Writing only to public schema with Document Hierarchy

[kkorus94]

Hello. I have the following test classes:

   public abstract class NodeModel
    {
        //public string Id => Name;
        public Guid Id { get; } = Guid.NewGuid();
        public string Name { get; protected set; }        
    }

    public class NodeModel1 : NodeModel
    {
        public NodeModel1()
        {
            Name = "Node model 1";
        }        
    }

    public class NodeModel2 : NodeModel
    {
        public NodeModel2()
        {
            Name = "Node model 2";
        }
    }

    public  class TestModel
    {
        public Guid Id { get; } = Guid.NewGuid();
        public string Name => "Test model";
    }

I want to store NodeModel1 and NodeModel2 in one table using Document Hierarchies. Additionally, I intend to store the classes in different (already created) schemas, not the public one. Here is part of my repository:

public class MartenDocumentRepository<T> : IDocumentRepository<T> 
    {
        private readonly IDocumentStore documentStore;
        public MartenDocumentRepository(IDocumentStore documentStore)
        {
            this.documentStore = documentStore;
        }

        public async Task Add(T element, string schemaName)
        {            
            documentStore.Options.DatabaseSchemaName = schemaName;
            var documentSession =  documentStore.LightweightSession();

            documentSession.Store(element);
            await documentSession.SaveChangesAsync();
        }
...

When I tried to store NodeModel1 and NodeModel2 classes with no configuration, I got an error:
System.ArgumentOutOfRangeException: Specified argument was out of the range of valid values. (Parameter 'Unknown subclass type 'EasyWiseVP.Nodes.NodeModel1' for Document Hierarchy EasyWiseVP.Nodes.NodeModel')
So I added the following configuration:

builder.Services.AddMarten(options =>
{
    options.Connection(builder.Configuration.GetConnectionString("Marten"));
    **options.Schema.For<NodeModel>().AddSubClassHierarchy();**
});

Now, I don't have the error, but the classes are always stored in the public schema. When I try it for TestModel class (with no hierarchy), changing the schema works.

What can I do to alter between schemas also having the hierarchies? Thank you.

You need to specify the database schema name only at configuration time. You cannot do that at runtime, or at least that will not be honored. Try this:

builder.Services.AddMarten(options =>
{
    options.Connection(builder.Configuration.GetConnectionString("Marten"));
    **options.Schema.For<NodeModel>().DatabaseSchemaName("your schema name").AddSubClassHierarchy();**
});

@jeremydmiller Thanks for the answer. But this is my case where I think it would be beneficial: I have a master entity (Container) with lists of "sub entities" (Nodes). Now, I want to store every Container in its own schema (created dynamically - it works already). NodeModels (non-event documents) logically are bound with Containers, so I wanted to store these documents also in the dynamically created schema.
Or is it a bad idea for some reason?
