Sometimes, ActiveRecord is not enough… or maybe, it would be, but I don’t know how!
So I discovered some usefull stuff: ActiveRecord::Base.connection
We can ask directly to our db trough an sql request like this
ActiveRecord::Base.connection.select_all <SQL STRING>
It does return an array of Hash.
Take care of what kind of request you want to do. If it is an update, or insert or delete, the connection method you’ll need will be execute
ActiveRecord::Base.connection.execute <SQL STRING>
