Is there a specific reason Djangos QuerySet does not implement
__contains__? It doesn't seem very complicated to me, but maybe I'm missing
something.
When checking if an object is in e queryset I always use code lite this:
if queryset.filter(pk=obj.pk).exists():
The pythonic way would be:
if ob
Hello Johan,
You explained the upside. There's one downside to be aware of. If you already
fetched the queryset, `if obj in queryset` will make a new database query,
which will be slower than walking through the already fetched data (unless the
queryset is really large and the database really c

I don't see why we couldn't implement __contains__ to do a walk through
_result_cache if it has been fetched?

It may help to know that QuerySet.__contains__() was implemented until
Django 1.6 when chunked reads were removed from QuerySet iteration:

My 2 cents, I think @johan's suggestion makes sense.

It's very pythonic. it should do what __len__ does and cache it, if you
want the single quick db query you can always use exists().

Hi folks,
I recently ran into an issue around the SESSION_COOKIE_DOMAIN and
CSRF_COOKIE_DOMAIN settings that seems like it could be fixable by adding
some extensibility.
Before submitting a patch/PR, I wanted to get the community's opinion on
whether this is worth addressing in the framework,

You can already achieve what you're aiming to do in an outer middleware by
mutating the cookie in response.cookies. The cookie object can have its
domain changed before it is sent to the client:

>>> resp = HttpResponse()
>>> resp.set_cookie('foo', 'bar', do

The answer is "yes", but this question was asked on a wrong mailing list.

Uh, sorry, I haven't noticed that the question was "how", dummy me. There
are several ways to do this, as I wrote consider asking on proper mailing
