Add Association between 2 entities
The associations defined between database entities are not created automatically in the form data model. The associations between entities need to be defined using the form data model editor. Every newhire entity can have one or more beneficiaries, we need to define one-to-many association between the newhire and beneficiaries entities.
The following steps will walk you through the process of creating the one-to-many association
-
Select newhire entity and click on Add Association
-
Provide a meaningful Title and identifier to the association and other properties as shown in the screenshot below
-
Click on the edit icon under the Arguments section
-
Specify values as shown in this screen shot
-
-
We are linking the two entities using the empID column of beneficiaries and newhire entities.
-
Click on Done to save your changes
Test your Form Data Model
Our form data model now has get service which accepts empID and returns the details of the newhire and its beneficiaries. To test the get service, please follow the steps listed below.
- Select newhire entity
