I'm pretty new to Django still and I know much is still escaping me.
In particular I'm having trouble still with how to query subsets of
related objects.
In this case I have two Models.
class Project(models.Model):
title = models.CharField(max_length=141)
...
class Release(models.Model):
project_fk = models.ForeignKey(Project)
point_estimate = models.IntegerField(choices=ESTIMATE_CHOICES,
null=True, blank=True)
velocity_points = models.IntegerField(choices=VELOCITY_CHOICES,
null=True, blank=True)
...
What I was looking to do is create a way sum the total number of
velocity points in releases related to a Project. I also wanted to
sum the total number of point_estimate points related to a Project.
>From what I see a Custom Manager would seem necessary but I'm getting
confused on related objects and aggregating items. This is for Django
v 1.0 and would not include v1.1 aggregation features.
Thanks in advance for any insight.
