Question

I am trying to get one item in a query set but I always get the following error in my view:

Tip matching query does not exist.

Here is my view code:

  tip = None
  if not hole.tip_set.all():
    tip = hole.tip_set.create(content="New")
  else:
    print hole.tip_set.all()
    tip = hole.tip_set.get(pk=1)

When I do print hole.tip_set.all(), the following prints in my console: [<Tip: Tip object>]
But, when I try to “get pk 1”, I get the error Tip matching query does not exist. This doesn’t make sense to me at all. There is clearly an item in the hole’s tip_set. Yet, when I try to retrieve it, it says no tips match the query.

Answer 1

That’s because the object’s PK is not 1.

You’re looking for hole.tip_set.all()[0].
