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? -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
