在Ruby On Rails中对选择进行排序

ROR newby问题:

我有一个控制器有以下动作:

# GET /organisations/new
# GET /organisations/new.xml
def new
  @organisation = Organisation.new
  @organisationtypes = Organisationtype.find(:all) 

  respond_to do |format|
    format.html # new.html.erb
    format.xml  { render :xml => @organisation }
  end
end

以及在Organizations/new视图中选择OrganizationType,例如:

<p>
<%= f.label :organisationtype %><br />
<%= select "organisation", "organisationtype_id", Organisationtype.find(:all).collect {|p| [ p.organisationtype, p.id ] }, {:include_blank => true } %>
</p>

谢谢你的时间
