problem with combined use of SchemaDocument-based classes and use_autorefs flag

[Hervé Ménager]

Hi,

I am currently trying to create a document with a pretty complex nested structure (named DocC for instance):

- Some parts of the nested structure are exclusive to the document so I modelized them as SchemaDocument classes (DocB), 

- other items are referenced by multiple documents, so I referenced them as separately stored documents (DocA). 

The issue I have is that when I try to save the resulting structure using autorefs I get an error. The test.py illustrating example attached results in an AttributeError such as this one:

Traceback (most recent call last):

  File "test.py", line 33, in <module>

    dc.save()

  File "/local/lib/python2.7/site-packages/mongokit/document.py", line 410, in save

    self.validate(auto_migrate=False)

  File "/local/lib/python2.7/site-packages/mongokit/document.py", line 228, in validate

    self._make_reference(self, self.structure)

  File "/local/lib/python2.7/site-packages/mongokit/document.py", line 679, in _make_reference

    doc[key].save()

  File "/local/lib/python2.7/site-packages/mongokit/schema_document.py", line 379, in __getattr__

    return dict.__getattribute__(self, key)

AttributeError: 'DocB' object has no attribute 'save'

which leads me to think that when using autorefs mongokit also tries to save the SchemaDocument structures separately?

Commenting use_autorefs will solve the exception problem but then DocB is embedded in DocC.

Did I miss something? Is this a bug, a limitation, or a lack of understanding from me?

Regards,
