IntegrityError: Field "may not be NULL" even though blank=True

[Tyson Tate <tyson@…>]

Despite adding "blank=True" to my fields, I am unable to save them through the admin interface. I get errors like the following:

Exception Type: IntegrityError at /admin/events/event/add/
Exception Value: events_event.start_time may not be NULL

With the following model:

class Foo(models.Model):
	the_char = models.CharField(blank=True, maxlength=100)
	the_text = models.TextField(blank=True)
	the_integer = models.IntegerField(blank=True)
	
	the_time = models.TimeField(blank=True)
	the_date = models.DateField(blank=True)
	the_datetime = models.DateTimeField(blank=True)
	
	class Admin:
		pass
	
	def __str__(self):
		return "Foo"

The following fields, if left blank, give me the above error:

the_integer
the_time
the_date
the_datetime

the_char does not behave unexpectedly (e.g. it allows blank values without throwing an error).

I forgot to add that the_text does not behave unexpectedly, either.

Use the null option as well.

You are seeing documented behavior, see the descriptions of the null (​http://www.djangoproject.com/documentation/model-api/#null) and blank field options (​http://www.djangoproject.com/documentation/model-api/#blank) for more details.

Fixed #6189 -- Modified test that need Internet access so they use a mock instead. Thanks Gregor Müellegger for the patch.

Sorry for the noise. I mis typed the ticket number in a commit message.
