Topic: Using non associated models data in a form

Is it possible to access another models attributes without having associations? For example I want to create a Prediciton record via a form using the fixture models attributes

    <%= form_for :prediction do |f| %>
    <%= f.fields_for :fixtures, @fixtures do |builder| %>

    <%= builder.text_field :home_team %> VS <%= builder.text_field :away_team %><%= f.text_field :home_score %><%= f.text_field :away_score %><br>

    <% end %>
    <% end %>

how would i get the attributes of the fixture model without associating the two models?
