自定义验证消息 [英] customize validation messages

问题描述

我想知道如何完全自定义验证消息，这就是我的代码的样子

i want to know how to fully customize validation messages, this is how my code looks like

user_profile.rb:-

user_profile.rb:-

validates: first_name, :presence => {:message => "First name can't be blank"}

但这给了我一条错误消息用户配置文件名字名字不能为空，我想要的是有一条错误消息名字不能为空.我四处寻找解决方案，我想我必须对 en.yml 文件进行一些更改，但我不知道该怎么做.有什么帮助吗?

but this gives me an error message user profile first name First name can't be blank and what i want is to have an error message First name can't be blank. I look around for solution and i think i have to do some changes in en.yml file, but i don't know what to do. Any help?

推荐答案

您有三个选择:

validate do |user|
  user.errors.add_to_base("First name can't be blank") if user.first_name.blank?
end

或

执行 user_profile.errors.full_messages 会给你 -> ["名字不能为空"]

Doing user_profile.errors.full_messages will give you -> ["First Name can't be blank"]

validates: first_name, :presence => {:message => "can't be blank"}

或

# config/locales/en.yml
en:
  activerecord:
    attributes:
      user_profile:
        first_name: "First name"
    errors:
      models:
        user_profile:
          attributes:
            first_name:
              blank: "can't be blank"
