How to translate active record model validations
提问by John
When I submit a form with an error in it, it returns an error message. How can I translate these error messages with i18n? I already have translation for all the other texts in my views, so I know how l18n works in Rails. I now get this:
当我提交一个包含错误的表单时，它会返回一条错误消息。如何使用 i18n 翻译这些错误消息？我已经在我的视图中翻译了所有其他文本，所以我知道 l18n 在 Rails 中是如何工作的。我现在明白了：
2 errors prohibited this user from being saved:
Email translation missing: nl.activerecord.errors.models.user.attributes.email.blank
Email translation missing: nl.activerecord.errors.models.user.attributes.email.blank
I want to translate both the title and the errors.
我想翻译标题和错误。
回答by tbuehlmann
The translation for the title would be:
标题的翻译是：
nl:
activerecord:
errors:
template:
header:
one: "1 error prohibited this %{model} from being saved"
other: "%{count} errors prohibited this %{model} from being saved"
body: "There were problems with the following fields:"
For translating the error messages, Rails will use the following order of translations:
为了翻译错误消息，Rails 将使用以下翻译顺序：
activerecord.errors.models.user.attributes.name.blank
activerecord.errors.models.user.blank
activerecord.errors.messages.blank
errors.attributes.name.blank
errors.messages.blank
So you could add:
所以你可以添加：
nl:
activerecord:
errors:
models:
user:
attributes:
email:
blank: "foo blank in nl bar baz"
It's documented in the Rails Internationalization (I18n) API Guide, which might give you some more insight.

Just use the Dutch translations file that you can find here. It contains translations for most (if not all) ActiveRecord validation messages.
只需使用您可以在此处找到的荷兰语翻译文件。它包含大多数（如果不是全部）ActiveRecord 验证消息的翻译。
Copy the file to config/locales/in your project.
将文件复制到config/locales/您的项目中。
Alternate method
替代方法
If you want to benefit from updated translations, add the following to your Gemfileinstead of copying the translation files by hand:
如果您想从更新的翻译中受益，请将以下内容添加到您的Gemfile而不是手动复制翻译文件：
gem 'rails-i18n'

The rails I18n guidecovers this pretty well.
该轨道的I18n指南包括这相当不错。
You can put the following in config/locales/nl.ymlto translate the attributes:
您可以输入以下内容config/locales/nl.yml来翻译属性：
nl:
activerecord:
models:
user: "User"
attributes:
email: "Email"
For the error messages, ActiveRecord will look them up in the following namespaces:
对于错误消息，ActiveRecord 将在以下命名空间中查找它们：
activerecord.errors.models.[model_name].attributes.[attribute_name]
activerecord.errors.models.[model_name]
activerecord.errors.messages
errors.attributes.[attribute_name]
errors.messages
model, attributeand valueare interpolated and available in your translations, for example:
model，attribute并value在您的翻译中插入并可用，例如：
nl:
errors:
messages:
blank: "Please fill the %{model}'s %{attribute}"
