我的用户模型中有一堆调用，这些调用是在用户创建（成功写入数据库）之后触发的。现在我注意到它们似乎不再被触发了。
before_create :generate_access_token
after_commit :logging, on: :create
after_commit :send_welcome_email, :create_settings, on: :create
我刚刚添加了日志记录方法，如果方法被触发，它只会输出一条消息，但它没有显示在日志中。
def logging
puts "xoxoxo logging user #{self.id} xoxoxo"
end
我在Heroku上使用Ruby 2.1.2和Rails 3.2.21。
我怎样才能让他们再次工作？
这是User._commit_callbacks
