Suppose I have a queryset qs. For paginating purposes I need to do
something like:
count = qs.count()
qs = qs[0:100]
Unfortunately this executes the query twice, which I don't want.
I can use postgresql windowing function like that:
qs = q.extra(select = {'count': 'COUNT(*) OVER()'})
to get

Well, thanks very much for your effort-y reply. I have read it and it is
useful, though it requires a second reading to recap :)
Well, I thought of a simple solution and it worked: just having a wrapping
function around django login such that it checks whether the use is logged
in or not before

Hi Folks
Following is a description of what i am trying to achieve :
The user should log into a web app, select a file & be able to create a
torrent & a private tracker(http://IP_ADDRESS:PORT/announce) gets created
for that torrent.
I found two libraries mktorrent[1] & py3createtorrent [2],
b
Yes, I did the steps as in the tutorial.
In addition I create one more superuser as described.
Thank you

Sounds like a great idea. I'm going to give it a try. In the meantime,
though...why can I get the script no problem using a non-django, pure

Thanks for user.is_authenticated(), , but Django built in login view
function doesn't call it before executing. So I guess I have to wrap Django
login myself when using it.

Hi all,
I was wondering how can I show the text line numbers in the left of the
text area.
The result is somehow like this:
1 this is first line.
2 this is second line.
;
The number is in the outside of the box, and it is automatically
displayed when the user change the line.

I am trying to use a class based generic view (DetailView) to view user

Hi,
Code looks fine to me, maybe you could give us the exact error message ?
You could also try request.user.id or something to get the actual pk and not
only the user object but that’s just a guess.

Thank you for you reply Tom.
I am now getting:
"Generic detail view home must be called with either an object pk or a
slug."
I have tried using the pk line you pointed to in the get_queryset method.
Should I instead be trying to use def get: ?

Well, I do not totally agree with your point.
The problem with virtual environments such as these is that you have
trouble sometimes figuring out what actually happens behind the scripts
that are used to initialize your environment. Thus comes a natural habit
that I personally developed which is to
Think I now have this working with the following:
def get_queryset(self):

UserModel = get_user_model()

Hmmm. I guess you'll just have to dig deep into your code and make
sure you haven't made any mistakes especially if you are using
conditionals to choose which template to render. Can you mail the link
