Something is very wrong with your indentation

e.g. https://github.com/Leo-g/Flask-Scaffold/blob/master/app/users/models.py#L37

def  session_commit ():
      try:
        db.session.commit()
      except SQLAlchemyError as e:
         db.session.rollback()
         reason=str(e)
         return reason
