About

Fix SQLAlchemy 2.1 compatibility by checking if _ordered_values attribute exists.

  • Add hasattr() check for compile_state._ordered_values before accessing it
  • SQLAlchemy 2.1.0b1 removed the _ordered_values attribute from DMLState classes
  • Fixes failing nightly CI tests for object tracking and partial dict updates
  • Applied fix to both core20.py and core14.py compatibility modules

Hi. I was happy about this patch, but I am finding it being closed now. Wasn't it applicable/sensible, i.e. was it wrong?

@amotl

It has an experiment about asking GitHub Copilot to fix a specific issue, and unfortunately new errors were introduced. I find it safer to close it, and create a new one by hand with some of the changes from this one.
