Question

This is my code that fails:

dashboard = Dashboard.objects.get(slug=slug)
users = User.objects.all() # list of users

for editor in dashboard.dashboardeditor_set.iterator:
    users.remove(editor.user)

The error:
‘instancemethod’ object is not iterable

From models.py:

class DashboardEditor(models.Model):
    dashboard = models.ForeignKey(Dashboard)
    user = models.ForeignKey(User)

Can anybody help me figure out how to scrub editors from the list of all users?

Thanks! 🙂

I’d guess from the error message that you are missing parentheses:

 for editor in dashboard.dashboardeditor_set.iterator():

This is because the error message seems to imply that iterator is in instance method so you need to call it to get the actual iterator.
