如何使用peewee设置或选择postgres的current_settings？

Question

I have a postgres database that I want to query with peewee in python. If I connect to the database directly (psql or pgadmin) I can do something like

set my.setting='test'

or

select current_setting('my.setting')

How can I do this with peewee? The model I have contains only the tables I have in my database.

Thanks for help!

You can execute raw SQL using the Database method execute_sql(), example:

db = PostgresqlDatabase("test")
db.execute_sql("set my.setting to 'test'")
cur = db.execute_sql("show my.setting")
print(cur.fetchone()[0])
