Question

我刚刚在我的应用中配置了强参数，一切似乎都很好。但我的设计登录失败了。我仍然可以注册一个用户，这将登录用户。我在设计3.1.1

我添加到application_controller：

   before_filter :configure_permitted_parameters, if: :devise_controller? 

     protected
      def configure_permitted_parameters
        devise_parameter_sanitizer.for(:sign_in) { |u| u.permit(:email, :password, :remember_me) }
        devise_parameter_sanitizer.for(:sign_up) { |u| u.permit(:username, :email, :password) }
      end

在我的模特中

   devise :database_authenticatable, :registerable,
     :recoverable, :rememberable, :trackable, :validatable, :token_authenticatable, :invitable, :invite_for => 2.weeks, :authentication_keys => [:username]

我的日志中有一个DEPRECATION WARNING：devise：token_authenticatable已弃用。不确定这是不是问题？

我尝试在会话新视图中输出资源错误对象，但没有错误!!

Answer 1

您在设计模型中使用用户名作为身份验证模式

:authentication_keys => [:username]

在登录时，您需要有用于身份验证的电子邮件。尝试从

更改允许的参数

 devise_parameter_sanitizer.for(:sign_in) { |u| u.permit(:email, :password, :remember_me) }

到

devise_parameter_sanitizer.for(:sign_in) { |u| u.permit(:username, :password, :remember_me) }

同时修改config / initializers / devise.rb：

config.case_insensitive_keys = [ :email, :username ]
config.strip_whitespace_keys = [ :email, :username ]

如果您想使用用户名或密码登录，请查看此链接： https://github.com/plataformatec/devise/wiki/How-To:-Allow-users-to-sign-in-using-their-username-or-email-address

应用强参数后，设计完成401在1ms内未授权
