自定义 ActiveModel full_messages

Question

我想从我的自定义验证消息中删除该属性并只显示该消息，而不是

School Please Provide Your School Name

我要return

Please Provide Your School Name

在我这里的模型中设置

validates :school, presence: { message: 'Please Provide Your School Name' }

消息被 return 编辑为 JSON 响应。

查看full_messages方法

# File activemodel/lib/active_model/errors.rb, line 348
def full_messages
  map { |attribute, message| full_message(attribute, message) }
end

我可以用

覆盖它吗

# File activemodel/lib/active_model/errors.rb, line 348
def full_messages
  map { |attribute, message| full_message(message) }
end

我试过了

module ActiveModel
  class Errors
    def full_messages
      map { |attribute, message| full_message(message) }
    end
  end
end

位于/lib/active_model/errors.rb

但是当我尝试运行我的测试时 (rspec) 我得到了错误

/home/richardlewis/.rvm/gems/ruby-2.2.0@lnf_api/gems/activemodel-4.2.0/lib/active_model/validations.rb:297:in `initialize': wrong number of arguments (1 for 0) (ArgumentError)

我将文件加载到 application.rb

config.autoload_paths += %W(#{config.root}/lib)

请问我该如何解决？

谢谢

控制器

class RegistrationsController < Devise::RegistrationsController
skip_before_action :verify_authenticity_token
respond_to :json

def create
 @user = User.new(registration_params)
   if @user.valid?
     @user.save
     render json: { message: I18n.t("devise.registrations.signed_up_but_unconfirmed") }, status: 201
   else
     render json: { message: @user.errors.full_messages }, status: :unprocessable_entity
   end
end

protected
def registration_params
  json_params = ActionController::Parameters.new(JSON.parse(request.body.read))
  json_params.require(:user).permit(:username, :school, :email, :password, :password_confirmation)
 end
end

Answer 1

full_message 需要两个参数 attribute 和 message.

更新：避免猴子修补并编辑您的语言环境文件以使其具有类似内容：

en:
  errors:
    format: "%{message}"
