I am having torubles with my model.
I have the code:

 class Typeofaid < ActiveRecord::Base
  validates_inclusion_of :type, :in => %w(Food Water Health)
end

But whenever I type ‘Food’ etc in the box I get

`1 error prohibited this typeofaid from being saved:

    * Type is not included in the list
`

Can anyone help?

    I think you have to facturize your model using the type attribute instead of just entering some value using an input box.

    “type” is a reserved column for single table inheritence in Rails.
