Re: incrementing non primary keys.

[Hutch]

Yes, the integer is needed, it's part of the spec. It's used for job
numbering. the problem being, they need not only an integer, but each
tenant needs sequential numbers.

if it was up to me, I would just remove it.

Re: Confused about thread locals... again.

[ringemup]

I faced this problem, and ran into the issue that the request object
is not passed to the template loader, so there's no way to get your
domain from within a custom template loader without using
threadlocals.

What I did instead was as follows:

1) Write a custom render-to-response type function that selects the
template using select_template based on the theme for the domain
2) Write a custom template tag that will select the correct template
for an include based on the theme, and use it instead of the standard
{% include %} tag
3) Write a custom context processor that will determine the base
template for the theme, and pass it in a base_template variable for
use in {% extends base_template %}

Note that (1) means that you will not be able to use generic views
(well, at least pre-class-based ones) or views from third-party apps.
However, depending on your theming system, you may be able to get away
with just (3) or a combination of (2) and (3).

Re: Getting 'specified module cannot be found' error when synching model to DB

[W. Craig Trader]

It sounds like you have a Windows and/or Python path problem.  The DLL
that's being loaded (kernel32.dll?) isn't on the Windows path (or in the
Python lib directory) when Python is attempting to load it.  Certainly
nothing to do with Django.  What version of Python are you using?

Re: Confused about thread locals... again.

[W. Craig Trader]

I think that the correct solution for your problem would be, instead of
hacking around with the template path on the fly like this, to instead write
a template loader for your application, and apply the logic you need within
the template loader itself.

See:
http://docs.djangoproject.com/en/dev/ref/templates/api/#loading-templatesand
http://code.djangoproject.com/browser/django/trunk/django/template/loader.pyfor

I gave up on the form validation and went through to analyzing the input via
the raw unicode in request.POST itself.

PostgreSQL also has a very good built-in full text search function.  You'll 
need to write a tiny bit of raw SQL, but you can use it with the new .raw() 
query sets.

You're trying to do what's called full text search (FTS), and
databases out of the box are horrible at doing that (i.e. without the
FTS components). You'll run into all kinds of issues trying to
construct the query, and the performance will be bad.

If you're using MySQL, Django can interface with its FTS component -
http://docs.djangoproject.com/en/dev/ref/models/querysets/#search

Otherwise, I suggest using one of the open source search engines
(Solr, Whoosh, Xapian etc.) and using Haystack to connect it to
Django. Whoosh is a nice, easy choice and works for sites with small
amounts of traffic.

Re: Django-Facebook (yet another thread)

Facebook published a sample GAE application. The code is pretty
straightforward and you can pretty much use the same concepts in your
Django code. I would think that the signed request logic would work
best in middleware.

Re: virtualenv and deployment

[W. Craig Trader]

Alex ...

You're not going to be able to trick your host into loading mod_wsgi from an
.htaccess file -- Apache doesn't allow the load directives in .htaccess
files.

While mod_python is not supported, and it has a large number of open issues,
there aren't any specific security holes you really need to worry about; I'm
using mod_python on a project at work because mod_wsgi isn't supported in
our deployment environment.  I wouldn't recommend mod_python as the
direction for all future work, but it will get the job done until you can
get mod_wsgi deployed with your host (or move to another host).

See my earlier post from today (look for Re: running projects on the back of
a base URL and having issues with the homepage) for more details about
making mod_wsgi work with VirtualEnv.  The apache script for mod_python is
similar to the one I posted earlier ; the only differences involve making
certain that you chdir to your project directory, and that you import the
Django mod_python handler.

The mod_python configuration is significantly different from the mod_wsgi
configuration, and look like this:


  SetHandler python-program
  PythonPath "[ '/data/web/foo/apache', ] + sys.path"
  PythonHandler django_mp
  PythonInterpreter foo


  Alias /static/ /data/web/foo/site/foo/static/
  
SetHandler None
  

In this case, mp_python represents /data/web/foo/apache/mp_python.py, which
is my script to deal with configuring the VirtualEnv environment and then
starting the Django mod_python handler.  It's basically an amalgam of the
VirtualEnv activate_this.py script, and the mod_python startup script from
the Django documentation.

Confused about thread locals... again.

[Doug Ballance]

First, I'd like to find out if there is a better way than thread
locals to do what I want to do.  From what I can tell, it isn't
possible any other way.   Finally, I don't understand why my thread
locals implementation/hack works - which scares me, so I would like to
ask the wiser gurus out there for an explanation.

Need: To alter the template path used by a custom template loader
based on the the request object.  Specifically I want to alter it
based on the incoming domain, and sanitized cookie value allowing
'theme' selection.

I have a basic theme setup using thread locals that works.

in the same module/directory I have:

base.py -> contains the theme objects, thread locals variable, and a
couple of get/set functions that just use getattr/setattr to set a
theme attribute on the local() instance.

middleware.py -> contains the middleware that calls my "set theme"
function

loader.py-> contains the template loader which calls my "get theme"
function

The base setup works fine, but was written with the intention of
subclassing it for another app to set the theme according to a 'site'
object that gets created by another middleware (we serve multiple
sites from one fastcgi instance).  So I have another middleware.py
file in another app that imports my ThemeMiddleware and subclasses it
overriding the method returns the template path to cause the loader to
look for that sites templates.

This does not work.  I get two different thread locals instances
(print shows different addresses), despite all manipulation of the
local variable happening in base.py just as it did in the working
version.

I've had issues in the past with thread locals working differently
depending on module import method.  So I stripped out the thread
locals bit from base.py and put in all by itself in thread_locals.py:

---
try:
from threading import local
except ImportError:
from django.utils._threading_local import local
thread_local=local()


Now in base.py I added 'from thread_locals import thread_local' at the
top of the module, and nothing else changes.  I was hoping that the
same import statment (it's only imported once, in one file) would
bypass the problem, but it doesn't.

Next I moved the thread_locals.py file from the same directory as my
other theme files to the project root, in the same location as
django's settings.py.  No other changes were made.

It works.

I should be happy, but I'm not comfortable allowing solutions I don't
reasonably understand to go into production.  I'd love to drop thread
locals entirely, but short of that some understanding of what is
happening and why would be a big help.  I googled the heck out if it,
but didn't find anything that fit.

Thanks!

I am somewhat unclear about my membership status with the Django users
group.  I subscribed through Google Groups, and posted a message about two
hours ago.  I also received an email record of my post.  However, I don't
see my post listed yet; furthermore, when I go directly to the Django user
group page, it says I can't post because I'm not yet a member.  Can anybody
clarify?

Re: __init__.py file executed twice ?

Yes it seems usual referring to the blog post. So if the serveur
restart, that's not a problem that the init are executed several times...

With the mod_wsgi and apache where can I see the results of my "print" ?

Don't need this SetHandler directive. That was need for mod_python but not 
with mod_wsgi.

to here, should be able to be simplified to:

  activate = os.path.join(here, 'bin', 'activate_this.py')
  execfile(activate, dict(__file__=activate))

  sys.path.insert(0, os.path.join(here, 'site'))

I no longer object to the activate_this.py script even though it modifies 
sys.prefix. Although technically that could be problematic, hasn't shown 
itself to be in practice.

Re: virtualenv and deployment

[Álex González]

Hi guys!

Thanks for your replies!

My hosting is a shared hosting and I think that I can only uses mod_python
at the moment. I can load mod_wsgi from htaccess (I test it) but I can edit
my virtualhosts or something similar... any trick to get mod_wsgi
up?

About the virtualenv as Piotr said, some modules must be compiled, so my
solution was create a requeriments files as he said, but include in my code
django-registration and django-piston because the versions installed with
pip doesn't work for me (it said me that it's the correct version, but I can
get a actual version at bitbucket).

Now my question is, mod_python is deprecated but it's dangerous to use it
for a months (until I get money to migrate the code to a non-shared
hosting?). And the old question: can I trick the hosting to use mod_wsgi if
I can load it from htaccess?

Thanks!

Logging Handler AdminEmailHandler not working

[Adrián Ribao]

I get an error when using AdminEmailHandler.

The error message is: __init__() takes at least 5 non-keyword
arguments (2 given)

is in django/django/utils/log.py in emit line 90:

reporter = ExceptionReporter(request, is_email=True, *exc_info)

where exc_info = ()

Is it a bug or I'm missing something?

Getting 'specified module cannot be found' error when synching model to DB

[Charlie]

I've set up a PostgreSQL/PostGIS spatial database, and created
settings and model files for a new project.  When I try to synch the
model with the DB, I get the following error message (last lines
only):

  File "c:\Python26\lib\ctypes\__init__.py", line 355, in __init__
self._handle = _dlopen(self._name, mode)
WindowsError: [Error 126] The specified module could not be found

I ran a print statement in the __init__py file and found that the
module they're referring to is kernel32.  Can anyone provide any
insight into this?

Thanks in advance.

Re: virtualenv and deployment

[W. Craig Trader]

Alex ...

In order to do a simple copy you'll need to make sure that:

   1. You're using the exact same version of Python on the host as you use
   to develop.
   2. Python is installed in exactly the same locations (host and local).
   3. Your environment is located in the same locations (host and local).

If not, you're going to need to experiment with virtualenv --relocatable to
see if it meets your needs.  (I'm doing this for my application, but it
isn't perfect, and doesn't work well with Windows.)

Failing that, you may need to create a new virtual environment on the host,
and then install your packages using pip, before copying your application
files.  (pip freeze and pip bundle can be your friends here.)

A browser of tags (very difficult... unless for me)

[marcoarreguin]

Hi, I have a big problem, I'm doing a browser, but I'm using a lot of
things kind itertools and pyparsing and combinations like nCm to
combine tags and make a lot of search.

I think the problem is about combining querysets to show one result.

I'll show you the algorithm, this is my view, and as you can see is so
difficult :s

from django.http import HttpResponse
from django.shortcuts import render_to_response
from myproject.parsing.models import Gente
from pyparsing import *
import itertools
from django.db.models import Q


def search(request):
errors= []
if 'q' in request.GET:
q = request.GET['q']
if not q:
errors.append('Escribe algo en la caja de texto')
else:
qlimpia=parseText(q)
for i in range(len(qlimpia),0,-1):
for lista in itertools.combinations(qlimpia,i):
filtro = Q()
for t in lista:
filtro = filtro & Q(tags__icontains=t)

#I think here is my problem, I can't concatenate the
query set in this way
negocios = negocios | Gente.objects.filter(filtro)
return render_to_response('search_results.html',
{'negocios': negocios, 'query': qlimpia})
return render_to_response('search_form.html', {'errors': errors})



def parseText(texto):
parser=OneOrMore(Word(alphas))
arreglo=("de","en","la")
for articulo in arreglo:
parser.ignore(CaselessLiteral(articulo))
salida=parser.parseString(texto)
for i in range(0,len(salida)):
salida[i] = " "+salida[i]+" "
return salida

return render_to_response('search_form.html')

Re: Controlling File Downloads.

[Matteius]

Please check the classcomm project for how to do this. We determined
the best/fastest approach would be to use Apache mod_auth_token and
generate secure URLs using a custom template tag.  You can find code
and instructions for how to do that @ http://classcomm.googlecode.com/
and across the Internet.  This is the best approach because the files
are severed off the web server pretty much like any static overheard
file.  Then in your view code you check a User's permission to the
file before generating them the time-sensitive URL.

Cheers!
Matteius

Why might a Django admin form hang (or, how can I diagnose the problem)?

[Michael Dippery]

I have a model tied to the admin. Whenever I try to add a new model instance, 
or update an existing one, the form hangs while trying to submit. Nothing is 
written to the log files, though. The models are nothing fancy, so they don't 
have any custom validation that may be causing, e.g., and infinite loop. Also, 
the hang only occurs on my production server, not on the staging server or my 
local development machine.

Any ideas as to what might be causing the hang? Or, since that's probably hard 
to answer without all the specifics of my setup and application, what's the 
best way to diagnose the problem?

That won't necessarily work. Some packages need to be compiled, so it would
only work if both environments are the same architecture.

mod_python is too old, I'm running fine with both nginx+mod_fcgi as well as
Apache+mod_wsgi.

As my namesake mentioned, I'd freeze your env and rebuild it using pip
install. Of course you have access to the cline on the server? :)

Re: incrementing non primary keys.

[Eric Chamberlain]

If you are using a UUID for the primary key, do you really need an integer?

virtualenv and deployment

[Álex González]

Hi!

I'm using virtualenv with --no-site-packages and now I like to do a
deployment of my app... I'm using a sharing hosting, can I uypload all my
enviroment dir (with the packages installed with pip) to the server and use
them?

What's the better way to the deployment? mod_python, mod_wsgi, perhaps
fast-cgi?

Thanks!

Re: Django-Facebook (yet another thread)

[da.inter...@gmx.net]

I had the same problems last weekend. This one here helped me a lot
and is actually working:

https://github.com/iplatform/pyFaceGraph

The tricky thing is how to get the access_token (Aljosa mentioned the
proper documentation). The graphdevtools-example-application under
"test" is also helpful here to get the token inside your application.

incrementing non primary keys.

[Hutch]

Hi,

I'm porting an old php app and have run into a bit of an issue. The
main problem is that we this app will need to be used by multiple
different companies. While I could just setup discreet instances, I'm
thinking that making the app multi-tenant would be a much wiser idea
and easier on resources, as traffic will be reasonably low, maybe
100-200 users a day. I also don't desire to deal with 4 installations
of the code, when one will do.

The specific problem I have though, is in the legacy app, the primary
key for a certain table is an auto incrementing integer. This needs be
kept separate for each tenant. What I'm planning on doing is making
the primary key a uuid, and using unique_together with an integer
field. However I could easily see a race condition with incrementing
the integer field. What is the best way to handle this situation?

Also, what is the best way of filtering based on the site_id? should i
store a setting with the session and filter based on that? I was
thinking about seeing if it's possible to use a middleware to change
it at run time based on the request url. Is that a good idea?

are there any documents on best practices for django multitenancy?

include() is meant to include an app's urls.py module, not to map a

Indeed.

Re-read the tutorial more carefully... and then the FineManual's
section about views and urls ;)


The common idiom is to have app-specific urls defined in the app's
urls.py module, then include this urls.py module from the project's
root urls.py, ie:

# hspoints/urls.py

from django.conf.urls.defaults import *
import views

urlpatterns = patterns('',
 (r'^/$', views.index),
 # your other app-specific url patterns here
   )


# urls.py

urlpatterns = patterns('',
 (r'^hspoints/$', include("hspoints.urls")),
 (r'^admin/', include(admin.site.urls)),
 )

Re: incrementing non primary keys.

[Eric Chamberlain]

If you are using a UUID for the primary key, do you really need an integer?

We had a similar multi-tenant need and didn't want to leak usage information to 
the users, so we used UUID instead of auto incrementing integers.

Re: No module named _md5

[Cal Leeming [Simplicity Media Ltd]]

http://www.google.co.uk/search?sourceid=chrome=UTF-8=%22No+module+named+_md5%22

That should help you figure out why it's not working :)

Try and figure it out first, and if you can't figure it out then you might
want to consider not using Python on Linux, because you will encounter many
problems like this throughout your time with python :)

Beginner Problem: I don`t get my view working

[josch]

Hallo,

I don`t know what is wrong with my code, but I can not call a view in
the urls.py of my site:

I have an application hspoints. In the folder is a views.py. In will
post a view files:


settings.py of my Site:

(...)
INSTALLED_APPS = (
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.sites',
'django.contrib.messages',
'django.contrib.admin',
'hspoints'
)
(...)


view.py of my application hspoints:

from django.http import HttpResponse

def index(request):
return HttpResponse("Hello, world. You're at the index.")


urls.py of my Site:

from django.conf.urls.defaults import *

from django.contrib import admin
admin.autodiscover()

urlpatterns = patterns('',
(r'^hspoints/$', include(hspoints.views.index)),
(r'^admin/', include(admin.site.urls)),
)


When i start the testserver with http://127.0.0.1:8000/hspoints/ I
get:

NameError at /hspoints/

name 'hspoints' is not defined


When I add import hspoints to the urls.py of my site, what I did not
have to do in the poll tutorial, I get:

AttributeError at /hspoints/

'module' object has no attribute 'views'



What am I do wrong? I just don`t get what I forgot to do...

Info: I`m working with PyDev in Eclipse.

Thank you!

You can convert the queryset to a list, then call the standard list sort 
method on it, passing the method as the key:

results = MyModel.objects.filter(criteria=whatever)
results = list(results)
results.sort(key=lambda x: x.my_method())

Obviously, as you note, this is not as efficient as doing the sorting in the 
database, but for small numbers of objects it should be acceptable.

Order a QuerySet by Method

[josch]

Hallo,

I know, that the normal way to do that is to write the return value of
the method to the foreign model, always when a model that affects the
return value changes, and than order by that value of the model.

But I have a model whoose objects gets a specific state after they are
older than a specific number of days. And i don`t want to use a
cronjob or something like that to update the foreign model`s value.

So, can someone tell me, how I can order a query set by one of the
function of it`s models, in a pinch by reordering the obecjts in a new
object array or some kind like that.

There are not a lot of records I have to order, so I think there is no
performance problem for my kind of application.

Thank you!

Re: Mailing list service written in Django?

[Steven Clift]

Thanks, we are quite bullish with GroupServer - much better web
interface than Mailman and while people like the utility of Google
Groups, GroupServer is customizable and you can control your group
data.

That said, since Django has come up in our new Neighborly work, the
more we know about existing code the better. (We are big believers in
tools that support email publishing in an integrated fashion.) The
quirky thing about Neighborly is the idea that each participant in the

Strange Admin CSS Behaviour

[Paul Childs]

I'm trying to use the Django admin (on the dev server that comes with
Django) for the latest stable version 1.2.3 on windows with Python
2.6. Functionally it works great.
For some reason the styles do not render for the site admin page and
my application admin page.
The respective URLS are: http://127.0.0.1:8000/admin/ and
http://127.0.0.1:8000/admin/asi/ where "asi" is my application.
All the other admin pages displaying properly: login, change pages,
list pages, change password, etc.
The only difference I see when I look at the source is that the pages
in question use dashboard.css instead of base.css.
I have tried moving the admin media directory to my project media
folder and serve it up myself but that did not seem to fix the
problem.
I uninstalled Django and reinstalled using a fresh download of 1.2.3.
I haven't come across anyone else having this problem either.
If anyone has an idea how to fix this or can point me in the right
direction to troubleshoot this, I would appreciate it.
/Paul

 Here are the media settings in my settings.py

# Absolute path to the directory that holds media.
# Example: "/home/media/media.lawrence.com/"
MEDIA_ROOT = ''

# URL that handles the media served from MEDIA_ROOT. Make sure to use
a
# trailing slash if there is a path component (optional in other
cases).
# Examples: "http://media.lawrence.com;, "http://example.com/media/;
MEDIA_URL = ''

# URL prefix for admin media -- CSS, JavaScript and images. Make sure
to use a
# trailing slash.
# Examples: "http://foo.com/media/;, "/media/".
ADMIN_MEDIA_PREFIX = '/media/'

Django comments moderation stopped working

[Groady]

Just wondering if anyone else is having problems with the Django
Comments Framework, specifically with the moderation functionality
stopping working.

Recently the moderation functionality has stopped working and all
comments are getting through without first being approved. I'm not
100% sure what it is that has caused this as it WAS working and now it
isn't. I have upgraded the Django installation to the latest version
recently so I have a feeling this may be the problem (though it
shouldn't be).

I have checked and double checked my code matches the moderation
documentation here: 
http://docs.djangoproject.com/en/1.2/ref/contrib/comments/moderation/.
It feels as if the moderator is being skipped over entirely as the
is_public field is set to True by default where is should be set to
False by my custom CommentModerator. Also my custom CommentModerator
has akismet code which normally deletes spam messages automatically
but this doesn't seem to be working (hence me thinking the moderator
is not being invoked at all).

Just wondering if anyone is having the same problem and if there are
any suggestion on how I might be able to debug this.

Re: Django-Facebook (yet another thread)

[Martey]

In my Facebook applications, I have used a combination of the official
Python SDK  and the official
JavaScript SDK . The JavaScript SDK takes care of authentication,
requesting permissions, and providing an access token, which I then
pass to the Python SDK in order to access information through the API.

There is, as far as I know, no official documentation involving Django
and the Python SDK, but one of the comments on a bug report asking for
a Django example suggested . I have not run that code, but
a cursory reading suggests that it would be helpful.

template filter by foreignkey

[refreegrata]

Hello list. I have a question. Whit a model like this
--
class Ghi(models.model):
   dat = models.IntegerField(unique =True)

class Def(models.Model):
ghis = models.ForeignKeyField(Ghi)

class Abc(models.Model):
defs = models.ManyToManyField(Def)
--
And from my view I return something like
Abc.objects.all()

Are some way to ask in the template something like:
exists in Abc.defs.ghis.dat == 1?

thanks for read.

Re: running projects on the back of a base URL and having issues with the homepage

[W. Craig Trader]

Here's how I solved this problem for my own applications.  Note that I use
VirtualEnv to ensure that each application gets exactly the Python
environment I want it to have.  If you don't use VirtualEnv, it will make
the WSGI startup script simpler.  Assume that my application is installed
with the following layout:

/data/web/foo/ -- base directory for foo (and the root of a VirtualEnv
environment)
bin/ -- VirtualEnv scripts, including 'python' symlink
lib/ -- Python libraries, including Django
apache/apache.wsgi -- Apache WSGI startup script
site/foo -- where the Foo site is installed (containing applications
like bar, baz, etc.)
site/foo/static -- where static content is stored

First, the Apache virtual host configuration:


  ServerName foo.example.com
  ServerAdmin f...@example.com
  ServerSignature email

  LogLevel debug

  WSGIProcessGroup  foo
  WSGIDaemonProcess foo processes=2 threads=5 home=/data/web/foo
display-name=foo

  DocumentRoot /var/www

  WSGIScriptAlias / /data/web/foo/apache/django.wsgi
  
Order allow,deny
Allow from all
  

  Alias /static/ /data/web/foo/site/foo/static/
  
SetHandler None
Order allow,deny
Allow from all
  


And now the WSGI startup script (most of this is just to make VirtualEnv
work):

import os, sys, site

here = os.path.abspath( os.curdir )

ALLDIRS = [
os.path.join( here, 'site' ),
os.path.join( here, 'lib', 'python2.6', 'site-packages' ),
]

# Remember original sys.path.
prev_sys_path = list(sys.path)

# Add each new site-packages directory.
for directory in ALLDIRS:
  site.addsitedir(directory)

# Reorder sys.path so new directories at the front.
new_sys_path = []
for item in list(sys.path):
if item not in prev_sys_path:
new_sys_path.append(item)
sys.path.remove(item)
sys.path[:0] = new_sys_path

os.environ['DJANGO_SETTINGS_MODULE'] = 'foo.settings'

import django.core.handlers.wsgi
application = django.core.handlers.wsgi.WSGIHandler()

In my settings.py file, I have the following:

import os, sys

SITEDIR = os.path.dirname( os.path.dirname( os.path.abspath( __file__ ) ) )

MEDIA_ROOT = os.path.join( SITEDIR, 'foo', 'static' )
MEDIA_URL = '/static/'
ADMIN_MEDIA_PREFIX = '/media/'

ROOT_URLCONF = 'foo.urls'

TEMPLATE_DIRS = (
os.path.join( SITEDIR, 'foo', 'templates' ),
)

INSTALLED_APPS = (
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.sites',
'django.contrib.messages',
'django.contrib.admin',
'foo.bar',
'foo.baz',
)

My urls.py file looks like this:

from django.conf import settings
from django.conf.urls.defaults import *
from django.contrib import admin
from django.shortcuts import render_to_response

# Uncomment the next two lines to enable the admin:
admin.autodiscover()

def home( *args, **options ):
return render_to_response( 'index.html' )

urlpatterns = patterns( '',
url( r'^$', home, name='site_index' ),
( r'^admin/', include( admin.site.urls ) ),
( r'^foo include( 'stackexchange.foo.urls' ) ),
( r'^bar include( 'stackexchange.bar.urls' ) ),
( r'^static/(?P.*)$', 'django.views.static.serve',
{'document_root': settings.MEDIA_ROOT } ),
 )

You only need the 'static' definition for when you're testing using
'runserver'; Apache intercepts all of the /static/ URLs before Django sees
them in production.

I hope this helps.

Update user page after thread execution

[mart]

Hello,

In my architecture, I send messages to a port object (implemented as a
queue in a thread). I'm giving callback function with the result of the
call.

For example, after filling the registration form,

# views.py
...
def createprofile(request):
...
gui_port.send_to(port_profile,('recordprofile',[arg1, arg2,..],
callback,
request))
return render_to_response('wait.html', locals())

def callback(request, status):
if status:
return render_to_response('success.html', locals())
else:
return render_to_response('fail.html', locals())


# profilemanager.py (the port object related to profiles)
...
# when received the message
try:
# some operations, update db,...
except:
# callback function with status = False
threading.Thread(target = msg[2], args = (msg[3],False)).start()
else:
# callback function with status = False
threading.Thread(target = msg[2], args = (msg[3],True)).start()


The problem is that (as expected) the callback function doesn't change
the user webpage when it happens.

Is there a way to do it (using AJAX maybe)

Thank you

Controlling File Downloads.

[NoviceSortOf]

What is the best way to allow authorized downloads
to specific users in Django.

We have 2 possible scenarios that could work for us.

1. A download directory where any user can download any
   file in the folder.

or

2. Granting specific rights to specific users to download a specific
file
or set of files.

Any suggestions?

I wrestled with something like this - as we needed a static homepage
based on a django backend for one site.

Per my recollection what I did was.

* Apache httpd.conf required a location match adjustment something
like.


  SetHandler None


* My url.py file needed this line
  (r'^$', direct_to_template,{'template': 'index.html'}),

* As well I landed up having to put the index.html into both
  full static form in the .com root as well in the django template
folder.
  This was neccesary so people could load into the site as
  "www.somewhere.com"
   and while once in the django backend
  "www.somewhere.com/index.html" would load for further
   navigating.

I hope that makes sense, there was a downside to this in that
our web provider Verio's site management front end does not work
with us resetting the SetHandler in the root. In any case
most management of this site is done on the command line level.

Not a perfect solution but one that works, I'm open for other
suggestions.
