I have the following piece of code
%br
= f.label :active, \'Status\'
= f.select :active, [\'Active\',\'Inactive\']
Symbol :active is a boolean
A small extension of the earlier answer, if you're using a dropdown.
I needed to use "options_for_select." Also, ":selected" stores the value for the next time you return to the form.
<%= f.select(:active, options_for_select([['Active', true], ['Inactive', false]], {:selected => @symbol.active}),:prompt => "Select") %>
