I'm not sure what your goal is. Do you mean you want to give User a 
__parent__ and a __name__ within the factory already? Could you explain 
why? It will be given a location automatically as soon as it leaves the 
factory. locate is only useful on objects that you retrieve elsewhere 
(and you want to get their URL or do a security check).

This looks odd. What's Pgrestraject? The context of a traject shouldn't 
be another traject, it should be some model (such as your application).

If it's your application, you could use getSite() or (getApplication 
once it's there).
