我有一个包含大量字段和模型验证的表单。
如何返回所有可能引发的验证错误？
我需要它来为所有这些语言编写语言环境。
我想要一个这样的列表：
password blank
password too_short
password confirmation
login blank
login invalid
email blank
email too_short
email invalid
等

标签： ruby-on-rails ruby validation forms
最新的 Rails 翻译位于：rails-i18n。
ActiveRecord 错误在每个 .yaml 中的 lang:errors 和 lang:active_record 下。
同样在你的应用程序中 config/locales/en.yml 是默认的。

validate，但不会收到所有错误（不会引发无效或确认错误）。而且我不想使用全局语言环境，因为我想为每个错误为许多模型设置单独的错误
基本上是 Pablo 所说的，只是 rails 文档上的页面没有显示如何覆盖特定模型和字段的消息。这是我的一个应用程序中的一个示例：
activerecord:
errors:
full_messages:
format: "{{message}}"
#define standard error messages, which we can overide on per model/per attribute basis further down
messages:
inclusion: "{{attribute}} is not included in the list"
exclusion: "{{attribute}} is reserved"
invalid: "{{attribute}} is invalid"
confirmation: "{{attribute}} doesn't match confirmation"
accepted: "{{attribute}} must be accepted"
empty: "{{attribute}} can't be empty"
blank: "{{attribute}} can't be blank"
too_long: "{{attribute}} is too long (maximum is {{count}} characters)"
too_short: "{{attribute}} is too short (minimum is {{count}} characters)"
wrong_length: "{{attribute}} is the wrong length (should be {{count}} characters)"
taken: "{{attribute}} has already been taken"
not_a_number: "{{attribute}} is not a number"
greater_than: "{{attribute}} must be greater than {{count}}"
greater_than_or_equal_to: "{{attribute}} must be greater than or equal to {{count}}"
equal_to: "{{attribute}} must be equal to {{count}}"
less_than: "{{attribute}} must be less than {{count}}"
less_than_or_equal_to: "{{attribute}} must be less than or equal to {{count}}"
odd: "{{attribute}} must be odd"
even: "{{attribute}} must be even"
record_invalid: "Validation failed: {{errors}}"
models:
quiz:
blank: "{{attribute}} can not be blank"
user_session:
blank: "{{attribute}} can not be blank"
attributes:
login:
invalid: "Please enter your user name"
password:
invalid: "Please note that passwords are case sensitive"
我还更改了错误消息的基本格式，因为有时我不希望将字段名称放在消息的开头。所以，我改变了
errors:
format: "{{attribute}} {{message}}"
到
errors:
format: "{{message}}"
这就是为什么我在随后的错误中指定{{attribute}}，以便在大多数但不是所有情况下将其放回原处。
还要注意，我使用的是 {{var}} 的旧语法，而不是 %{var}。但同样的原则也适用。
