Question

我使用authlogic gem有一个非常简单的登录/注销代码。有时候，我会得到＆＃34; NoMethodError：未定义的方法`[] =＆＃39;为零：NilClass＆＃34;对于我的注销码 - 在user_session.destroy中。我从来没有设法自己重现它，但它发生了......

get 'logout' do
  user_session = UserSession.find
  if user_session
    user_session.destroy
    return {status: 200, message: 'Success'}
  else
    return {status: 400, message: 'No session to destroy'}
  end
end

回溯：

/home/admin/.rvm/gems/ruby-1.9.3-p392/gems/authlogic-3.3.0/lib/authlogic/session/session.rb:56:in update_session' /home/admin/.rvm/gems/ruby-1.9.3-p392/gems/activesupport-3.2.13/lib/active_support/callbacks.rb:418:in 运行 _509239456491140030__after_destroy_ 1525954531983478469 _callbacks＆＃39; /home/admin/.rvm/gems/ruby-1.9.3-p392/gems/activesupport-3.2.13/lib/active_support/callbacks.rb:405:in __run_callback' /home/admin/.rvm/gems/ruby-1.9.3-p392/gems/activesupport-3.2.13/lib/active_support/callbacks.rb:385:in _ run_after_destroy_callbacks＆＃39; /home/admin/.rvm/gems/ruby-1.9.3-p392/gems/activesupport-3.2.13/lib/active_support/callbacks.rb:81:in run_callbacks' /home/admin/.rvm/gems/ruby-1.9.3-p392/gems/authlogic-3.3.0/lib/authlogic/session/callbacks.rb:88:in after_destroy＆＃39; /home/admin/.rvm/gems/ruby-1.9.3-p392/gems/authlogic-3.3.0/lib/authlogic/session/existence.rb:50:in`stroy＆＃39;

UPDATE - 这是我的UserSession类实现：

class UserSession < Authlogic::Session::Base
  allow_http_basic_auth false

  def remember_me_for
    14.days
  end

  def self.last_request_at_threshold
    10.minutes
  end

  def perishable_token_valid_for
    10.minutes
  end

  disable_magic_states(true)
end

请帮助:( 谢谢！
