application are linked together by two types of relationship: Many to One or One to Many.

In this blog post, we will show you how to include relations. With 4D for Android and 4D for iOS, you can easily navigate between your related data. We automatically generate the transition between views in your application.

Many to One relations

This tutorial will show you how to display the category for each task in the list and detail form of your generated application.

One to Many relations

The ‘One to Many’ relation management allows you to display a list of related fields in a new view, choose the number of records in the ‘relation’ button, and display a field like title in the navigation view bar.

This tutorial will show how easy it can be to include One to Many relations in your mobile project.


Voilà! Now you know how to display related data in your mobile application. To go further you can continue with the blog or the documentation.
