#11523 closed Bug (wontfix)

ORM/MySQL backend doesn't set pk when Warning exception is raised

Link to the discussion:


from MySQLdb import Warning as Warning
from django.db import models
import unittest

class TestModel(models.Model):
    char_field = models.CharField(max_length=5)

class Case1(unittest.TestCase):
    def test1(self):
        print "Count 1:", TestModel.objects.count()
        m = TestModel(char_field="123456")
        except Warning:
            print "Count 2:", TestModel.objects.count()
            print "",
            print "all()[0].id=", TestModel.objects.all()[0].id

The above code prints:

Count 1: 0
Count 2: 1 None
all()[0].id= 1 
  • which means to me that although m is saved to db, primary key is not set in after

If you look into newsgroups thread above, it seems that MySQLdb returns pk properly.

As of #23871, Django no longer promotes warnings to exceptions, so I think this issue is obsolete.
