我如何在 Flask-SQLAlchemy 中执行此查询？

Question

是否可能以及如何使用 SQLALchemy 在烧瓶中进行查询

SELECT * FROM records
WHERE status = 'SCHEDULE'
OR status = 'RECORDING'
OR status = 'FAILED'
AND fail_type='S3_CONNECTION'

我正在使用以下代码：

Record().query.filter(
    Record.id == record_id,
    Record.status in (Status.SCHEDULED, Status.RECORDING)
    Record.status == Status.FAILED
    Record.fail_type == 'S3_CONNETION'
).one()

但这全是 AND 而不是 or or and

我该如何查询？

谢谢

试试这个查询：

from sqlalchemy import or_
Record().query.filter(
    Record.id == record_id,
    or_(Record.status in (Status.SCHEDULED, Status.RECORDING,)
    Record.status == Status.FAILED),
    Record.fail_type == 'S3_CONNETION'
).one()
