belongs_to :employee

model - ticket.rb

belongs_to :owner, :class => 'Owner'
accepts_nested_attributes_for :owner, :allow_destroy => true

controller - tickets_controller.rb
  def new
    @ticket = Ticket.new
    @ticket.owner.build
    respond_to do |format|
      format.html # new.html.erb
      format.xml { render :xml => @ticket }
    end
  end

tickets view - new.html.erb
<% form_for(@ticket) do |f| %>
  <%= f.error_messages %>
  <p>
    <%= f.label :subject %><br />
    <%= f.text_field :subject %>
  </p>
  <p>
    <%= f.label :description %><br />
    <%= f.text_area :description, :rows => 10, :cols => 48 %>
  </p>
  <p>
    <%= f.label :due_date %><br />
    <%= f.text_field :due_date, :id => 'ticket_date_select' %>
  </p>
  <p>
    <%= f.label :ticket_status_id, "Set Ticket Status" %><br />
    <%= collection_select(:ticket, :ticket_status_id,
TicketStatus.all, :id, :status_type)%>
  </p>
  <p>
    <%= f.label :priority_id, "Ticket Priority" %><br />
    <%= collection_select(:ticket, :priority_id,
Priority.all, :id, :priority_type)%>
  </p>
  <% f.fields_for :owner do |owner_form|%>
      <%= owner_form.hidden_field :ticket_id, :value => @ticket.id %>
      <%= owner_form.hidden_field :employee_id, :value =>
current_employee.id %>
  <% end %>
  <p>
    <%= f.submit 'Create' %>
  </p>
<% end %>
