_document_registry can't handle two mongoengine.Document classes with same name different collection

[Cediddi]

I have a medium sized application with multiple modules. Two of the modules define similar classes with different collections defined. While class names are same, because the collection names differed, I id not encountered any error. Today I tried to use GenericReferenceField and experienced an error. That was because _document_registry only keeps class names, not the class path. I can think two solutions here.

1- Register by class paths.
2- Throw errors when trying to register a different class with same name.

For backwards compatibility you might do something like this:

• Register by path, if path is already registered for another class, throw error
• Register by name, if name is already registered, just ignore and override
• Have a setting to totally disable "register by name" workflow.

These are my two cents.
