AASM Gem被Rails打破2.3.2？

Question

是否有人在Rails 2.3.2中使用AASM状态机Gem有任何问题？它对我来说很好，但是现在给我一个NoMethodError

NoMethodError (undefined method `state' for #<Comment:0x25cb8ac>):
  /usr/local/lib/ruby/gems/1.8/gems/rubyist-aasm-2.0.5/lib/persistence/active_record_persistence.rb:231:in `send'
  /usr/local/lib/ruby/gems/1.8/gems/rubyist-aasm-2.0.5/lib/persistence/active_record_persistence.rb:231:in `aasm_read_state'
  /usr/local/lib/ruby/gems/1.8/gems/rubyist-aasm-2.0.5/lib/persistence/active_record_persistence.rb:135:in `aasm_current_state'
  /usr/local/lib/ruby/gems/1.8/gems/rubyist-aasm-2.0.5/lib/persistence/active_record_persistence.rb:156:in `aasm_ensure_initial_state'
 app/controllers/comments_controller.rb:12:in `create'

下面是我的模型中使用AASM的相关代码：

class Comment < ActiveRecord::Base
  include AASM
  belongs_to :post          
  after_create :spam_check

  aasm_column :state
  aasm_initial_state :submitted
  aasm_state :submitted
  aasm_state :approved
  aasm_state :rejected

  aasm_event :ham do
    transitions :to => :approved, :from => [:submitted, :rejected]
  end

  aasm_event :spam do
    transitions :to => :rejected, :from => [:submitted, :approved]
  end     

  private          
  def spam_check
    # Invoke Askismet to see if the comment is spam...
  end
end

注意，我的comments表中有comments列。

• 知道它为什么不再起作用了吗？

Answer 1

你需要在你的评论表中有一个名为'state‘的字段。您使用aasm_column :state定义了它。这不是Rails 2.3.2错误！:D

Answer 2

从aasm主页上看，在写文章的时候，有一个更新即将到来.

在组上有一个小小的讨论--我不知道这是否有帮助。

执行

gem list .*aasm --remote

抛出一堆推荐信：

aasmith-yodlee (0.0.1.20090301132701)

它怀疑一些或全部"dvdplm-“、”工厂实验室-“和"runcoderun-”可能是git叉。你可能会发现一个或多个解决了你的问题。
