Using lightning-record-form Component
Using this component to create record forms is easier than building forms manually with lightning-record-edit-form or lightning-record-view-form. The lightning-record-form component provides these helpful features:
- Switches between view and edit modes automatically when the user begins editing a field in a view form
- Provides Cancel and Save buttons automatically in edit forms
- Uses the object’s default record layout with support for multiple columns
- Loads all fields in the object’s compact or full layout, or only the fields you specify
lightning-record-form implements Lightning Data Service and doesn’t require additional Apex controllers to create or edit record data. It also takes care of field-level security and sharing for you, so users see only the data that they have access to.
Load A Record Using lightning-record-form:
The simplest way to display a record is to use the lightning-record-form. Let’s understand this with the below example:
Create a component(LWC) with the name as lwcLightningRecordForm and add the following code:
<template>
<lightning-card title="Lightnig Record Form">
<lightning-record-form
record-id={recordId}
object-api-name={objectApiName}
fields={fields}
mode="readonly">
</lightning-record-form>
</lightning-card>
</template> Here mode Specifies the interaction and display style for the form. Possible values: view, edit, readonly. If a record ID is not provided, the default mode is edit, which displays a form to create new records.
If a record ID is provided, the default mode is view, which displays field values with edit icons on updateable fields.
import { LightningElement, api } from 'lwc';
import NAME_FIELD from '@salesforce/schema/Account.Name';
import PHONE_FIELD from '@salesforce/schema/Account.Phone';
import ANNUALREVENUE_FIELD from '@salesforce/schema/Account.AnnualRevenue';
import ACCOUNT_OBJECT from '@salesforce/schema/Account';
export default class LwcRecordViewForm extends LightningElement {
@api recordId;
objectApiName = ACCOUNT_OBJECT;
fields = [NAME_FIELD, PHONE_FIELD, ANNUALREVENUE_FIELD];
}On Line 2-5 we are importing the references of fields and object.
At Line 8 we have created a public property recordId which will inherit the record Id if placed on the account’s record page.
<?xml version="1.0" encoding="UTF-8"?>
<LightningComponentBundle xmlns="http://soap.sforce.com/2006/04/metadata" fqn="helloWorld">
<apiVersion>52.0</apiVersion>
<isExposed>true</isExposed>
<targets>
<target>lightning__AppPage</target>
<target>lightning__RecordPage</target>
<target>lightning__HomePage</target>
</targets>
</LightningComponentBundle>Please add this component to the account record page. You will get an output like the below:
Edit A Record Using lightning-record-form:
Let’s update the lwcRecordForm component created above to edit a record.
Here we have added the mode=”edit” along with onsubmit and onsuccess handler.
<template>
<lightning-card title="Quick Edit">
<lightning-record-form
record-id={recordId}
object-api-name={objectApiName}
fields={fields}
mode="edit"
onsubmit={handleSubmit}
onsuccess={handleSuccess}>
</lightning-record-form>
</lightning-card>
</template>import { LightningElement, api } from 'lwc';
import { ShowToastEvent } from 'lightning/platformShowToastEvent';
import NAME_FIELD from '@salesforce/schema/Account.Name';
import PHONE_FIELD from '@salesforce/schema/Account.Phone';
import ANNUALREVENUE_FIELD from '@salesforce/schema/Account.AnnualRevenue';
import ACCOUNT_OBJECT from '@salesforce/schema/Account';
export default class LwcRecordForm extends LightningElement {
@api recordId;
objectApiName = ACCOUNT_OBJECT;
fields = [NAME_FIELD, PHONE_FIELD, ANNUALREVENUE_FIELD];
handleSubmit(event) {
// Here we are overriding AnnualRevenue just for demo purpose.
// On the project you can do a field validation or appending/overriding any information to a field
event.preventDefault(); // stop the form from submitting
const fields = event.detail.fields;
fields.AnnualRevenue = '2000000'; // modify a field
this.template.querySelector('lightning-record-form').submit(fields);
}
handleSuccess(event) {
const evt = new ShowToastEvent({
title: 'Account Updated',
message: 'Record ID: ' + event.detail.id,
variant: 'success',
});
this.dispatchEvent(evt);
}
}
Create A Record Using lightning-record-form:
For this example we would be creating contact records from account detail page. Here we have not added the record-id as done in above cases.
<template>
<lightning-card title="Quick Contact Create">
<lightning-record-form
object-api-name={objectApiName}
fields={fields}
onsubmit={handleSubmit}
onsuccess={handleSuccess}>
</lightning-record-form>
</lightning-card>
</template>import { LightningElement, api } from 'lwc';
import { ShowToastEvent } from 'lightning/platformShowToastEvent';
import FIRST_NAME_FIELD from '@salesforce/schema/Contact.FirstName';
import LAST_NAME_FIELD from '@salesforce/schema/Contact.LastName';
import ACCOUNT_ID_FIELD from '@salesforce/schema/Contact.AccountId';
import CONTACT_OBJECT from '@salesforce/schema/Contact';
export default class LwcRecordForm extends LightningElement {
@api recordId;
objectApiName = CONTACT_OBJECT;
fields = [FIRST_NAME_FIELD, LAST_NAME_FIELD];
handleSubmit(event) {
event.preventDefault(); // stop the form from submitting
const fields = event.detail.fields;
fields.ACCOUNT_ID_FIELD = this.recordId;
this.template.querySelector('lightning-record-form').submit(fields);
}
handleSuccess(event) {
const evt = new ShowToastEvent({
title: 'Contact Created',
message: 'Record ID: ' + event.detail.id,
variant: 'success',
});
this.dispatchEvent(evt);
}
}Preview the above component in the account record page. You will get an output like below:
