Foreign Keys in Scaffolding?

Hi everyone. There is probably a simple answer to this but I can’t seem
to figure it out.

When I scaffold a model with a foreign key, that field doesn’t show on
CRUD pages created. What gives?

I have a group and events table and I’d looking was expecting the
scaffolding to to automatically create a drop down menu on the events
pages to select a group it belongs to.

I found
that does this automaticly, but it just seems so obvious that it would
be a part of the standard scaffolding generator.

I also tried the Ajax Scaffolding extensions but it didn’t show the
foreign key fields either.

Thanks anyone for you help! As you can probably tell I’m still learning
Ruby and Rails.
