Create coverable entities

About this task

Create an entity for the new policy line. In this example, the policy line is a coverable object. For the Golf Cart line of business, the PolicyLine subtype is GolfCartLine.

Note: For detailed instructions on how to create new entities see Defining a new data entity.

Create the new policy line entity. For Golf Cart, create the GolfCartLine entity. These steps create the basic entity definition. Add additional columns and data objects as needed after the verifying the basic definition.

Procedure

In Studio, navigate to configuration > config > Extensions. Then right-click Entity node and select New > Entity. In the Entity dialog box, enter the following properties:

Property	Value
Entity	This parameter corresponds to the desc parameter you specified in Register the new line of business when you added a new typelist extension named InstalledPolicyLine.GO.ttx. For the Golf Cart example, enter `GolfCartLine`.
Entity Type	`subtype`
Desc	`Golf Cart line of business`
Supertype	`PolicyLine`

Studio creates GolfCartLine.eti.

In GolfCartLine.eti, set displayName to the value Golf Cart Line.

Add the following elements to the GolfCartLine subtype.

If the line is a coverable object, add a ReferenceDateInternal field as a column element. Add the field by adding a new column element with the following properties:

Property	Value
`name`	`ReferenceDateInternal`
`type`	`datetime`
`nullok`	`true`
`desc`	`Internal field for storing the reference date of this entity on bound policy periods.`

In the entity, add a delegate that implements gw.api.policy.PolicyLineMethods. For the Golf Cart line, the delegate is gw.lob.go.GOPolicyLineMethods. To add the delegate, add an implementsInterface element to the subtype with the following properties:

Property	Value
iface	`gw.api.policy.PolicyLineMethods`
impl	`gw.lob.go.GOPolicyLineMethods`

For more information, see <implementsInterface>.

Optional. Add additional columns or other elements as needed. For example, as you define the GOCart entity, add a foreignkey element that points back to the GolfCartLine entity. On the GolfCartLine entity, define a onetoone element that provides access to the GOCart entity.
If you switch to the Text tab of the Entity editor, the code in the GolfCartLine.eti file appears similar to the following:
```
<?xml version="1.0"?>
<subtype
  xmlns="http://guidewire.com/datamodel"
  entity="GolfCartLine"
  desc="Golf Cart line of business"
  supertype="PolicyLine">
  <column
    desc="Internal field stores the reference date of this entity on bound policy periods"
    name="ReferenceDateInternal"
    nullok="true"
    type="datetime"/>
  <implementsInterface
    iface="gw.api.policy.PolicyLineMethods"
    impl="gw.lob.go.GOPolicyLineMethods"/>
</subtype> 
```

Add the other entities needed for the Golf Cart line, as shown in the object model diagram.

Note: Unlike GolfCartLine, GOCart is not an entity subtype of another entity. Define GOCart as an entity rather than as a subtype.
