我使用紅寶石1.9.2和鋼軌3.我在運行我的應用程序時出現以下錯誤。未定義的方法`symbolize_keys!'爲2:Fixnum
錯誤:
undefined method `symbolize_keys!' for 2:Fixnum line #606 raised:
代碼:行號606
<%= f.text_field :total_amount ,:label=>'Grand Total',:value =>number_with_precision(0,2),:readonly=>true %>
應用程序跟蹤:
actionpack (3.0.0) lib/action_view/helpers/number_helper.rb:238:in `number_with_precision'
app/views/cashier/cashier/billing.rhtml:606:in `block (2 levels) in _app_views_cashier_cashier_billing_rhtml__3412897403160140582_59881040__1001215579093570677'
