Hello. I've encountered a common problem that appears when switching from MySQL to PostgreSQL, related to the following error: "column X must appear in the GROUP BY clause or be used in an aggregate function"
I've found some posts that explain why it does happen and how to correct it. But I wonder why Rails does not handle it through its DB adapters. I'm using query methods like #group, #join etc. Isn't it the reason why we use ORM? Or maybe I'm doing something wrong? Thanks. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
