Long story short: I made tests.py to cover my django code, I modified code and models a lot (18 migrations) and everything was OK.
But after last change and migration (Added some Boolean fileds) my tests start crashing on 8. migration with django.db.utils.OperationalError: no such column: The_new_column
In Apache on web site I can use the new column, add models with it and everything looks nice, but tests fails
Can somebody please tell me, what went wrong and how to correct it?
The long story:
Models.py:
def Ticket_generateUniqueID(related=''):
retval=''
sanitized=''
......
# --- now find unique value
while True:
passNo += 1
retval = generateID()
try:
t = Ticket.objects.get(ticket_number=retval)
pass
except ObjectDoesNotExist:
return retval
....
class Ticket(models.Model):
....
ticket_number = models.CharField(max_length=100,default=Ticket_generateUniqueID,help_text=u"ID of ticket")
ActionRequired = models.BooleanField(default=False,help_text=u"Action Required")
def save(self): # {{{
if not self.id and not self.ticket_number: self.ticket_number=Ticket_generateUniqueID('OTH')
retval=super(Ticket,self).save()
return retval
and my testing session (should start with no test_* database)
$ ./manage.py test -v3
