Hi, I am working on a web site using Python Django and SQLAlchemy ORM. I want to do all read operations in separate database and write operations in separate database.
So I tried *Mike Bayer*'s solution ( http://techspot.zzzeek.org/2012/01/11/django-style-database-routers-in-sqlalchemy/) but query.update() and query.delete() didn't work properly. I debugged some code and modified SessionRouter class as following: class SQLAlchemySessionRouter(Session): def get_bind(self, mapper=None, clause=None): if self._flushing: return ENGINES['write-only'] elif isinstance(clause, sqlalchemy.sql.expression.Update): return ENGINES['write-only'] elif isinstance(clause, sqlalchemy.sql.expression.Delete): return ENGINES['write-only'] else: return ENGINES['read-only'] Now it is working fine in my case (I tested this manually). I need *Mike Bayer* or experts guidance. Do these modifications looks good? Should I go with this solution? Or is there some thing better that can help me?
