自定义rails错误消息

Question

我在rails4中为验证器定制消息时遇到了问题。我有设计注册系统的应用程序。我的模型中有一些验证器：

 validates :name, length: {maximum: 45}, presence: true
 validates :surname, length: {maximum: 45}, presence: true
 validates :phone, :phony_plausible => true, presence: true
 validates :company_name, length: {maximum: 100}, presence: true
 validates :address, length: {maximum: 50}, presence: true
 validates :city, length: {maximum: 70}, presence: true
 validates :zip_code, presence: true, length: {is: 6}
 validates :nip, nip: true

当用户在姓名输入中留空时，会出现一条消息：

Name can't be blank

当我向我的验证器添加消息选项时：

  validates :name, length: {maximum: 45}, presence: {message: "Imię nie może być puste"}

我有以下消息: Name Imięnie może byćpuste。我不想在我的消息中出现这个名字。该怎么做呢？

在您的配置文件/locales/en.yml中

en: activerecord: attributes: [model_name_goes_here]: [attribute_name_goes here]: "" errors: models: [model_name_goes_here]: attributes: [attribute_name_goes_here]: blank: "Email can't be blank"

示例：

en: activerecord: attributes: user: email: "" errors: models: veteran: attributes: email: blank: "Email can't be blank"

例如，它不会显示“电子邮件不能为空”，而会显示“不能为空”。实际上，您是在用一个等同于空字符串的别名替换"name:“。您可以将" name：“设置为name："Your name”

en: activerecord: attributes: user: name: "Your name"
