ValueObject not stored / useable

[puschie286]

ValueObjects seems to be not stored by default and [Owned] doesnt work when using ValueObjects with abp. ( Microsoft Source )

You can force ef to store them but it will ignore futher configuration ( like IsRequired ) and it requires you to always define the column name for ValueObjects with multiple properties

// dbcontext configuration
builder.Entity<Request>( e =>
{
	// valueobject with one property
	e.OwnsOne( x => x.Time );
	
	// valueobject with multiple properties
	e.OwnsOne( x => x.Time, n =>
    {
	n.Property( x => x.Start ).HasColumnName( "Request_Start" );
        n.Property( x => x.End ).HasColumnName( "Request_End" );
    } );
}
// entity
public class Timerange: ValueObject
{
	public DateTime Start { get; }
	public DateTime End { get; }

	private Timerange() {}

	public Timerange( DateTime start, DateTime end )
	{
		Start = start;
		End = end;
	}

	protected override IEnumerable<object> GetAtomicValues()
	{
		yield return Start;
		yield return End;
	}
}

checked all examples but you dont use ValueObjects at all so im a bit curios if it works at all ?
Would be great to see an example about how to use ValueObjects and specific as primary ( to prevent using plain GUID and assign a GUID from a different entity )

ABP Framework version: 4.4
Database provider: EF Core

Found a workaround for now ( Source

Define navigation after OwnsOne for additional configuration

// single propterty valueobject
e.OwnsOne( x => x.Optionen );
e.Navigation( x => x.Optionen ).IsRequired();
// multiple property valueobject
e.OwnsOne( x => x.Zeit, b =>
{
    b.Property( x => x.Start ).HasColumnName( "Zeit_Start" );
    b.Property( x => x.End ).HasColumnName( "Zeit_End" );
});
e.Navigation( x => x.Zeit ).IsRequired(); // not possible to configure specific for each property

still prefer to use annotation for this configuration to DRY for every entity that use value objects ( so almost all )
