Would this not work :
count = i.objects.filter(activities=Activity).count()
Where you would put the count in a for loop for the Activity and iterate
over it.

I'm not sure I understand. Do you want the value of the "count" field in
the Activity model? In that case, you could use values:
activity_counts = i.activities.all().values('id', 'count') #Will give
you something like [{'id': 1, 'count': 3}, {'id': 2, 'count': 5}, ...]

Hi. I don't need a total counter for all related activities. I need a
counter for each related Activity:
Invoice instance:
activity A -> counter: 3
activity B -> counter: 5
...
...
is this possible?
thanks,
Luke

With an Invoice instance, you can easily get the number of related
Activity objects:
i = Invoice.objects.get(pk=1)
num_activities = i.activities.all().count()

Hi everyone. hi have these models:

class Subject(models.Model):
name = models.CharField("Name",max_length=50, blank=True)
...
...
class Activity(models.Model):
label = models.CharField("Act. name",max_length=150)
price = models.DecimalField("price", max_digits=10,
