validates preference of at least one param

I have a simple RESTful search scaffold that finds data in a separate model and controller.

[code] <h1>New search</h1>

<% form_for(@search) do |f| %>   <%= f.error_messages %>

  <p>     <%= f.label :category_id %><br />     <%= f.collection_select :category_id, Category.all, :id, :name, :include_blank => true %>   </p>   <p>     Age Range<br />     <%= f.text_field :minimum_age, :size => 3 %> -     <%= f.text_field :maximum_age, :size => 3 %>   </p>

  <p>     <%= f.submit 'Create' %>   </p> <% end %> [/code]

I would like to require at least one parameter in the search, be it a selected category, a minimum age, or a maximum age.

Then write a custom validation method.

Best,
