Don't show form fields

Hi! I have just changed to Rails 2.0. I have red how the new scaffold is used. But while reading and doing a guide, I have this problem. After creating a scaffold of my model I implement the migration and rake it. I enter in MySQL to be sure that the table is created and everything is ok. But when I visit the scaffold URL the app seams not to detect that the table is created or that the table has no fields so everything appears blank. When I hit the "Create" button the validation warnings pop up as normal but the field inputs don't appear nowhere. I have restarted the server after the rake db:migration and I have tried to migrate to VERSION=0 and reraked but I have the same problem. Any idea?

Ok, ok. I have found lots of answers now. It seems that dynamic scaffolding is not longer supported as we used to know it. Sorry for the, I think, so repeated question since 2.0.
