Many to One relations

This tutorial will show you how easy it can be to include Many to one relations in your mobile projects.

note

In this tutorial, we will use the relation names between your tables. Giving descriptive relation names can make your project structure definition easier.

Let's get started by downloading the Starter project:

Starter project

Here we want to display the category for each task in the detail form of your generated app. To do so, open the StarteriOSProject from Open > Mobile Project...

Then go right to your Structure section and select the Task table.

Structure section

• You can notice that the TaskCategory relation is underlined

• Clicking on it will display available fields through this relation

• Select the Name field

• This field will operate as any other field for the rest of the app creation process

• You can also filter your app content using related fields from the Data section. To do so enter TaskCategory.Name != 'Personal' in the Filter query field to exclude personal tasks.

  

• You can then select an icon as well as formatters and define short and long labels from the Labels and Icons section

• Go to the Forms section and drag the field on the Task Detail form

• Build and Run

You should see your related field in your app detail form !
