Ruby on Rails

I now have:

model:

        attr_accessor :completed_cfdym
        def completed_cfdym
          @completed_cfdym
        end
        def completed_cfdym=(var)
          if var == 'true'
            @completed_cfdym = true
          else
            if var == 'false'
              @completed_cfdym = false
            else
              @completed_cfdym = ''
            end
          end
        end
        validates(:completed_cfdym, inclusion: { in: [true, false], message: "%{value} is not a valid response"} )

view:

      <%= f.label :completed_cfdym, "Have you already completed 'A Conversation for the Difference You Make in Life?", class: 'span5'  %>
      <%= f.select :completed_cfdym, {'' => nil, 'Yes' => true, 'No' => false}, {}, { :class => 'span1' } %>

I get the diagnostic:
* Completed cfdym is not a valid response

Is there a construct, like the %{value} that I can use to print out the response?

Removing the '' on true and false made no difference.

You're comparing with = rather than ==
