在红宝石上轨我如何重写普通的ActiveRecord的错误信息？ [英] How do I override generic activerecord error messages in ruby-on-rails?
问题描述
在我en.yml翻译文件，我有：
In my en.yml translation file, I have:
activerecord:
errors:
template:
header:
one: "1 error prohibited this {{model}} from being saved"
other: "{{count}} errors prohibited this {{model}} from being saved"
当一个ActiveRecord /验证错误登录到我的应用程序，该错误信息过程中出现：
When an activerecord/validation error occurs during logging into my application, the error message:
1错误被禁止保存该用户的会话
"1 error prohibited this user session from being saved"
时，显示（其中USER_SESSION正在使用的模型）。我宁愿它这样说：
is displayed (where user_session is the model being used). I'd rather have it say something like
错误已经无法登录到您的帐户发生于prevent你。
"An error has occured to prevent you from logging into your account".
我如何重写的一般错误消息，我的具体吗？
How do I override the generic error message with my specific one?
推荐答案
我找到路线的Rails（2.3.8）遵循翻译的错误消息（与国际化0.6.0）： 另外，不要忘记改变full_messages格式，使之与您的自定义消息对应。
I found the routes Rails (2.3.8) follows to translate error messages (with i18n 0.6.0): Also, do not forget to change the full_messages format so that it corresponds with your custom messages.
下面是与模型马，验证属性名（不能为空）的一个例子。
Here's an example with model "Horse", which validates the attribute "name" (cannot be blank).
在你的模型（应用程序/模型/ horse.rb）：
In your model(app/models/horse.rb):
validates_presence_of :name
在你的翻译文件（配置/区域设置/ en.yml）：
In your translation file (config/locales/en.yml):
en:
activerecord:
errors:
models:
horse:
attributes:
name:
blank: "Hey, are you the horse with no name?"
full_messages:
format: "%{message}"
下面是一个链接到回报率，引导页，在这里我发现了这一点。还有其中所需的验证的每一变体的消息的明细表。
Below is a link to the RoR-guides page where I found this. There's also a list of which messages are required for every variant of validation.

- Table with all validations and corresponding messages
的符号和默认设置可能更改与更高版本的Rails和/或国际化的。
The notation and defaults may change with later versions of Rails and/or i18n.
