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
