Displaying fields rendered in a custom way

Sometimes it is useful to display extended information about an entity item, such as composite product code (f.ex., SKU), or booking total together with currency sign.

To create such a field in e.g. ListView, follow the steps below:

• define the field value calculation logic in a class implementing org.lightadmin.core.config.domain.renderer.FieldValueRenderer interface;
• pass the class instance to renderable() method of FieldSetConfigurationUnit section in the administration class;

@Administration( Booking.class )
public class BookingAdministration {

	public static FieldSetConfigurationUnit listView( final FieldSetConfigurationUnitBuilder fragmentBuilder ) {
		return fragmentBuilder
				.field( "user" ).caption( "Customer" )
				.field( "hotel" ).caption( "Hotel" )
				.field( "smoking" ).caption( "Smoking" )
				.field( "beds" ).caption( "Beds" )
				.renderable( totalValueRenderer() ).caption( "Total" )
				.build();
	}

	public static FieldSetConfigurationUnit quickView( final FieldSetConfigurationUnitBuilder fragmentBuilder ) {
		return fragmentBuilder
				.field( "checkinDate" ).caption( "Check-In Date" )
				.field( "checkoutDate" ).caption( "Check-Out Date" )
				.renderable( hotelCodeRenderer() ).caption( "Hotel Code" ).build();
	}

	public static FieldValueRenderer<Booking> totalValueRenderer() {
		return new FieldValueRenderer<Booking>() {
			@Override
			public String apply( final Booking booking ) {
				return String.format( "\u20AC %s", booking.getTotal() );
			}
		};
	}

	private static FieldValueRenderer<Booking> hotelCodeRenderer() {
		return new FieldValueRenderer<Booking>() {
			@Override
			public String apply( Booking booking ) {
				return String.format("%s-%s-%s", booking.getHotel().getId(), booking.getHotel().getZip(), booking.getHotel().getName());
			}
		};
	}
}

The above example will render the following result:
