SQLAlchemy Typing, Docker Python and ODBC

This release is available on Docker and pip. Key enhancements are noted below.

SQLAlchemy Typing - Attributes, Relationships

models.py creation has been enhanced to take advantage of SQLAlchemy 2 typing improvements:

• Decimal attributes are typed, complementing SQLAlchemy typing for int, string and date.

• Relationship typing has been reworked.

These provide improved code completion in your IDE.

In addition, projects now include a simple Python program to explore SQLAlchemy connectivity. To see it for the sample app, click here.

Breaking change: in the past, the parent accessor was named parent. It is now the name of the parent class. See Department in the sample database.

• Python version: now 3.11.4

Optimistic Locking, Dependencies Upgrade
