在Rails中检查数据库时没有任何区分大小写

Question

我想在控制器中检查没有区分大小写的数据库。如果它不存在我想保存它，否则我想显示已经存在的通知。我的控制器是

def party_order_create
@party_order = PartyOrder.find_by(party_order_params)
if @party_order.present?
  flash[:success] = "Party Not Saved"
  redirect_to :action => "party_order_new"
else @party_order  = PartyOrder.new(party_order_params)
  @party_order.save
  flash[:success] = "Party Saved"
  redirect_to :action => "party_order_new"
end

end`

我的模特是，

validates_uniqueness_of :party_order_list, :case_sensitive => false

它运作正常..但我得到了聚会保存通知..   请有人帮助我
