ipaddress

[Jisson Varghese]

Hi all,

First am sorry ,its a python specific question not django based.
 I am developing a mobile application, using  python in server side. I want
to get user's ipaddress(Now user's request not sending ipaddress as a
parameter to my server). I am using cherrypy server , Now I take IPaddress
using following code,
   ipaddress = cherrypy.request.remote.ip
  I have a doubt whether this generate an ipaddress in the form
xx.0.0.0/32
( a private range ).?
Thanks

RE: Determine gender from first name

[walter capio]

All depends on how many users you have and how accurate you want your data to 
be. If your language uses specific morphemes for women (usually non-european 
languages have marked feminine morphemes; male names and pronouns are not 
marked), then you could write a parser for these names. Yet I doubt your data 
will be any better than 90% accurate. Don't forget people construct virtual 
identities and often use loanwords. You could also parse their content (blogs, 
comments,... *is this legal?) and see which first person pronouns, verbs, etc. 
they use. If the latter are explicit feminine forms, use a feminine welcome.
So, I would just work around the gender-specific welcome. Replace it somehow. 
Convince your client it is somehow spooky to directly address the visitor.
Or, even better, add a gender category to your db and register form and 
convince your client that some day it will prove interesting for data mining 
purposes.
greetings,djinja

Thanks for the additional thought on this.  It is a much appreciated

logistics of what I had conceived, and by this morning I had pretty

If the data is presented as table, datatables is a really nice jquery

 I'm presuming the initial data set being sent is the "full" list. If
so, might it not be useful to somehow (Caveat: I'm /not/ skilled at

 Granted, adding another language on top of Python, Django, and the

saving in a view

[MikeKJ]

I have 2 models Count is purely an incremental counter a model called Sale,
the reason for the Count models is to increment a reference for Sale and
other models

In a view I get the latest sale and count then I want to save the incemented
count (number) to Count also save number to Sale

customer =
Sale.objects.all().order_by('-id').filter(email_address=email).distinct()0
this = Count.objects.all().order_by('-id')0
number = this.number + 1
a = this.save(force_insert=True)
ref = number
reference = number
name = customer.name
salutation = customer.salutation
b = customer.save(force_update=True)

I know the field names are rubbish but can anyone spot where I am going
wrong please

First off, the instances of "0" at the end of the first two lines should be
[0] (surrounded by square brackets), but I'm assuming that that's an
artifact of the email transport.

Past that, your code doesn't actually *do* anything, other than pull two
objects out of the database, and save them again, unmodified. Let's look at
the method you've pasted, line by line:

customer
> = Sale.objects.all().order_by('-id').filter(email_address=email).distinct()[0]
> this = Count.objects.all().order_by('-id')[0]


This part retrieves two objects from the database. You may want to guard
these two lines with an exception handler -- if there are no matching Sale
objects, or if the Count table is empty, either of these lines could raise
a KeyError.

number = this.number + 1


This line creates a new local variable called number, and assigns it the
value of this.number + 1. It doesn't do anything to the 'this' object at
all.

a = this.save(force_insert=True)


So this line forces 'this' to be re-saved (remember, though, that it hasn't
been modified, so the save doesn't really do anything). Model.save()
doesn't return anything, so 'a' is assigned the value None.

ref = number
> reference = number
> name = customer.name
> salutation = customer.salutation


Again, these just create some new local variables, but they don't actually
change your customer object at all, so this line:

b = customer.save(force_update=True)


Just forces a re-save of the unmodified customer object.

I"m not sure exactly what it is that you're trying to do with this view,
but I think that you are going to need some lines that actually update the
'this' and 'customer' object. You would do that like this:

this.number = this.number + 1

or
customer.reference = number

Then, when you save the objects (and just use "customer.save()", the
force_update=True isn't really necessary), then the new values you have
assigned will be saved in the database.

Re: /?next= not redirect user

[snow leung]

first:
use 
in your html template.

second:
you can do it in your login method:
def login(request):
if reqeust.GET:
#do something u want.
return render_to_response('your html template',
{next_url:request.GET.get('next',None)})
if request.POST:
if login():#do login
  next_url = request.POST.get('next',None)
  if next_url:
return HttpResponseRedirect('next_url')
  else:
return HttpResponseRedirect('where u want')
