Rails 4身份validation
哪个gem最适合在Rails 4中进行身份validation？ 我尝试使用设计，但我遇到了问题。

ActiveModel::MassAssignmentSecurity已从ActiveModel中取出。 但是设计使用attr_accessible ，因此要使用它，只需在你的Gemfile中添加以下gem并尝试再次加载。
gem 'protected_attributes'
编辑：
现在设计支持rails-4。 在Gemfile中包含它。
gem 'devise', '3.0.0.rc'
编辑 ：现在有一个Devise版本支持Rails 4： Devise 3.0.0.rc
上一个答案 ：我最终做的就是让它工作得很好……
-
在Gemfile中：gem’devise
gem 'devise', github: 'plataformatec/devise', branch: 'rails4' -
在生成的模型中，删除
attr_accessible东西。 -
为Devise启用强参数而不是attr_accessible。 为此，请使用该内容创建一个新的initiliazer：
DeviseController.class_eval do def resource_params unless params[resource_name].blank? params.require(resource_name).permit(:email, :password, :password_confirmation, :remember_me) end end end
请不要在项目中使用带设计的attr_accessible ，请按以下方式使用accesssibles –
就像我们有attr_accessible：email，：password，：password_confirmation，：remember_me，然后我们可以出于安全原因在私有方法中转换它们：
private def user_params params.require(:user).permit(:email, :password, :password_confirmation, :remember_me) end
如果您遇到Devise的问题，那么尝试“Authlogic”也是一个很好的身份validationgem。
你可以使用gem’authlogic”~3.2.0’，这是支持Rails 4.0的最新版本
Ruby工具箱有一个最受欢迎的列表： http ： //ruby-toolbox.com/categories/rails_authentication.html
这真的取决于你需要gem做什么。 有很多选择，而Devise绝对是顶级的。 我建议清理Thoughtbot（ https://github.com/thoughtbot/clearance ）。 它经过了很好的测试，并且经常更新。 对我来说，当我需要核心身份validationfunction而不是像Devise这样的gem所带来的所有其他东西时，它非常有用！
在GemFile中编写gem“devise”，“〜> 3.0.0.rc”。 并按照https://github.com/plataformatec/devise上提供的说明进行操作
我希望你的问题能够得到解决。
我已经修复了导轨4中的isuue。您现在可以毫不费力地实现它。
只需将gem’devise’添加到您的Gemfile中并进行捆绑。
谢谢
