Hi all,
I have discovered that with nhibernate profiler with entities created
for the very first time...
In my application I create a new entity that has a list of steps, and
each step a list of values. (I'm using inverses on mappings). Also
entities and steps references to master values already in db. So there
is a kind of mix of old and new objects.
When I do the first Save I do Session.Save(entity) and the whole tree
is saved in database as it should be, but NH profiler warns about
that:
Unable to determine if StepValueEntity with assigned identifier
ede6a5ee-b4bd-4f67-9c64-11ef85b7d6ff is transient or detached;
querying the database. Use explicit Save() or Update() in session to
prevent this.
And effectively prior all the new entities insert there are a lot of
useless selects from NH because entities are not on DB.
This is very inefficient, so what is the correct way to store those
new entities and tell NH that they are new?
FYI this is how I do mapping for identity columns, maybe this doesn't
give a clue to nhibernate to know about what are new and already
persisted entities and I should do it in another way.
Id(x =>
x.Id).Column("GUID_PIPELINE_STEP_PARAMETER").GeneratedBy.Assigned();
Thanks in advance
