自定义ActiveModel full_messages

时间:2015-03-11 11:29:32

标签: ruby-on-rails ruby rspec activemodel

我想从自定义验证消息中删除该属性,只显示消息,而不是

School Please Provide Your School Name

我想返回

Please Provide Your School Name

在我的模型中设置

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

消息以JSON响应的形式返回。

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

我试过这个

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(rspec)时,我收到了错误

/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)

我在application.rb中加载文件

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

我该如何解决这个问题?

由于

修改

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

full_message需要两个参数attributemessage

更新:避免猴子修补并编辑您的语言环境文件,例如:

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