I'm using EF4 with POCO objects the 2 tables are as follows
Service
ServiceID,
Name,
StatusID
Status
StatusID,
Name
The POCO objects look like this
Service
ServiceID,
Status,
Name
Status
StatusID,
Name
With Status on the Service object being a Navigation Property and of type Status.
In my Service Repository I have a save method that takes a service objects attaches it to the context and calls save. This works fine for the service, but if the status for that service has been changed it does not get updated. My Save method looks like this
public static void SaveService(Service service)
{
using (var ctx = Context.CreateContext())
{
ctx.AttachModify("Services", service);
ctx.AttachTo("Statuses",service.Status);
ctx.SaveChanges();
}
}
The AttachModify method attaches an object to the context and sets it to modified it looks like this
public void AttachModify(string entitySetName, object entity)
{
if (entity != null)
{
AttachTo(entitySetName, entity);
SetModified(entity);
}
}
public void SetModified(object entity)
{
ObjectStateManager.ChangeObjectState(entity, EntityState.Modified);
}
If I look at a SQL profile its not even including the navigation property in the update for the service table, it never touches the StatusID. Its driving me crazy. Any idea what I need to do to force the Navigation Property to update?
