python flask 框架多表连接查询

Question

sql语句是这样的，不熟悉SQLAlchemy 不知道该怎么写，求大神帮助
SELECT A.project_id,A.creator,A.ip,B.auto_id,B.argument,B.status,B.reportlink,B.taskid
FROM (
SELECT project_id,creator,ip
FROM application
WHERE project_id IN (25696)
)
A
LEFT OUTER JOIN
auto_test
B ON A.project_id = B.project_id;

Answer 1

sql_data =  db.session().query(application,auto_test )
sql_data = sql_data.join(auto_test, application.project_id == auto_test.project_id)
sql_data = sql_data.filter(
    func.find_in_set("25696", application.project_id) 
).all

你试试看呢，方法如此，auto_test, application是定义的model名称
