请多多包涵，因为我对 Rails（尤其是 Rails 3）有点陌生，对此我有点难过。基本上我想在我的应用程序中使用 RSpec 测试我的 CustomersController。当我执行我的规范试图在我的控制器中执行创建操作时，我收到了这个错误，我不知道为什么：

1) CustomersController as guest should render new template when executing create action with invalid model
    Failure/Error: post :create, :customer => model
    protected method `reject' called for #<Customer:0x0000010611c400>

现在我真的很抱歉，但这里有很多代码要遵循。首先是我的宝石。

mongoid (2.0.0.beta.16)
mongoid-rspec (1.2.0)
...
rspec (2.0.0.beta.19)
rspec-core (2.0.0.beta.19)
rspec-expectations (2.0.0.beta.19)
rspec-mocks (2.0.0.beta.19)
rspec-rails (2.0.0.beta.19)
...
rails (3.0.0.rc)
...
recaptcha (0.2.3)

现在，我的CustomersController定义如下：

class CustomersController < ApplicationController

  respond_to :html
  before_filter :authenticate_customer!, :except => [ :new, :create ]

  def new
    @customer = Customer.new
  end

  def create
    @customer = Customer.new(params[:customer])
    if verify_recaptcha(:model => @customer, :message => "Image verification failed.  Please try again.") && @customer.save 
      flash[:notice] = "Your account has been created successfully"
    end
    respond_with @customer
  end

  def show
  end
end

这是我的客户模型：

class Customer
  include Mongoid::Document
  devise :database_authenticatable, :recoverable, :rememberable,
    :trackable, :validatable

  field :first_name
  field :last_name
  field :email
  field :roles, :type => Array, :default => [ 'User' ]

  embeds_many :servers

  validates_presence_of :first_name
  validates_presence_of :last_name
  validates_presence_of :email
  validates_presence_of :roles

  validates_uniqueness_of :email

  attr_accessible :first_name, :last_name, :email,
                  :password, :password_confirmation

  def role?(role)
    return !!self.roles.include?(role.to_s.camelize)
  end

end

最后，这是我的规格：

describe CustomersController, "as guest" do
  include Devise::TestHelpers

  it "should render new template when executing new action" do
    get :new
    response.should render_template(:new)
  end

  it "should render new template when executing create action with invalid model" do
    model = Customer.new(:first_name => "Test", :last_name => "user")
    post :create, :customer => model
    response.should render_template(:new)
  end
end

事实证明，在我的每个测试中，我都必须传递一个元组而不是实际的模型对象。我切换到使用 factory_girl 来创建我的模型对象，然后attributes_for在每个模型对象上调用该方法。我将该结果传递给create操作，一切都按预期工作。
