看来，验证是提高仅仅是添加错误信息到错误堆栈的错误信息。我建议你​​包裹 update_attributes的块在开始/救援/ end`块。

It appears that the validator is raising an error instead of simply adding error messages to the errors stack. I'd recommend wrapping the update_attributes block in abegin/rescue/end` block.

有关更改邮件，你可以采取两种途径：

For changing the message, you can take two routes:

1. 您可以自定义 EnumValidator 使用键从区域文件，使每个条目可能会说的元素％{数}不在列表。您应该能够自定义 activerecord.errors.messages.inclusion 该消息的不在名单部分。对于元素0（导轨）部分中，您既可以硬$ C C语$，作为目前执行（不推荐）或使用的语言环境的文件再次通过添加键说， enum_element ，然后在您的EnumValidator，电话 I18n.translate（：'activerecord.errors.messages.enum_element，数：@count，值：值）。

1. You could customize the EnumValidator to use keys from your locale file so that each entry might say something like the "element %{count} is not in the list". You should be able to customize activerecord.errors.messages.inclusion for the "is not in the list" portion of the message. For the "element 0 (rails)" portion, you could either hard-code the phrase, as is currently implemented (not recommended) or make use of the locale file again by adding a key for say, enum_element, then in your EnumValidator, call I18n.translate(:'activerecord.errors.messages.enum_element', count: @count, value: value).

验证后，检查 errors.keys 为您的枚举列问题。如果您发现错误，删除那些键，并添加自己的消息对于这把钥匙。

After validation, check errors.keys for for issues on your enumerable column. If you find errors, remove those keys and add your own message for that key.

至于你的形式，这听起来像您使用的是动态表单生成器。如果是SimpleForm，你可以尝试指定的确切类型的输入应与为：：选择选项

As for your form, it sounds like you're using a dynamic form builder. If it's SimpleForm, you could try specifying the exact type the input should be with the as: :select option.
