Added a note to that affect in that section. Mental note: don’t get interrupted when working on next tutorial…

I actually tested all those methods on the declarative model…but yes, they all should work just fine.

Hmmm…looks like I dropped the create_all call from the declarative example. I just fixed that.

I messed around with the dirty call in Wing and discovered that if I add the user to the database with a session.commit() and then change one of the user’s attributes, then session.dirty picks it up. This is not clear in the official documentation. I updated this post to reflect that.

sqlalchemy.exc.OperationalError: (OperationalError) no such table: users u’INSERT INTO users (name, fullname, password) VALUES (?, ?, ?)’ ['mike', 'Mike Dirtskill', 'password']

Should the add_all() code work when appended to the declarative table definitions above?

Looks like I had it wrong in one example and right in the other. Duh! I should stick with my wxPython examples! Thanks for the heads-up.

My import’s for SA look like this, it is a bit more typing but to me it makes the code more readable and it is less likely that I step onto something (e.g. Column = ‘blabla’).

import sqlalchemy as sa
import sqlalchemy.orm as sao
import sqlalchemy.sql as sasql
import sqlalchemy.ext.declarative as sad
