Hello, I'm sorry but I'm not able to use web2py with this type of db.
I just installed mysql version 8.0.15 on windows 10 pro and I have
connector for Python 3.7 and 2.7 installed
I created using mysql.exe a db named 'gadb', without any tables.
with web2py I created a new "welcome" application changing db.py in this
way (not using appconfig.ini)
i changed only this:
db = DAL('mysql://root:rootpassword@localhost/gadb',pool_size=20)
commenting this
"""db = DAL(configuration.get('db.uri'),
pool_size=configuration.get('db.pool_size'),
migrate_enabled=configuration.get('db.migrate'),
check_reserved=['all'])"""
but when I try to start the application I have this error:

What is my mistake? Thank in advance for who will answer me. Maybe this mysql
is not compatible with web2py 2.16? How can I test if web2py is able to connect
to mysql? After this problem I have to migrate a sqlite application to mysql:
this is my goal. Thank you
