catching SQLAlchemy exceptions

Question

What is the upper level exception that I can catch SQLAlechmy exceptions with ?

>>> from sqlalchemy import exc
>>> dir(exc)
[\'ArgumentError\',         


        

Answer 1

To catch any exception SQLAlchemy throws:

from sqlalchemy import exc
db.add(user)
try:
  db.commit()
except exc.SQLAlchemyError:
  pass # do something intelligent here

See help(sqlalchemy.exc) and help(sqlalchemy.orm.exc) for a list of possible exceptions that sqlalchemy can raise.
