Hey guys,
I just started learning how to use RORs and am really satisfied with
it. I installed it and created my first web page in under two hours.
I’ve decided to make a more advanced page by using an existing SQL
server database but there does not seem to be anything documentation
online on how to use existing databases. Do I just edit my
database.yml file? Do I still have to migrate everything? Will ROR
understand my current database structure?
ROR will not understand the current structure. It’s good, but it’s not
that good. 
See:

And:

HTH,

Thanks I will give it a shot.
