Same problem here, but using PostgreSQL.
This is the function that I was using to connect to a database:
def connect_db(db_host, db_name, db_user, db_user_password):
# gets the table_hash from one of the .table files in the databases
folder
table_hash = None
for file in os.listdir(databases_folder):
if archivo.endswith('.table'):
table_hash = file.split('_')[0]
break
return DAL('postgres://%s:%s@%s:5432/%s' % (db_user, db_user_password,
db_host, db_name),
migrate=False,
folder=databases_folder,
auto_import=True,
table_hash=table_hash)
But after upgrading to 2.15.3, the function throws this error:
Traceback (most recent call last):

Meanwhile, I'll check if there is an opened issue about this.
Let me know if there is anything I can do to help you fix the problem.
