RSpec讨厌Rails范围,命名为:public,当存根对象时

Question

它只是我还是全局RSpec行为,当我命名我的rails模型范围时:public,从该模型初始化对象,并且存根此对象Rspec失败

class DocumentName < ActiveRecord::Base

  scope :public,    lambda{where( public: true) }  #line 3
end

没什么特别的,Rails应用程序可行

DocumentName.public  # => [ #DN, #DN, #DN... ]
# SELECT `document_names`.* FROM `document_names` WHERE `document_names`.`public` = 1

但是RSpec失败了

describe DocumentName do
  let(:resource){DocumentName.new}  
  it do
     resource.stub(:name).and_return('foo')   #line 16
     resource.save.should be true
  end
end

 Failure/Error: resource.stub(:name).and_return('foo')
 ArgumentError:
   wrong number of arguments (1 for 0)
 # ./app/models/document_name.rb:3:in `block in <class:DocumentName>'
 # ./spec/models/document_name_spec.rb:16:in `block (2 levels) in <top (required)>'

......最有趣的是,在这种情况下,我没有对该范围做任何事情.

但是,如果我将此范围命名为其他内容,:public例如:are_public::

class DocumentName < ActiveRecord::Base
  scope :are_public,    lambda{where( public: true) }
end

......一切都通过O_O

private并且public是Ruby的访问修饰符:

class User
  private
  def some_private_method
  end

  public
  def some_public_method
  end
end

虽然它们看起来像关键字,但它们实际上是方法调用.覆盖它们并不是一个好主意.
