SQLAlchemy warning: column won't be part of the declarative mapping

Question

trying to build to-do list app with python , flask and sqlalchemy; when creating a table to database i got this error

i run this command

\'from app imp         


        

Answer 1

I was having this same error. Turns out its just a litte syntax error. Column should be upcase so:

id = db.Column(db.Integer, primary_key=True)
item = db.Column(db.String(500))
date = db.Column(db.Date)

Should fix it.
