Re: [web-devel] Yesod, Sqlite, Enabling Foreign Key Support

Ok. I recompiled persistent with new changes. All works how i want and expect. But now *insertBy* function are not so safe as earlier. *The insertBy function* checks only unique constrains defined on yesod framework level via Unique... constructions . Now *insertBy* function throws exception if we try to insert 'bad' value to column with foreign constraint. Please show me how to catch exception. I think it would something like: * * *import qualified Control.Exception.Control as E* *...* *do* * res <- runDB $ E.catch (insertBy offer) (\_ -> return Left ())* But my exception handler is wrong. Thanks. 2011/4/26 Greg Weber

Hi Michael.

Please show the way to enable foreign key support from sqlite connection.
