与Python Flask一起使用SQLAlchemy不起作用

Question

I've got a Flask app and I'm trying to get a SQLalchemy query using OR to return two different status like this but in one query:

        csv_list_1 = csvTable.query.filter_by(file_uuid=file_uuid).filter_by(status="Validated")

        csv_list_2 = csvTable.query.filter_by(file_uuid=file_uuid).filter_by(status="Also Validated")

I've found a couple of answers on stack overflow but trying the following:

from sqlalchemy import or_
csv_list = csvTable.query.filter_by(file_uuid=file_uuid).filter_by(or_(status="Validated", status="Also Validated"))

I get:

SyntaxError: keyword argument repeated

I'm not sure where to go from here.

Answer 1

Your column names shouldn't be keyword arguments here, it should be a boolean check like this:

csv_list = csvTable.query.filter_by(file_uuid=file_uuid)\
    .filter(or_(status == "Validated", status == "Also Validated"))
