How to update OwnedCollection with multiple associated entities?

[cryo75]

Is it possible to update such a graph?

Hi,

I'm not exactly sure about the relations in your scenario: do you have multiple associated entities or do you have a single collection of multiple associated entities?

Anyways, it should work like this for the first case (more than one navigation property):

var attachedRoot = context.UpdateGraph(changedRoot,
    a => a.OwnedCollection(b => b.OwnedCollection,
        with => with.AssociatedEntity(d => d.FirstAssociate)
                    .AssociatedEntity(d => d.SecondAssociate)));

And like this for the second case (the navigation property is a collection):

var attachedRoot = context.UpdateGraph(changedRoot,
    a => a.OwnedCollection(b => b.OwnedCollection,
        with => with.AssociatedCollection(d => d.AssociatedCollection)));

Thanks. It is the first case.

But I don't understand the second case.

Hi,

in the second case you'd have multiple associated entities of the same type contained within a single collection. The classes would look something like this:

public class Root
{
    // [..] Id (Primary Key) etc.

    public List<OwnedEntity> OwnedCollection { get; set; }
}

public class OwnedEntity
{
    // [..] Id (Primary Key) etc.

    public List<AssociatedEntity> AssociatedCollection { get; set; }
}

public class AssociatedEntity
{
    // [..] Id (Primary Key) etc.
}
