Hi,
The flavor field of the Instance object is a lazy-loaded field and the
projects field of the Flavor object is also lazy-loaded. Now it seems
to me that when the Instance object lazy loads instance.flavor then the
created Flavor object is orphaned [1] therefore
instance.flavor.projects will never work and result in an exceptuion:
OrphanedObjectError: Cannot call _load_projects on orphaned Flavor
object.
Is the Flavor left orphaned by intention or it is a bug?
The payload of instance.<action> notifications contains the flavor
related data of the instance in question and to have the
flavor.projects in the payload as well the code would need to access
the projects field via instance.flavor.projects.
Cheers,
gibi
