[sqlalchemy] Re: Weird error using SQLAlchemy 0.7.2, MySQL, Python3, SqlSoup and relate
I'm keeping a project that does pretty much the same as SQLSoup but
also does automatic relationship and backref mapping.
It also relies on the new Declarative Base and it doesn't rely on
anything from SQLSoup, so when Soup gets discontinued, SQLasagna will
go on :)
You can see the code, fork it and help developing it on:
https://github.com/ygbr/SQLasagna
Thanks.

[sqlalchemy] Re: Weird error using SQLAlchemy 0.7.2, MySQL, Python3, SqlSoup and relate
I've got the same error on Python 2.7 under Mac OS X 10.7.1 running
with oursql 0.9.2 for Python 2.x.
But I really need Python 3 for this project as I have developed a web
framework (soon to be published on GitHub as Serendipity) that is
intrinsically linked against Python 3. This framework uses SQLAlchemy
SqlSoup as the alternative for connecting to relational databases as
it also have pluggable models for NoSQL DB's like MongoDB, CouchDB,
etc...
The ultimate goal is to provide automatic mapping on relational
databases for rapid application development.
Actually everything but relations is working fine.
I have not tested yet with manual mappings.
Are there any plans for SqlSoup continuation?

It's likely this is some simple bug in SqlSoup.I've never seen this error
in particular which leads me to believe the relate() command of SqlSoup is
probably not that widely used. I've asked on the development list if anyone
is willing to debug into simple issues like these.
The vast majority of SQLA users are on Declarative so if you'd like to
standardize on SqlSoup, that's great, but you might need to help out with
maintenance if you want your users to stay happy with it.It's a very simple
module.

all of those commas at the end of each line results in the class having a tuple
called id in it, rather than a set of attributes id, login, name etc
which declarative can interpret as mapping directives.

[sqlalchemy] Re: Weird error using SQLAlchemy 0.7.2, MySQL, Python3, SqlSoup and relate
Oh, sorry about that, I copied from a previous declaration I've been
testing using Table() objects... I did remove the ,'s and all worked
fine... The relationships are normal both in py3k and py2 with the
latest SQLA. So the problem really lies on the relate() method of
SqlSoup.
Thanks again for your time.
