Hello,
Having a slight issue and would like some solutions/suggestions, I
have for example 2 tables. TableA and TableB (mind my names), The
tables Look like so:
TableA
----------
Id
Name
RowVersion
TableB
----------
Id
TableAId
Name
RowVersion
I have a service method which inserts a new TableB, this talks to my
repository to do an insert.
public void Insert(TableB entity) {
entity.Validate();
repository.Insert(entity);
}
No here is my issue, on my view I am passing in a new TableB like
this, the below is a view method which builds up the entity and passes
off to the service:
// Build entity
TableB entity = new TableB();
entity.Id = view.Id;
entity.TableA = new TableA() {
Id = view.TableAId;
};
entity.Name = view.Name;
entity.RowVersion = view.RowVersion;
// Pass to service
service.Insert(entity);
With mapping the TableA relationship I am just setting the Id hoping
NH will sort it out, but due to the rowversion is null it thinks it is
transient so it is creating a new TableB entity. One solution I came
up with was in my presenter use the TableA service to resolve by Id
and attach, this works fine, but puts this login in my presenter
(yuck).
So my current solution is to change my service method to check if the
TableA's Id is set then use the repository for TableA to resolve by Id
and then attach it like this. Seems to work ok for now.
Has anyone got any suggestions for me on this topic on how I can make
this easier?
Cheers
Stefan
