Question

我正在使用Test :: Unit对我的rails 3应用程序运行功能测试，该应用程序使用Devise和CanCan来帮助管理用户。但是，当我对我的contacts_controller进行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时，请求失败，然后停止，然后导致测试失败。

有人会知道为什么会这样吗？

联系测试

test "should create contact" do
  assert_difference('Contact.count') do
    post :create, 
      :contact => {
        :first_name => "John",
        :last_name => "Doe",
        :email_address => "test@test.com",
        :phone_number => "1234567890"
      },
      :camp_id => camps(:bolo).uri
  end

  assert_response :created
  assert_not_nil assigns(:contact)

  get :show, 
    :id => assigns(:contact).to_param,
    :camp_id => camps(:bolo).uri

  assert_response :success
end

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

授权控制器

class AuthorizedController < ApplicationController
  before_filter :authenticate_user!
  check_authorization
  load_and_authorize_resource

  rescue_from CanCan::AccessDenied do |exception|
    flash[:error] = exception.message
    respond_to do |format|
      format.html { redirect_to new_user_session_path, :status => :unauthorized }
      format.xml { render :xml => "...", :status => :unauthorized }
    end
  end
end

CanCan能力

def initialize(user)
    user ||= User.new # guest user (not logged in)

    if user.role? :admin
      can :manage, :all
    elsif user.role? :account_admin
      can [:show, :update, :destroy, :create], Camp do |camp|
        user.is_linked_to_camp?(camp)
      end

      can :manage, Contact do |contact|
        user.is_obj_linked_to_camp?(contact)
      end
    else
      cannot :manage, :all
    end
end

原来是我的代码中存在错误。我的测试未更新为在Contacts模型中考虑新架构。
