Description
At present there's no quick way to negate a Q object, so if you need something that .filter()
and .exclude()
can't do, such as Q(A) AND ((NOT Q(B) OR Q(C))
, it's a bit awkward as you have to use QNot(Q(B))
.
Attached patch would allow Q(A) & (~Q(B) | Q(C))
using the bitwise NOT, similar to the bitwise AND and OR already in use.

Moving back to accepted so it doesn't get checked in on trunk. It's already fixed on the queryset-refactor branch.

(In [7477]) Merged the queryset-refactor branch into trunk.
This is a big internal change, but mostly backwards compatible with existing
code. Also adds a couple of new features.
Fixed #245, #1050, #1656, #1801, #2076, #2091, #2150, #2253, #2306, #2400, #2430, #2482, #2496, #2676, #2737, #2874, #2902, #2939, #3037, #3141, #3288, #3440, #3592, #3739, #4088, #4260, #4289, #4306, #4358, #4464, #4510, #4858, #5012, #5020, #5261, #5295, #5321, #5324, #5325, #5555, #5707, #5796, #5817, #5987, #6018, #6074, #6088, #6154, #6177, #6180, #6203, #6658
Interesting idea, Colin. Can you raise this on django-developers?
