Question

I have two models, a Project and an Action:

class Project(models.Model):
    name = models.CharField("Project Name", max_length=200, unique = True)
    complete = models.BooleanField(default=False, verbose_name="Complete?")

class Action(models.Model):
    name = models.CharField("Action Name", max_length=200)
    project = models.ForeignKey(Project, blank=True, null=True, verbose_name="Project")
    notes = models.TextField("Notes", blank=True)
    complete = models.BooleanField(default=False, verbose_name="Complete?")
    status = models.IntegerField("Action Status", choices = STATUS, default=0)

When a Project is marked as complete, I’d like all of it’s Actions to be marked as complete as well.

I’m trying to do this in the Project’s save method:

    def save(self, **kw):
        self.last_modified = datetime.today()
        self.action.all().update(complete=True)

        super(Project, self).save(**kw)

I’m stuck on that third line above. I’m not quite sure how to set all actions connected to this project to complete.

Answer 1

Inside the save method use…

Action.objects.filter(project = self).update(complete=True)
