scaffold (model_id, options = {})
public
Adds a swath of generic CRUD actions to the controller. The
model_id is automatically converted into a class name unless one
is specifically provide through options[:class_name] . So scaffold
:postPost as the class and
@post/@posts for the instance variables.
It’s possible to use more than one scaffold
in a single controller by specifying options[:suffix] = true . This
will make scaffold
:post, :suffix => true
