flatpages and views on home page

[Bobby Roberts]

hi group.

Got an issue I need some help with asap.  I have flatpages installed
and a url at / for my home page.

I've also got a form on my home page powered by a view.

my urls portion for this view is:

rr'^$','DoNewsLetter'),


my issue is this... the view executes perfectly, but the flatpage
doesn't execute.  Is there anyway to get the flatpage to show AND the
view to execute successfully?

Re: Integrating User Profile with Auth

[darren]

I think that my main problem was that I was expecting the save to the model
form to actually create the profile.

Here's what I ended up with in my view.

 86 @login_required
 87 def createProfile(request):
 88 UserProfile.objects.get_or_create(user=request.user)[0]
 89 if request.method == 'POST':
 90 form = UserProfileForm(request.POST,
instance=request.user.get_profile())
 91 if form.is_valid():
 92 form.save()
 93 return HttpResponseRedirect("/")
 94 else:
 95 return render_to_response('fav/createProfile.tpl', { 'form'
: form  }, RequestContext(request) )
 96 else:
 97 form = UserProfileForm(instance=request.user.get_profile())
 98 return render_to_response('fav/createProfile.tpl', { 'form' : form
}, RequestContext(request))

get object qs with generic relation

[Andrew Marder]

Dear Django users,

I have a tagging system that uses a GenericForeignKey to assign tags
to generic objects. I would like to write a function that given a
model and a list of tags returns a QuerySet containing all instances
of that model that have been given those tags.

I'm not a huge fan of django-tagging's solution
(get_intersection_by_model):
http://code.google.com/p/django-tagging/source/browse/trunk/tagging/models.py

Any elegant solutions out there?

Thanks for the help, Andrew

Re: Facebook Comments

[Sævar Öfjörð]

Where exactly are you expecting them to be posted?
I think the Facebook Comments plugin is only supposed to provide a
comment feature on individual pages so that you don't have to write
your own, it's not an external comment box for your FB page.

Re: Staticstic app, ask for idea.

[Lucian Romi]

Thanks for your help. It's very clear.
I used measure_list method but it thrown and exception.
Here's how I did,
In my app's ModelAdmin I override changelist_view method.
I was able to get the queryset, then instantied cube with this queryset.
If I didn't call measure_list, everything works fine. But if I call
it, there is exception, but django didn't give much useful infomation
in stdout, and I'm going to debug it later.
If you aware of anything I'm doing wrong, please let me know. Or is
there any sample I can quickly run just to verify there is nothing
wrong with my enviroment.
Thanks.

Sorting related model

[Brad Buran]

Given the following two models forming the base of a wiki-style app:

class Page(models.Model):
current_revision = models.IntegerField()

class PageContent(models.Model):
page = models.ForeignKey(Page)
revision = models.IntegerField()
created = models.DateTimeField()

Here, we have a canonical Page object with a current_revision that always
points to the most current revision, stored in PageContent.  How can I
construct a Page queryset, ordered by the Pages that have the most
recently-created PageContent?

Currently, what I am doing is:

qs =
PageContent.objects.filter(revision=F('page__current_revision')).order_by('created').select_related()
pages = [content.page for content in qs]

This works fine, but is there a more straightforward way to do this?

Thanks,
Brad

It looks like there is no svn tag for 1.2.3:

http://code.djangoproject.com/svn/django/tags/releases/

which affects those of us who use pip requirements files for version
maintenance.

Overriding individual models in an app without forking

[Eric Man]

Oops my previous post got hard-wrapped by safari's textarea. :( Here  
it is again. (I'm assuming moderator is going to prevent me from  
double posting).


---

I was reading about how django's apps' models can't be easily  
overridden. - e.g http://www.scribd.com/doc/37113340/Why-Django-Sucks-and-How-we-Can-Fix-it


So I was looking at this new app I was making, a CMS for online shops,  
and thought of a way for users of my app to override individual models  
in my app without forking.


I want to ask, how does it look? Would it be "bad practice"? How else  
could I enable user to override individual models?


It uses django-nonrel version of django so the code might be a bit  
weird to some. I think it works the same for normal django, though.


abstract.py - "Normal Model Code"
http://pastebin.com/C9FFJJK8

This file has a bunch of the models I would have had anyway if I  
didn't enable model overriding. i.e 'Setting', 'Country', 'Product',
'UserProfile', 'Category', 'Promotion', 'Cart', 'PaymentMethod',  
'Order' and 'Item'


models.py - "The 'Magic' Code"
http://pastebin.com/ezhPA6uJ
This file contains an "override_models" method. Use it like  
"override_models(Country=MyCountry)" whereever... e.g in your  
models.py, where MyCountry is has a strict is-a relationship with the  
Country model in abstract.py, meaning they must have at least all the  
fields and all the relationships of the original model, though more  
can be added.


It also contains some lazy many to many links. I used appengine so I  
couldn't use django's many_to_many.


management.py - "Example Usage Code"
http://pastebin.com/jK3vzMt7
(I was just using management.py to do random testing... )

Note my new custom model have new fields... "parent" and "test".

I don't really know any advantages of overriding individual models in  
a module this way besides being able to make the models have  
additional fields so you don't have to do something like define a  
UserProfile model to add extra features to User, though.

Django document said the QueryDict is only immutable, but why I can edit it sometimes

[ouds...@gmail.com]

Django document said the QueryDict is only immutable, but why I can
edit it sometimes

The codes is almost the same, for example following,

The first kind of condition, the item I want to edit is not a field of
form.

I add a Captcha when user register or login, the querydict is mutable
when registering

if request.method == 'POST':
data = request.POST
data['captcha_text'] = Captcha(request).get()

But the same code when do login, the querydict is immutable, it is
must be create a copy

if request.method == "POST":
data = request.POST.copy()
data['captcha_text'] = Captcha(request).get()

The second kind of condition, the item I want to edit is a field of
form, but in fact I think it has no relation with form.

user = request.user
if request.method == "POST":
data = request.POST
data['title'] = data['title'].strip()
now = datetime.datetime.now()
topic = Topic(id = _md5_key(now, user.username), profile =
user.get_profile(), \

It is ok, but when I do this in other view, then django tell me the
querydict is immutable.

if request.method == 'POST':
data = request.POST
print data, '\n\n'
data['name'] = data['name'].strip()
print data, '\n\n'

What's difference ?

Thanks

Re: Staticstic app, ask for idea.

[sebastien piquemal]

class MyModelCube(Cube):
my_dimension = Dimension(field='my_float_field__range',
sample_space=[(0, 1.5), (1.5, 6.2)])

@static
def aggregation(queryset):
return queryset.count()/MyModel.objects.count() * 100

Basically when you declare a dimension, you can use any field-lookup
from Django, so when I write 'my_float_field__range' it means :
-> You said in your question "There is a float field in my
model(table)", as you didn't tell the name of your "float field", I
wrote : 'my_float_field'
-> You said that you want the percentage in each range... so I used
the field look-up '__range' from Django.

If your "float field" is called "gnagna", then you would declare your
dimension like this : Dimension(field="gnagna__range", ...


Ok ... when you have declared this, you have a Cube class. After, you
need to instantiate an object from this class, in order to use its
methods ! To do this, you call the Cube constructor, with a queryset
as argument :
>>> instantiated_cube = MyModelCube(a_queryset)

Then, and only then, you can use the methods (all the calculations
will be based on "a_queryset"). For exemple, if you want a list of
measures :
>>> my_measures = instantiated_cube.measure_list("my_dimension")

Considering the sample space I used to declare the dimension, this
should give something like this :
>>> my_measures
[65, 29]
Where 65 means "65% of the floats are in the range [0, 1.5]", 29 means
"29% of the floats are in the range [1.5, 6.2]"

Is it clearer like this ?

paypal ipn change

[Tim Arnold]

Hi,
I started having trouble with paypal IPN on Sept. 4 (a week ago), but
didn't know it until they notified me yesterday that my endpoint url
was failing. Well, I had just upgraded to Django 1.2.1 and figured it
had to be that or some code refactoring I had done.

However, as far as I can tell, the problems were due to a change in
paypal's mechanism. What I did was change my endpoint to accept data
from either a POST or a GET. Previously it only accepted POST data.
When I made that change the IPN started coming through again.  Just
for completeness, here's my endpoint code. Note that yes, I'm not
doing anything special with the data now, just writing it to a file so
I can see the last transaction's data:

@csrf_exempt
def endpoint(request):
def verify(data):
newparams={}
for key in data.keys():
newparams[key]=data[key]

newparams["cmd"]="_notify-validate"
params=urllib.urlencode(newparams)
req = urllib2.Request(verify_url)
req.add_header("Content-type", "application/x-www-form-
urlencoded")
fo = urllib2.urlopen(verify_url, params)
return fo.read()

def process(data):
f = open('/home/myuser/mydata.txt','wb')
f.write('%r valid' % data)
f.close()
return HttpResponse('Ok')

def process_invalid(data):
f = open('/home/myuser/myerrors.txt','wb')
f.write('%r error' % data)
f.close()
return HttpResponse('NOT Ok')

default_response_text = 'Nothing to see here'
verify_url = "https://www.paypal.com/cgi-bin/webscr;
if request.method == 'POST':
data = request.POST
elif request.method == 'GET':
data = request.GET
if verify(data):
process(data)
else:
process_invalid(data)
return HttpResponse(default_response_text)

Why don't you just read the code snippet I posted ?

For the record:

* modules are objects
* functions, classes and anything else defined in a module are
attributes of the module
* "getattr(obj, "attrib")" is the exact equivalent of "obj.attrib"

also and FWIW, you never import functions (or anything else) directly.
The

  from module import name

syntax is syntactic sugar for:

  import module
  name  = module.name
  del module

I have to echo Bill's advice here. Use the Python logger generously in
your IPN view handling code. Paypal has a habit of subtly changing
their API or their POST parameters periodically. Anyway, unless you
are getting hundreds of IPN's a day, I'd log all kinds of stuff to a
file and study it to see where it is going wrong. Good luck,
