Is there such a thing as SQLAlchemy training or a SA consultant? I'm
starting to think that my team might benefit from some time with

Hello,
sqlalchemy seems to be the proper tool for my needs but I can't figure
out how to design my project or set the ORM properly.
Let's say, I build a music database, storing tracks and their
associated metadata in an sql-like database defined as such :

Thank you very much for the source,
I also learned the term of vertical paradigm and stumble upon the

Hi All,
Does anyone have any good examples of migration scripts?
The documentation is surprisingly sparse..
Of course, an alernative which doesn't do any abusive monkey patching or

SQLAlchemy seems pretty smart about updating only the changed columns in an orm
object...
If I have an orm object. Something changes one of the columns. Just before I
commit() the session, is there a way to tell which columns will be updated vs
those that are unchanged?
Any way to ascertain
