Ruby on rails 4 Rails 4.0和Desive的强大参数

我正在使用Rails 4.2和Desive。请求类型将始终为JSON。我的注册控制器如下所示

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

它产生的错误是控制器无法识别电子邮件和密码字段，并且总是返回错误，如：

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

---

发生这种情况是因为我在代码中写的愚蠢吗？请帮助

您的

配置\u注册\u参数

方法必须是这样才能工作的

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

如果您可以看到您发布的控制台内容，则它包含一个散列，其中包含

注册

作为密钥：

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

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