You could move the Event import to the run_job method which is the only place where your code needs it: file : app/jobs/models.py -- class Job(models.Model): ... def run_job(self): from events.models import Event result = do_something() e = Event(timestamp_gmt=datetime.now(), job=self, result=result) self.save() return result -RD --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

One solution to this is described in the relevant documentation: http://docs.djangoproject.com/en/dev/ref/models/fields/#foreignkey -- Ramiro Morales http://rmorales.net PyCon 2009 Argentina - Vie 4 y Sab 5 Septiembre Buenos Aires, Argentina http://ar.pycon.org/2009/about/ --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

NameError: name 'Job' is not defined
Hi, I'm new in django and I have problem with importing models I have two class : Job and Event The Job class defines a method run_job() wich do something and log the result by creating a new Event so I need to import the Event class from file app/events/models.py The Event class reference the job who created the log entry so I need to import the Job class from file app/jobs/models.py file : app/jobs/models.py -- from events.models import Event ... class Job(models.Model): ... def run_job(self): result = do_something() e = Event(timestamp_gmt=datetime.now(), job=self, result=result) self.save() return result file : app/events/models.py -- from jobs.models import Job ... class Event(models.Model): ... timestamp_gmt = models.DateTimeField(null=False, editable=False) job = models.ForeignKey(Job, blank=False, null=False) When I start the serveur I have the following error : ... File "app\jobs\models.py", line 8, in from events.models import Event File "app\events\models.py", line 12, in class Event(models.Model): File "app\events\models.py", line 14, in Event job = models.ForeignKey(Job, blank=False, null=False) NameError: name 'Job' is not defined It's like Django doesn't like the cross import between Job and Event. Anyone can tell me what I'm doing wrong ? I think the easy solution is to declar the Event class in the Job model file but I'd like to keep them in different files.
