What steps will reproduce the problem? 1.

create a model with unique constraint.

class Test(models.Model): name = models.CharField(max_length=100) class Meta: unique = 'name'

2.

insert two row with same name, try to ignore IntegrityError

from django.db import IntegrityError try: Test(name='test').save() Test(name='test').save() except IntegrityError, e: pass

What is the expected output? What do you see instead?

It should not raise IntegrityError since we ignored it, but it still raise IntegrityError, because pyodbc.IntegrityError is not the same exception as django.db.utils.IntegrityError.

What version of the product are you using? On what operating system?

Please provide any additional information below.

Apologize for my poor english.
