Question

我正在使用Rails 4.2和devise.Request类型将永远是JSON.My注册控制器看起来像这样

class Users::RegistrationsController < Devise::RegistrationsController
  before_filter :configure_sign_up_params, only: [:create]

  def create
    if request.format(request) == "application/json"
      build_resource(sign_up_params)
      if resource.save
        render :json => {:success => "true", :message => "Thank You For Registering."}
      else
        render :json => {:success => "false", :message => resource.errors.full_messages}
      end
    else
      super
    end
  end

  protected

  def configure_sign_up_params
    devise_parameter_sanitizer.for(:sign_up) do |u|
      u.permit(:email, :password, :password_confirmation)
    end
  end

end

控制台中显示的参数如下：

 Parameters: {"email"=>"test123@gmail.com", "password"=>"[FILTERED]", "password_confirmation"=>"[FILTERED]", "registration"=>{"email"=>"test123@gmail.com", "password"=>"[FILTERED]", "password_confirmation"=>"[FILTERED]"}}

它产生的错误是控制器无法识别电子邮件和密码字段，并始终返回错误，如：

["Email can't be blank","Password can't be blank"]

这是否因为我在代码中写的任何愚蠢而发生？请帮助

你的configure_sign_up_params方法必须是这样的。

def configure_sign_up_params
  devise_parameter_sanitizer.for(:registration) do |u|
    u.permit(:email, :password, :password_confirmation)
  end
end

如果您可以看到控制台内容已发布的内容，则其中包含一个以registration为主键的哈希：

"registration"=>{"email"=>"test123@gmail.com", "password"=>"[FILTERED]", "password_confirmation"=>"[FILTERED]"}

Rails 4.0和Devise的强参数
