Rails - May 2006 - Creating Multiple Child objects on a single form

I''ve been trying to solve this for the last few hours and I have 
something that is working now but I''m curious if there isn''t a
better
''right'' way to do it since this seems a bit of a cludge to me,
but I
haven''t find a better way to make it work.

The models are as follows:

Goals, which have multiple objectives.
Goals also have multiple evaluations of those objectives through status 
models.

So, I''m trying to create a form for doing the evaluations, which
ideally
would allow you to set the status of all objectives in a single view.

My view looks like this (trimmed down a bit for easier posting):

    <% for objective in @goal.objectives %>
       <label for="status<%= objective.number
%>_status">Status:</label>
         <%= text_field ''status'' + objective.number.to_s,
''status'' %>
         <%= hidden_field ''status'' + objective.number.to_s,
''objective_id'', :value => objective.id %>
    <% end %>

    <label for="evaluation_date">
            Evaluation Date:</label>
    <%= date_select ''evaluation'',
''evaldate'', :order => [:day, :month,
:year ] %>
    <label for="evaluation_comment">
            Comments:</label>
            <%= text_area ''evaluation'',
''comment'' %>

This produces a set of ''status'' objects like status1, status2,
status3
in params, which I then loop through again in the create function in my 
evaluations controller:

  def create
    @evaluation = Evaluation.new(params[:evaluation])
    @goal = Goal.find_by_id(params[:goal_id])
    if @evaluation.save
      for objective in @goal.objectives
        @evaluation.statuses.create(params[''status'' + 
objective.number.to_s])
      end
      flash[:notice] = ''Evaluation was successfully created.''
      redirect_to :action => ''show'', :controller =>
''goals'', :id =>
@goal
    else
      render :action => ''new''
    end
  end

So, this works fine, but I''m curious if there is a better way to do 
this.
