Question

in the previous rails versions you ran

what is the new way and how do you generate scaffolds and controllers/migratations ext..

Answer 1

You want:

rails new whatevertheappsname -d mysql

Generation of scaffolds/etc. is like this:

rails generate scaffold blah name:string content:text ...
rails generate migration add_field_to_blah ...
