带有多个参数的SQLAlchemy“或”语句

Question

I have a query that require to use the "or" | 我有一个需要使用“或” | operator : 运营商：

Mymodel.query.filter((Mymodel.a== 'b') | (Mymodel.b == 'c'))

That works fine. 这很好。 However, I want my conditions to be put in an array of unkown length : 但是，我希望我的条件放在一个未知长度的数组中：

conds = [ Mymodel.a== 'b', Mymodel.b == 'c', Mymodel.c == 'd']
Mymodel.query.filter(???(conds))

Thanks ! 谢谢！

Answer 1

You are looking for or_ 你在找or_

conds = [ Mymodel.a== 'b', Mymodel.b == 'c', Mymodel.c == 'd']

If you have the above list of conditions just pass them all to or_ 如果您有上述条件列表，只需将它们全部传递给or_

from sqlalchemy import or_
Mymodel.query.filter(or_(*conds))
