Rails I18n 接受_nested_attributes_for 和 error_messages_for [英] Rails I18n accepts_nested_attributes_for and error_messages_for

问题描述

我有两个模型

class SurveyResponse
  has_many :answers, :class_name => SurveyResponseAnswer.name
  accepts_nested_attributes_for :answers
end

class SurveyResponseAnswer
  belongs_to :survey_response
  validates_presence_of :answer_text
end

在我的嵌套表单中，如果验证失败，我会在屏幕上显示此错误:

In my nested form if validation fails I get this error displayed on the screen:

答案答案文本不能为空"

"answers answer text can't be blank"

我已经使用 rails I18n 成功地自定义了我的属性名称.它的行为并不完全符合我的预期.下面的yml文件不影响error_messages_for中属性名的打印方式

I've customized my attribute names somewhat successfully using rails I18n. It doesn't behave exactly how I would expect though. The yml file below doesn't affect how the attribute name is printed in error_messages_for

en: 
  activerecord:
    models:
      survey_response:
        answers: "Response"

但如果从脚本/控制台我尝试
SurveyResponse.human_attribute_name("答案")

But if from script/console I try
SurveyResponse.human_attribute_name("answers")

我得到了响应"的预期结果.

I get the expected result of "Response".

我想做的是让验证错误消息说:

What I'd like to do is have the validation error message say:

响应答案文本不能为空".有什么想法我需要解决的吗?

"Response answer text can't be blank". Any ideas what I need to fix?

推荐答案

试试这个:

en: 
  activerecord:
    models:
      survey_response:
        answers:
          answer_text: "Response"

我正在使用 Rails 3，这对我有用(我的 i18n 文件有点不同，使用属性"而不是模型.我不知道这是否适用于 2.3)

I am using Rails 3 and this is working for me (my i18n file is a bit different, using "attributes" instead of models. I don't know if this works in 2.3)

en: 
  activerecord:
    attributes:
      survey_response:
        answers:
          answer_text: "Response"

在此之前，我试图在 yml 中创建一个名为answers_answer_text"的属性，但它不起作用.

Before that I was trying to create a attribute in the yml called "answers_answer_text" but it was not working.

希望这能解决您的问题.

I hope this solves your issue.
