ruby-on-rails - 无方法错误 :undefined method `symbolize_keys' in rspec test

Question

这是rspec中更新的错误:

  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 代码:

it "'update' should be successful" do

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

客户 Controller 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

关于错误的任何想法？谢谢。

我不会详细介绍 RSpec，但我遇到了同样的错误，这就是我为您的代码更正它的方法:

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

我认为您不能直接将您的对象提供给 post方法，你必须通过它的 id如 Hash反而。

(也请注意，此代码假定您的客户存在于测试数据库中，因此您的工厂必须 create 它。)
