well... in fact... you did defined it as an "integer" so, dont expect to get
any other class thats not Fixnum or Bignum...
but, you can also use some model validations to be sure that the user
entered an integer...
try validates_numericality_of :cost
it will stop your user from entering strings....
i`m not sure how to stop it from entering floats like "10.6", but i`m sure
there's a simple way of doing it...
you know, you're programming in ruby on rails, it IS simple.
