How can I tell if a model instance is a weakref?

[cmflynn]

For example, say I have a model with a reverse relationship to another model. In order to access that related model i would have to select_related(...) or directly load the related model via await some_model.some_related_model.load(). Once that related_model is loaded its no longer a weakref. (perhaps im using the wrong term here to describe a related model pre/post load)

in any case, is there a way to determine that the related_model has not been loaded yet? im aware i could look for fields of that model that are not available pre-load and determine that way, but im looking for a more general approach to determining this.
