Hi,
Behold this test:
https://github.com/plq/spyne/blob/be189784b02e204b031f25bc748d9236ef7dfc59/spyne/test/test_sqlalchemy.py#L314
This is for Spyne => SQLAlchemy object bridge so please ignore
Spyne-specific stuff in there.
I noticed that this produced warning like this:
hello,
here's a test case:

that contain changes to non-sqla parts of a class?
I understand that the reason for this is D2.__mapper__.class_ != D2. Is

Hi,
I've just implemented support for scalar collections for Spyne. (In
Spyne terms that's sql serialization of an array of primitives). Seems
to be working fine so far.
The question is: Is the association proxy the only (read/write) way of
doing this? It requires the child table to be

This is the only regression I saw migrating from 0.7.9 to 0.8b2:

The fix was to remove the pformat call:

Spyne is an RPC toolkit that tightly integrates with SQLAlchemy. It's
been in development for about two years, with its first stable release
done very recently on October 29th.
