I know you can set this constraint if you are directly dealing with
sqlite3, but how can I achieve this database level setting from within
sqlalchemy?
The documentation reads:
"Note that these clauses are not supported on SQLite, and require
InnoDB tables when used with MySQL. They may also not be supported
on other databases."
So is there a way to turn this feature on from within sqlalchemy? Thanks.
that documentation is probably out of date. The ON DELETE CASCADE
directive will emit on SQLite like on any other backend. You would
need to enable foreign key support on a per-connection basis for sqlite3
in order for them to take effect:
