NoMethodError：rspec測試中未定義的方法`symbolize_keys'

Question

以下是rspec中更新的錯誤：

  4) CustomersController GET customer page 'update' should be successful
     Failure/Error: post 'update', customer
     NoMethodError:
       undefined method `symbolize_keys' for "1":String
     # ./spec/controllers/customers_controller_spec.rb:38:in `block (3 levels) in <top (required)>'

rspec代碼：

it "'update' should be successful" do

  customer = Factory(:customer)      
  post 'update', customer
  response.should be_success
end

客戶控制器中的更新：

  def update
    @customer = Customer.find(params[:id])
    if @customer.update_attributes(params[:customer], :as => :roles_new_update)
      if @customer.changed
        @message = 'The following info have been changed\n' + @customer.changes.to_s
        @subject ='Customer info was changed BY' + session[:user_name]
        notify_all_in_sales_eng(@message,@subject)
      end  

      redirect_to session[('page'+session[:page_step].to_s).to_sym], :notice => 'Customer was updated successfaully!'
    else
      render 'edit', :notice => 'Customer was not updated!'
    end
  end

有關錯誤的任何想法？ 謝謝。

我不會詳細介紹RSpec，但我遇到了同樣的錯誤，這就是我為你的代碼糾正它的方法：

it "'update' should be successful" do
  customer = Factory(:customer)      
  post 'update', :id => customer.id
  response.should be_success
end

我認為你不能直接將你的對象提供給post方法，你必須在Hash傳遞它的id 。

（請注意，此代碼假定您的客戶存在於測試數據庫中，因此您的工廠必須create它。）
