Nested StorageObj

[polsm91]

First:

In [6]: o = Obj('some')                                                                                                                                                                       

In [7]: o.name='bla'                                                                                                                                                                          

In [8]: d = ObjO('someot')                                                                                                                                                                    

In [9]: d.internal = o      

Then:

# coding: utf-8
from storage.api import StorageObject
class Obj(StorageObject):
    '''
    @ClassField name str
    '''

class ObjO(StorageObject):
    '''
    @ClassField internal __main__.Obj
    '''

o = ObjO.get_by_alias('someot')
o.internal
o.internal.name

Results in:

In [6]: o.internal.name
