`ModelBase.__to_dict__` can infinitely recurse about alchy

[dgilland]

This is the expected behavior for to_dict(). The default implementation doesn't guard against recursion. By default it will try to serialize all ORM columns and relationships to the detriment of infinite recursion. Since alchy can't really know when the user wants the serialization to stop, it's on the user to override this when needed.

Feel free to close then... this just surprised me.

And thanks for Alchy... has come in very handy for separating SQLAlchemy models from Flask-SQLAlchemy.

You may also want to check out sqlservice (sort of the next generation of alchy). It's currently not as feature rich as alchy but it does a few things differently that may be useful to you.
