Answer 1

The other answer only works with flask_sqlalchemy, not flask and sqlalchemy.

If you want to use native SQLAlchemy, you can do this as a quick fix: http://yuji.wordpress.com/2014/01/07/use-native-sqlalchemy-in-flask-debugtoolbar/

from flask.ext.sqlalchemy import _EngineDebuggingSignalEvents
_EngineDebuggingSignalEvents(engine, app.import_name).register()
# use at your own risk! a development environment shouldn't really care though!

The explain/select endpoints don't work without wiring them into your project manually, but at the very least your query debugger (count and sql) works. I was trying to understand what kind of queries my alchemy was forming, and I got it.
