I'd stick to setattr and maybe verify that the key in the dictionary

I'd probably be a bit more cautious, since get_all_field_names gets
foreign keys and all sorts and the field might not be in the
dictionary.
I'd suggest:
# Make a frozenset of the fields for fast access:
allowed_fields = frozenset(obj._meta.get_all_field_names())
for field, value in dictionary_o
