Playing with the idea of a queryset which cannot be accidentally Evaluated, only cloned.
class UnevaluableQuerySet(QuerySet):
def __init__(self, *a, **kw):
super(UnevaluableQuerySet, self).__init__(*a, **kw)
self._frozen = False
def freeze(self):
clone = self._clone()
clone._frozen = True
return clone

django-filters .. paring down the choices in a related widget.
from django_filters import FilterSet
class MyModelFilterSet(FilterSet):
class Meta:
model = MyModel
fields = ['my_relation'] # internally this is a reverse relation, so MyModelInstance.my_relation_set.all()
# How do I get it so that the ModelChoiceFilter (actually a ModelMultipleChoiceFilter!) is only
# those items which exist given the FilterSet's original queryset (self.queryset.all())

File handling

Probably want to be able to read from STDIN or a file ...

File names, without extension.

All files should be checked for extension equivalents, and for lowercase or alternative-case variants.

Maybe approximate doing order_by("thing", "-otherthing", "thing2") in Django, but for python things. Originally piqued my interest because of bmispelon on #django IRC
