I18n 中的字符串插值用于活动记录验证错误

Question

我有一个非用户友好的验证错误消息，我想覆盖它：

Cannot delete record because dependent [unfriendly model names] exist

协会在哪里

has_many :unfriendly_model_names, dependent: :restrict_with_error

我希望它是

Cannot delete record because dependent [nice readable model names] exist

我希望我可以使用 I18n，但是我如何以及在什么时候将更友好的字符串传递给record插值？

en-GB:
  activerecord:
    errors:
      messages:
        restrict_dependent_destroy:
          has_many: "Cannot delete record because dependent %{record} exist"

Answer 1

您必须本地化关联属性。因此，如果您试图销毁一个user有许多posts限制的错误：

en:
  activerecord:
    attributes:
      user:
        posts: "nice readable model names"
