details hash sets :error to the message instead of the validator type

[Neil Souza]

When i do

validates :post_code, zipcode: true

the record.errors[:post_code] object looks like

#<ActiveModel::Errors:0x000000057dec18 @base=#< ... post_code: "bad!", ...>, @messages={:post_code=>["Invalid ZIP / postal code"]}, @details={:post_code=>[{:error=>"Invalid ZIP / postal code"}]}>

where record.errors[:post_code].details[0] is {:error=>"Invalid ZIP / postal code"} instead of the Rails standard behvior of the "validator type" symbol (which would be :invalid_zipcode in your case) (example).

This prevents translating the error into anything other than the default locale:

# config/locales/zh-CN.yml
zh-CN:
  errors:
    messages:
      invalid_zipcode: 无效邮编号码

I18n.t "errors.messages.#{ record.errors.details[:post_code].first[:error] }", locale: 'zh-CN'
=> "translation missing: zh-CN.errors.messages.Invalid ZIP / postal code"

It's expected to produce a translation as it does with built-in validations:

I18n.t "errors.messages.#{ record.errors.details[:name].first[:error] }", locale: 'zh-CN'
=> "不能为空字符"

Is there any reason the library is using the string message instead of the "validator type" symbol?
