Validates preference of at least one param

Rails
1

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

<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 %>

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

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.
