Root Cause

Passing a string that does not correspond to a valid column or expression to the order_by method.

generic

中文

向 order_by 方法传递了一个不对应有效列或表达式的字符串。

Workarounds

  1. 98% success Use the column attribute directly 
    session.query(User).order_by(User.name).all()
  2. 90% success Use text() for raw SQL expressions 
    from sqlalchemy import text
session.query(User).order_by(text('name DESC')).all()

Dead Ends

Common approaches that don't work:

  1. Using the string as is without validation 100% fail

    The error will persist.

  2. Renaming the column to match the string 50% fail

    This changes the database schema unnecessarily.
