How to add error message when `UNIQUE constraint failed`

[wgf4242]

when import twice get a long Traceback (most recent call last):

class Employee(models.Model):
  id_number = models.CharField(max_length=180, null=True, blank=True, unique=True)

I want to show the error like admin default error message, like already exist Employee with this _id_number

When add same id_number trigger UNIQUE constraint .

Django admin give a friendly error message when id number is not unique.

django-import-export give a Exception Traceback .

I want django-import-export give a friendly error message, how to do this?
