Nevin O'Regan 3 Component That Displays Information Related To A Lookup Field
I have a lookup field in the Contact record which looks up to a custom object Application__c. How can I show fields in a component related to the Application record? Is there a standard way of doing this?
I was able to achieve this by creating an Action of type 'Update Record' on the Application and then add the 'Related Record' standard component to the Contact page.

In the lightning component you need to get the ID of the contact record > pass it to the client side controller > invoke apex code to get the application__c object details > pass back to the client side controller > display in the component as per your need.
Another approach is using Lightning Data Service which gives advantage of not implementing query functionality. passing recordId will get you the field values on the UI.
