切换到Rails 4.1时的错误 - `method_missing':未定义的方法`whitelist_attributes ='表示ActiveRecord :: Base:Class(NoMethodError)

  • match
  • list
  • io
  • config
  • 日志
  • ruby

    • 从Rails 4.0切换到Rails 4.1时,我收到此错误:

    activerecord-4.1.8/lib/active_record/dynamic_matchers.rb:26:in `method_missing': undefined method `whitelist_attributes=' for ActiveRecord::Base:Class (NoMethodError)

    我没有使用 attr_accessible或attr_protected在我的应用程序的任何地方,所以我想知道为什么我有一个问题.

    转移到Rails 4.0时,我已经放了我的application.rb:

    配置/ application.rb中:

    config.active_record.whitelist_attributes = false

    完整的错误日志是:

    我真的迷失在这里,因为大多数人都有与我有关的bug建议使用gem'en protected_attributes but I don't want to use it as I don't have anyattr_accessible norattr_protected`.

    知道这个bug来自哪里？

    • 您可以安全地删除 config.active_record.whitelist_attributes = false

      从您的应用配置文件.

      并删除模型类中的所有white_list_attributes.

      干杯,
