Hey people,

does anyone know if it's possible to access params inside the before_validation function?

before_validation callbacks are instance methods of models, params is
an instance method of controllers therefore you cannot call params
from a before_validation callback.

Aren't you doing something like Foo.new( params[:foo] ) already?

params is an array and responds to merge, so you can add stuff to params before passing it to the model.

Sounds like you need to add attr_accessor entries.

attr_accessor :current, :required
