无法将 Fixnum 转换为字符串 - Devise/sessions 控制器问题

Question

所以这是我看到的错误：

TypeError in Devise/sessionsController#create

can't convert Fixnum into String

Application Trace | Framework Trace | Full Trace
app/controllers/application_controller.rb:21:in `set_current_user'

这就是 application_controller.rb 的样子：

    class ApplicationController < ActionController::Base
  helper :all
   helper_method :current_user, :logged_in?

  protect_from_forgery
  before_filter :set_current_user

  def set_xhr_flash
    flash.discard if request.xhr?
  end

  def correct_safari_and_ie_accept_headers
    ajax_request_types = ['text/javascript', 'application/json', 'text/xml']
    request.accepts.sort! { |x, y| ajax_request_types.include?(y.to_s) ? 1 : -1 } if request.xhr?
  end


  protected 

  def set_current_user
    Authorization.current_user = current_user
  end

end

救命！

Edit1：根据请求，这是日志文件的输出。

有人为此提出任何解决方案吗？

Answer 1

好吧，我终于找到了答案。数据库已损坏。一旦我转储了整个数据库，删除了数据库文件并重新创建了所有内容 - 我就可以开始了。

叹气

我只是希望我能找到一种方法来防止这种情况在生产中发生。

Answer 2

您确定以下内容位于正确的whatever_controller.rb中吗？

  before_filter :authenticate_user!

Answer 3

你把数据库密码设置为纯数字了吗？我的数据库密码在开发机上是111111，根据错误信息“can't conversion Fixnum into String”，我想我应该将数据库密码更改为非-数字“abcdef”并且成功了！
