Usage Considerations for Working with Records

Working with records using base components make Lightning Data Service available to you without additional configuration, but there are a few custom use cases to consider.

Consider the following use cases.

• To display a record form based on a record type, which includes picklist values based on the record type, get the record type Id.
• To notify a parent component about a successful record submission, dispatch and handle a custom event.

Picklist fields display values according to your record types. When working with lightning-record-form or lightning-record-edit-form, you must provide a record type Id if you have multiple record types on an object and you don’t have a default record type. Otherwise, the default record type Id is used.

To retrieve record type information, use the getObjectInfo wire adapter.

Display a record create form based on a record type by providing the record-type-id attribute. This example shows a form that you can place on an account record page. The form displays fields, which include a picklist with values based on the given record type Id.

Import the getObjectInfo module and a reference to the account object. The recordTypeId getter returns the Id that matches the record type name Special Account.

The recordTypeInfos property returns a map of record type Ids that are available in your org.

The lightning-record-form, lightning-record-edit-form, and lightning-record-view-form components come with event handling via onsubmit, onsuccess, and onerror attributes. To pass your form data to the container component, create a custom event.

Let’s say you have a container component c-wrapper, and your form is in the component c-account-creator. Let’s pass the Id of the new record to the container component. In c-wrapper, create an instance of c-account-creator.

When the record is created successfully, the newrecord event is dispatched by the onsuccess handler on lightning-record-form, which then calls the handleNewRecord method with the record Id.

In c-account-creator, the createStatus property displays a message with the Id of the newly created record.

The handleAccountCreated method handles the success event.
