只是我还是全局 RSpec 行为,当我命名我的 rails 模型范围:public时,从这个模型初始化对象,然后存根这个对象 Rspec 失败

class DocumentName < ActiveRecord::Base

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

没什么特别的,Rails 应用程序有效

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)>'

...而且最有趣的是,在这种情况下,我没有在那个范围内做任何事情。

但是,如果我将此范围命名为:public例如:are_public

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

...一切都通过 O_O

Rails 3.2.11 (but same thing on any 3.2.x)
Ruby ruby-2.0.0-rc1 ( but same for any ruby-1.9.3)

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。
