Rails 3 w/Devise/CanCan：加载用户时POST/PUT请求失败？

Question

我正在使用Test :: Unit运行功能测试，针对使用Devise和CanCan来帮助管理用户的我的rails 3应用程序。然而，当我向我的contacts_controller发布POST或PUT时，我在请求中遇到了一个奇怪的问题。当控制器从数据库加载用户，然后停止，然后导致测试失败时，请求失败。

有人会想到为什么会发生这种情况吗？

test "should create contact" do 
    assert_difference('Contact.count') do 
    post :create, 
     :contact => {

联系控制器

class Camp::ContactsController < AuthorizedController 
    def create 
    @contact = @camp.contacts.build(params[:contact]) 

    respond_to do |format| 
     if @contact.save 
     format.html { render :text => "contact created!", :status => :created } 
     format.xml {render :xml => @contact, :status => :created, :location => @contact} 
     else 
     format.html { render :action => "new", :status => :bad_request } 
     format.xml { render :xml => @contact.errors, :status => :bad_request } 
     end 
    end 
    end 
end

def initialize(user)

    if user.role? :admin

    elsif user.role? :account_admin 
     can [:show, :update, :destroy, :create], Camp do |camp|

原来是有人在我的代码中的错误。我的测试未更新以解决“联系人”模型中的新架构。
