Ruby on Rails

The second attr is a transient only used when the user signs up for an account, so I did not want to save it it in the database.

I now have in the 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"} )

The '' is because I do want force the user to answer.

And the 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' } %>

This still fails with:
Completed cfdym is not a valid response

It also does not preserve the value that I set when it displays the error and goes back to the '' => 'nil' setting

What exactly are you trying to achieve with this approach, why do you need to have the second attr not in the database and validated?

To answer your question, yes you can force it to be a boolean, by creating your own accessor methods

Instead of attr_accessor :attrvalue
  def attrvalue
    @value
  end

  def attrvalue=(new_value)
      if new_value == "true"
         @value = true
      else
         @value = false
      end
  end

I have a model with a boolean variable in the database and one added by attr_accessor:

In the model:

  attr_accessor :attrvalue

  validates(:dbvalue, inclusion: { in: [true, false], message: "%{value} is not a valid response"} )

  validates(:attrvalue, inclusion: { in: [true, false], message: "%{value} is not a valid response"} )

In the view:

    <%= form_for(@user) do |f| %>

      <%= f.select :dbvalue, {'' => nil, 'Yes' => true, 'No' => false}, {},  { :class => 'span1' } %>

      <%= f.select :attrvalue, {'' => nil, 'Yes' => true, 'No' => false}, {},  { :class => 'span1' } %>

    <% end %>

The dbvalue works, the attrvalue does not work and always throws the message attrvalue is not a valid response.

I assume that attrvalue is not a boolean. Can I force it to be a boolean? Alternately, is there another way to handle it?
