Rails 4.0 和 Devise 的强大参数

Question

我正在使用 Rails 4.2，devise.Request 类型将始终是 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，并且总是 returns 错误，如：

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

会不会是我在代码中写的愚蠢导致的？请帮忙

Answer 1

您的 configure_sign_up_params 方法必须像这样才能起作用。

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，它包含一个以 registration 作为键的散列：

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