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 <module>
from events.models import Event
File "app\events\models.py", line 12, in <module>
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.
Thanks
