Rails - 模型中的 real_create_a_version

我正在使用 Rails 3 Vestal Versions gem： https://github.com/lailsonbm/vestal_versions

我想要创建一些逻辑来确定是否/何时在模型更新时创建新版本。根据规格，我做了：

class Note < ActiveRecord::Base
    versioned :if => :really_create_a_version?

  def really_create_a_version
    Rails.logger.debug 'really_create_a_version really_create_a_version really_create_a_version really_create_a_version - START'
    record.inspect
    @note = Note.find(32)
    Rails.logger.debug 'really_create_a_version really_create_a_version really_create_a_version really_create_a_version - END'
  end

end

但这不起作用，我收到以下错误：

NoMethodError (undefined method `really_create_a_version?' for #<Note:0x155c39a28>):
  app/controllers/notes_controller.rb:124:in `update'

有什么建议或想法吗？ thxs

更新

有条件的版本创建。版本化方法现在接受 :if 和 :unless 选项。每个都需要一个代表实例方法或过程的符号，将对其进行评估以确定是否在更新后创建新版本。还可以给出包含符号和过程的任意组合的数组。用户类< ActiveRecord::基础版本控制：if => ：真的创建版本吗？结尾

I'm using the Rails 3 Vestal Versions gem: https://github.com/lailsonbm/vestal_versions

I'd like to create some logic to determine if/when to create a new version on a model update. Per the specs, I did:

class Note < ActiveRecord::Base
    versioned :if => :really_create_a_version?

  def really_create_a_version
    Rails.logger.debug 'really_create_a_version really_create_a_version really_create_a_version really_create_a_version - START'
    record.inspect
    @note = Note.find(32)
    Rails.logger.debug 'really_create_a_version really_create_a_version really_create_a_version really_create_a_version - END'
  end

end

But that doesn't work, I get the following error:

NoMethodError (undefined method `really_create_a_version?' for #<Note:0x155c39a28>):
  app/controllers/notes_controller.rb:124:in `update'

Any suggestions or ideas? thxs

UPDATE

Conditional version creation. The versioned method now accepts :if and :unless options. Each expects a symbol representing an instance method or a proc that will be evaluated to determine whether or not to create a new version after an update. An array containing any combination of symbols and procs can also be given.
class User < ActiveRecord::Base
versioned :if => :really_create_a_version?
end
