How to insert a null value into DB using a radio_button with form_for
Hi, I''m trying to add a third option for a filter using a radio button. It''s the old null-value-for-a-boolean story. Basically i''d like to add another radio button labelled "No Filter" which would insert a null value into the database when selected. Here is my first attempt. The third button is showing up, but the null value is not being inserted. What am I missing? <div class="new-partner-form"> <%= form_for [:admin, matching_profile.partner, matching_profile], :html => {:id => "edit_profile", :multipart => true} do |f| %> <div class="rounded-block semi-wide clear"> <h4>Military Service</h4> <%= f.radio_button :served_in_us_army, false %> <%= label :served_in_us_army, ''NO'', {:style => ''display:inline''} %> <%= f.radio_button :served_in_us_army, true %> <%= label :served_in_us_army, ''YES'', {:style => ''display:inline''} %> <%= f.radio_button :served_in_us_army, nil %> <%= label :served_in_us_army, ''No Filter'', {:style => ''display:inline''} %> <%= f.error_message_on :served_in_us_army %> </div> -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

You''ll need to turn the value back into a nil server-side.
