implementations as attribute into the instance

[loic001]

First of all, congratulations for this work!

As mentioned here "implementations are registered as attribute into the instance".

But it doesn't seem to work... It seems that the retrieve_document function is made for this but I would have preferred an instance.MyImplementedDocument approach. I don't want to use the retrieve_document function because it's just too verbose.

Can you shed some light on this?

Note that I don't want to use register as a decorator, to decouple the documents from the backend choice. For the moment I have only found this as a troubleshooting solution:

class MyMotorAsyncIOInstance(MotorAsyncIOInstance):
    def __getattr__(self, attr):
        return self.retrieve_document(attr)

But there are also embedded documents or mixins to manage so I'm not too happy with this approach. Then maybe it would be better to do that?

class MyMotorAsyncIOInstance(MotorAsyncIOInstance):
    def register(self, template):
        implementation = super(MyMotorAsyncIOInstance, self).register(template)
        setattr(self, template.__name__, implementation)
        return implementation

Thanks for your help!

Indeed, looks like the docstring is outdated. The note below doesn't mention Mixin.

I think I removed this because

• I didn't see a use case
• There could be name clashes if a Doc and an Embedded doc have the same name that could catch the user by surprise.

Do you really have a use case for this?

If you use instance.Doc somewhere, why not just import Doc?

At least, the docstring should be fixed, so thanks for reporting.
