Ruby on rails 在heroku上的rails中充当类的实例

创建新帐户时，我有类似于以下的代码作为创建后回调：

def after_account_create
  new_account = self
  logger.info( '%%%%%%%%%%%%%%%%%%%%%     account is = ' + new_account.inspect)          
  assessment = Assessment.new :title => "Cake baking", :description => "Every day we bake fresh cakes to sell in our shop. This is our assessment of the risks involved in this process.", :account_id => new_account.id
  assessment.save!
end

当我在我的开发环境（乘客/博士后）上运行此功能时，它运行良好-每次个人注册并创建新帐户时，它都会创建一个分配给该个人帐户的新评估

但是，当我在我的生产环境（Heroku上的瘦Web服务器）上运行此操作时，每次有个人注册并创建一个新帐户时，它都会创建一个新的评估，但分配给前一个人的帐户

以下是第二个人创建帐户时两个日志中的示例：

发展

%%%%%%%%%%%%%%%%%%%%%     account is = #<Account id: 97, name: "Eric Clapton", plan: "Partnership", billing_zip: nil, no_of_users: 1, no_of_assessments: nil, id_of_admin_user: 90, created_at: "2012-04-05 14:58:54", updated_at: "2012-04-05 14:58:56">
(0.2ms)  BEGIN
SQL (1.5ms)  INSERT INTO "assessments" ("account_id", "created_at", "description", "title", "updated_at") VALUES ($1, $2, $3, $4, $5) RETURNING "id"  [["account_id", 97], ["created_at", Thu, 05 Apr 2012 10:58:56 EDT -04:00], ["description", "Every day we bake fresh cakes to sell in our shop. This is our assessment of the risks involved in this process."], ["title", "Cake baking"], ["updated_at", Thu, 05 Apr 2012 10:58:56 EDT -04:00]]

%%%account is=#这可能是请求之间缓存的内容吗

更新2:
事实上正是这样。正在会话之间缓存当前_租户值。我必须向accounts\u controller添加一个方法，该方法在每次为新创建的帐户创建帐户时定义当前租户值。
它在您的开发环境中与生产设置的关系如何？我怀疑cache_classes=false会导致代码忘记意外记忆的内容。您发布到实际代码中的内容有多相似？@BetjaminRichards为什么不在保存回调后写入此内容，并检查它是否表现出相同的行为，即行为如何weird@BetjaminRichards我同意@dbenhur，我怀疑设置
cache\u classes=false
是错误的原因
%%%%%%%%%%%%%%%%%%%%%     account is = #<Account id: 2, name: "jack cale", plan: "Partnership", billing_zip: nil, no_of_users: 1, no_of_assessments: nil, id_of_admin_user: 2, created_at: "2012-04-05 14:46:54", updated_at: "2012-04-05 14:46:56">
