Rails, radio button not storing value in boolean field on DB

Question

I have created a small form to allow users submit 'opinions'. This can be positive or negative. I got a 'positive' boolean field on the DB. This should be true if positive or false if negative.

=form_for @opinion do |f|
        = f.hidden_field :event_id
        %p
          =f.radio_button(:positive, :checked => (:positive == 1))
          =f.label :true, 'Positive'
          =f.radio_button(:positive, :checked => (:positive == 0))
          =f.label :false, 'Negative'
        %p
          =f.label 'Body'
          =f.text_area :body
        =f.submit

However, everything is stored right but the positive field. What am I doing wrong?

This is what I get

 Parameters: {"utf8"=>"✓", "authenticity_token"=>"EgFB9zohTA93ClNAQpS0qcsEivSCe1imjDUuw/e/YYA=", "opinion"=>{"event_id"=>"31", "positive"=>"{:checked=>false}", "body"=>"asdasasdasd"}, "commit"=>"Create Opinion", "locale"=>"en"}

Why don't you just use a simple checkbox? if checked than positive, if not then negative. or whatever — Zippie

Rails will add 'checked' when your attribute's value is equal to the supplied value

=f.radio_button :positive, 1
=f.label :true, 'Positive'
=f.radio_button :positive, 0
=f.label :false, 'Negative'

please check the doc

Remove the :checked stuff. If your database field is a boolean, than rails form_for knows which f.radio_button to check.
