#1312 closed enhancement (fixed)

QuerySet.in_bulk demands list, should demand iterable

Description

The QuerySet.in_bulk method currently uses the following to ensure it has been passed a list of IDs:

def in_bulk(self, id_list):
    assert isinstance(id_list, list), "in_bulk() must be provided with a list of IDs."
    assert id_list != [], "in_bulk() cannot be passed an empty ID list."
    ...

This means you can't pass in some other iterable that returns ids, which is a bit of a shame. Suggest doing this instead:

def in_bulk(self, id_list):
    try:
        iter(id_list)
    except TypeError:
        assert False, "in_bulk() must be provided with a list of IDs."
    id_list = list(id_list)
    assert id_list != [], "in_bulk() cannot be passed an empty ID list."
    ...

Resolution: → fixed
Status: new → closed

(In [2221]) magic-removal: Fixed #1312 -- made QuerySet.in_bulk() accepting of any iterable, not just lists
