Rails：验证唯一性时显示重复

Question

我有一个Rails模型，可以验证它的slug是唯一的，就像这样：

validates_uniqueness_of :slug

我在批量导入过程中遇到了很多验证失败，并出现如下错误：

ERROR: invalid () - Validation failed: Slug has already been taken
ERROR: invalid () - Validation failed: Slug has already been taken
ERROR: invalid () - Validation failed: Slug has already been taken
...

我想让错误消息显示哪些slugs验证失败。怎么办呢？

Answer 1

validates :slug, uniqueness: { message: "%{value} has already been taken" }

如果这是在日志中，我认为您将编写自定义验证并将其记录在那里。
