And it comes back to normal after back to version 1.2.

Like I said, installing python-django isn't canonical, but no body said it's
inherently wrong.

It's standard practice among the Python community to install and manage
packages through either pip, easy_install or other python tools. Creating
isolated virtual environments with custom PYTHONPATHs is very common as
well.

Having said that, I wonder why [1] i'm still finding Django 1.2 as the
shipped version for the Debian's stable release. Are you running wheezy by
any chance?

Proper way to strip whitespace from Charfields in a form in current version of Django?

[br]

There seems to be a raging and unresolved discussion about how to
address the issue of stripping whitespace from form fields in future
versions of Django over on the Developers group:
http://groups.google.com/group/django-developers/browse_thread/thread/90352cc0da78390b
.

In the present, what is the proper place to strip whitespace?

I've starting down this path:

http://www.peterbe.com/plog/automatically-strip-whitespace-in-django-forms

by setting up a BaseModelForm class, but i don't necessarily like the
fact that I could have a field with "blank=False" that will still
validate if you have an input of just whitespace, since apparently
"clean" gets called after validation takes place.  Is the override of
full_clean referenced in the comments the way around this then? Seems
pretty hacky.

Thanks

Ben

POST requests that don't send any data - Django development version 1.4.0 Alpha

[Jesse]

I'm not sure if this is a bug (though it probably is) and wanted to
review here before submitting a report. Consider the following
handler:


def test(req):
if req.method == "POST":
HttpResponse("the request was a POST")
else:
HttpResponse("the request was not a POST")


This works as long as the client doesn't send any data. However, if
any data is included in the request payload, the HttpResponse call
mysteriously fails and redirects to [origin]/internal_error.html which
in turn ends up as a 404 if you don't have such a page in your public
directory or a catch all handler.

Trying to catch this exception is impossible because the handler has
to call HttpResponse at some point. Since there is no way to control
whether the client decides to send data, (even if they shouldn't) this
appears to result in an un-handleable circumstance. Is this the
intended behavior, a bug or am I crazy for some other reason?

*An additional point of interest - changing the handler to access
req.POST anywhere before HttpResponse is called, even if the actual
data isn't processed or examined directly, seems to solve this problem.

You can do exactly that, except without the () brackets. You'll need

Currently, there are about 200 accounts, but the entries for every month
only refer to a subset of them (about 50 each month). However, the entries
can refer to accounts that weren't referenced on the previous months,
including new accounts. Moreover, even though the entries refer to say, 50
accounts, the admin might only want to show the report for 40, or perhaps
display an extra account (that didn't get imported) with a hard coded value.
They might also want to manually enter a value for any account, if, for
example, something was missing in the original .csv or if the total value
was wrong.

Monthly Account values are derived from a sum of all the entries' values
that have an FK to that account in a given month.

Entries are 1.5 million rows/month, with small values, and accounts are
referenced hundreds of times in the .csv file, with the same date, user and
sometimes text. The value can vary, but not necessarily. So I do some
aggregation in the entries to get the account value.

These accounts are "groups" of entries that for accounting purpose have been
given a code. Think of it as a way of grouping different account
payables/receivables, so you have, say code M1023910240 for "subscriptions"
(+), D102512509 for "discounts" (-), M91212050592 for "SMS usage".

I wanted admins to be able to draft the report and have a final, published
report to go on the main page (this one would need to be unique for
month/year), so that they can switch back and forth between versions.

The problem is I'm supposed to have millions of entries; all with the same
date, thousands for the same Account, hundreds with the same description and

Hi Andre, Could you elaborate a little more about the monthly reports?
The admin pick up some arbitrary number of accounts and the app generates a
global report for those accounts? or it should generate a discret report for
each account?

2. If so, how can I ensure there's only one official monthly report? Perhaps

 what's the difference between "official monthly report" and  "unofficial"

As you say, when a user upload a csv file you could check if your db already
contains entries for the same month and if so, display a confirmation page
warning the user that someone already uploaded the csv for the current month
and if it's ok to delete the entries of the previous importat. (show some
details: user/date/csv version|name/#entries and so on) .

Render nested queryset in a template ?

[kooliah]

I need to render a nested queryset in a template, a classic father/son 
structure like

publisher>dvds>renters,

code 
---

class publisher(models.Model):
publisherid = models.IntegerField(primary_key=True)
publishername = models.CharField(max_length=135, blank=True)

class dvds(models.Model):
dvdsid = models.IntegerField(primary_key=True)
dvdsname = models.CharField(max_length=135,verbose_name='Corp.Name')
publisher_publisherid = models.ForeignKey(publisher, 
db_column='publisher_publisherid')


class renters(models.Model):
rentersid = models.IntegerField(primary_key=True)
rentersname = models.CharField(max_length=135, blank=True)
dvds_dvdsid = models.ForeignKey(dvds, db_column='dvds_dvdsid')
---

in python code i can use this code:

code 
---

pub= publisher.objects.get(publisherid=1)
for disk in pub.dvds_set.all():

See the very good documentation on FastCGI setup:
https://docs.djangoproject.com/en/1.3/howto/deployment/fastcgi/
- it even has a section specifically on lighttpd.

Re: Django site broken after Debian upgrade

[Andre Terra]

Django has a policy of warning about deprecations for two versions and
finally dropping support on the third dot release.

Installing the python-django package is not the canonical way of using
django, let alone running production servers.

Perhaps you have a replica of the old admin templates on your
project's folder which might be overriding the files shipped with
core, so take a look at that first.

If nothing else works, disable the csrf middleware and you're good to go.

Cheers,

Accounting app - design decisions needed

[Andre Terra]

Hello, django-users.

I'm in need of some serious help on deciding how to design my next project.
Below is my attempt to describe the use case:

*USE CASE*
I'm writing an accounting app that will be generating unique monthly reports
of the revenue results for a list of Accounts (model) in the company.

Each Account has a set of instances of Entry (model) with a Decimal value,
date and some text, as well as a FK to Account.

These entries are uploaded through an (already coded) import function which
parses a .csv and, using DSE, inserts 1.5 million rows to the Entry table.
These entries also have an FK to Task (model) so I know which import process
generated them.

Each month I want to allow an admin to pick a set of Accounts to be
displayed in the monthly report, which needs to be unique for obvious
reasons.

*CODE
models.py
*http://dpaste.com/hold/570933/

*example .csv file to be imported* (importing the file is already coded and
works 100% so far)*
*http://dpaste.com/hold/570934/*
*
*QUESTIONS*
1. Should I create another model named MonthlyReport with an M2M relation to
Accounts, and then add an 'is_active' flag so I know which one is the
official monthly report?

2. If so, how can I ensure there's only one official monthly report? Perhaps
setting is_active to False to all the other MonthlyReports that carry the
same month/year?

3. How should I prevent users from importing the Entries more than once?
Forcing a deletion of entries for the same month as the imported entries is
a possible solution.. The .csv file should always be restricted to a single
month, but I guess I could write a check for that too, or expand the
deletion for every matching month.



As you can see, I have a few ideas on how to proceed, but it would be great
if anybody could weigh in on this, as the deadline is incredibly short (1
month including views/templates, etc).

I thank everyone in advance for reading through this and for any help they
can offer.

Cheers,
André

get django/lighttpd "hello world" page

[Phil]

Hi,

I have an ubuntu server, django is fully installed and working,
lighttpd is installed and working(works with standard html page), but
I am not sure how to get them talking to each other?

It is my first time putting a django site onto a live server so any
help is appreciated. I'm used to a php "stick everything into webroot"
setup.

I have the following in my lighttpd.conf file as mentioned on django
website

server.document-root = "/var/www"
fastcgi.server = (
"/mysite.fcgi" => (
"main" => (
# Use host / port instead of socket for TCP fastcgi
"host" => "my ip address",
"port" => 80,
#"socket" => "/home/user/mysite.sock",
"check-local" => "disable",
)
),
)


At present all that is doing is loading my html page in my webroot. I
have restarted lighttpd and all. But not sure how it see's django
project?

Thanks.

Django site broken after Debian upgrade

[bkline]

I just upgraded my Debian server, which brought the python-django
package up to version 1.2, and now any attempt to post to the database
tables results in a CSRF failure.  I'm using the admin pages to do
just about everything, so it not clear how to apply the instructions
in the Django CSRF docs [1].  Those documents say "The utility script
extras/csrf_migration_helper.py can help to automate the finding of
code and templates that may need to be upgraded. It contains full help
on how to use it."  That script is not among the many files installed
by the package.  Right now I've got things working by hacking the core
code and disabling the lines which are returning the failure, but
that's clearly not a good long-term solution.  Breaking sites like
this with a dot-release which isn't backwards compatible is
disappointing, to put it politely.  Unless I can get this working the
right way I'm going to have to dump Django and port the site to some
other package.

Re: trouble going from django on Windows to Ubuntu using Eclipse & Aptana Studio

[Fatrix]

I didn't aim to start a discussion about which IDE is better. But
every one has its own pros and cos.

While working with Aptana I had to recreate several times a broken
workspace, a really annoying work.
That was my main reason to switch from the free Eclipse-World to the
(not expensive) PyCharm
world.

For me the most significant feature a IDE must provide is a vi-mode.
No fun without vi.

Re: syntax

[Andre Terra]

There is an error because you are concatenating the function _() and the
string '%s: %s \n'

You also don't need the space before \n

and don't add unnecessary spaces: (the_waybill, str(errorObj.code)) is the
right way to write the last part of the code[1].

there is an error in this statement. i do not know if this is a valid

becoz what i want to assign to self.errormessages is Problem with data
of waybill (-value in- -variable  waybill--) : (errorobjcode) .
Problem with data of waybill is a translatable string.

Re: syntax

[Cal Leeming [Simplicity Media Ltd]]

Something like this?

_str = _('Problem with data of Waybill')
_str2 = "%s: %s \n" % ( the_waybill, str( errorObj.code ) )
self.ErrorMessages = "%s %s" % ( _str, _str2)

using signals to add users to a group

[Andrew Marder]

Dear Django Users,

I want to add users to a particular group based on the domain of their
email address. I set up some code in models.py to do this and it seems
to work. But, when I go to test the code things don't work out so
smoothly. I think in the test environment the objects I try to create
in models.py may not be inserted in the test database. Any ideas for
good work arounds?

IPAddressField appears to be v4 only for backwards compatibilty reasons,
GenericIPAddressField covers both, so in theory I've got no problems
with that, other than it making IPAddressField backwards incompatible
which seems silly at this point, and I'd be recommending people to be
using GenericIPAddressField anyways.

OTOH, for really huge database tables, making the index 4 times
smaller can be a significant difference on RAM-starved servers
but to fill 1G can hold something like of 50million IP addresses in

Re: Storing IP address as integer within database to remove need for full text search

[Cal Leeming [Simplicity Media Ltd]]

Or maybe you were talking about hash tables in MySQL.

Either way, you're right that this would probably need some benchmarks
before being approved for the core.

@django-developers, if I was to provide some benchmarks, would this possibly
be considered for the core?

Storing IP address as integer within database to remove need for full text search

[Cal Leeming [Simplicity Media Ltd]]

Hi,

I have created a ModelField called RealIPAddressField.

It stores the IP address in integer form, meaning the lookups on large
tables are much faster:

http://djangosnippets.org/snippets/2493/

@django-developers - Do you think there is any possibility of this getting
included into the core?

@django-users - Hope this is of some use to someone else, would appreciate
any criticisms / improvements.

Getting the DJANGO_SETTINGS_MODULE correct is all that's needed. I've
never created a management command, nor needed to.

If all you want to do is use Django models in a script there's no need
for anything else.

Re: Django - can't open image in model save()

[br]

Not sure if this is your problem but there are some issues with some
PIL installations and JPG files that require some potential
configuration/install-time magic, so make sure you test on PNG's or
GIF's first and make sure its working with those.  If it ends up being
JPG-specific issue, and google doesn't turn up the work-through for
it, post here, and I can dig up the blog posts I used to resolve my
JPG issues with PIL and Django's ImageField.

Re: import django models without runing the server

Hi Malcom,

I am not sure the management commands are what I want, but the setting
of the DJANGO_SETTINGS_MODULE environment variable helped. I had
experimented with these settings already, but wasn't successful until now.

So, thanks for the help!

You should be able to pass SpectacleGallery.image to PIL open - I've done
similar things in the path.

What happens when you step through the code - what's the value of
self.image? Is it really a valid image file? Is it where it thinks it is?

Re: Class-Based Generic Views (CreateView) - field exclusions and defaults

[br]

While this doesn't contribute an answer to your question, I must say
that name "class-based generic views" is a bit misleading . . .
implying that these class-based views are for doing things you want to
do that follow a strictly set pattern out of the box (i.e, listviews,
detailviews, create views, etc.), but that you'll have to use
something else (i.e., function based views) if you are defining your
own views.  However, this is not the case at all.  We wanted to switch
all our views to class-based, and have had great success with writing
our own class-based views by extending built-in view and mixin
classes.  Basically, most of our own views extend the generic
TemplateView and we add in our own Mixins or add functionality to the
overridden class methods. Some of our views extend other generic view
classes. As the documentation gets updated and edited, this paradigm
probably ought to be explained, because for a while I just figured
that i still had to still use function views if I wanted to do
anything custom, beyond what the generic views provide in and of
themselves.  They're a different beast but can be much more DRY and
add some OO awesomeness to your code once you get your head around
them.  For now, I'd recommend looking at the source code to see which
functions you can override, its pretty straightforward.

Much easier than doing things manually.

import django models without runing the server

[Alexander Crössmann]

Hi,

I want to write a python script that works with django models without
runing the server. My OS ist Ubuntu 10.10.

My skipt looks as follows:

import sys
sys.path.append('/home/myname/python/django_projects/')
sys.path.append('/home/myname/python/')
import settings
from django_projects.codierung.models import *

The settings work fine with testserver and apache but wenn I run the
that skript I geht the following error:

ImportError: Settings cannot be imported, because environment variable
DJANGO_SETTINGS_MODULE is undefined.

What else do I need to define appart from the stuff that is allready in
the settings file? I read the page on settings in the documentation but
that wouldn't help me.

Thanks for any Help!

Thanks Chang.Jian,


Goth

test_url = reverse('test.views.index', args=['slug'])

and 

test_url = reverse('test.views.index', kwargs={'some_slug': 'slug'})

work as expected... 

reverse('test:index', args=['slug']) would be the desired syntax, but the 
other will work fine as a work around. Anyone know if this is a known issue 
with the dev team? My Google searches didn't come up with much.

Re: trouble going from django on Windows to Ubuntu using Eclipse & Aptana Studio

[Cal Leeming [Simplicity Media Ltd]]

Personally, I absolutely hate Eclipse and anything associated with it.

An IDE really comes down to personal preference, which is why there are so
many of them.

I'd like to throw Komodo in the mix. I moved from NetBeans to Komodo about 2
months ago, and haven't looked back since. Although Komodo could be
improved, it's the best I've found so far.

Aptana is *very* prepared for Django, including (but not limited to) (some
degree of) support for the template language.

It's also *free as in beer*, which PyCharm is not.

I personally like Aptana because it's incredibly easy to browse my source
code, with hyperlinks and visual cues to required args and kwargs, not to
mention docstrings, etc.

It also has some degree of support for django templates and allows you to
configure different python interpreters (i.e. virtualenvs) that can be used
for running your project from within the IDE or through debugging with
breakpoints.

Now about the OP, this is the reference you should be following:

Pinboard.in links on Django Community feeds page usually don't work.

[swiharta]

With the rise in popularity of tagging Django links using Pinboard.in,
it would be nice if the links on the feeds page actually worked. The
titles come across fine, but the url's usually just point to the
pinboard.in homepage. I just highlight the title and Google it to find
the page, not a lot of work, but definitely suboptimal. I don't know
if this forum is the right place to report this.

USE_I18N vs. USE_L10N

[Lucy Brennan]

I believe I understand the general definitions of internationalization
and localization, e.g. as defined on 
http://en.wikipedia.org/wiki/Internationalization_and_localization.
Internationalization is somewhat like building/designing a piece of
software for being used with different locales. And localization is
then making some localized version withing the boundaries set by the ,
e.g. making all the translated versions and date formatting for
Germany.

According to those definitions, I think it makes sense to "turn off
i18n and l10n". But what does it mean to turn of one and not the
other?

They only make sense in relation to each other, and turning one of
without turning the other off, does not make sense to me.

I don't think it is obvious what they do?

Compare and contrast what you have for ENGINE, and what the example

I use a symbolic link to the static admin files of django instead of

That link works - when I go to http://inventory/static/admin is can see 
the css/img/js folders for admin.



I just tried to set admin_media_url but it doesn't work either.

You should probably take a look at:

* Multiple DB:

When I go to http://inventory/admin, the static/admin files are not

When I check the page source, it shows

Re: trouble going from django on Windows to Ubuntu using Eclipse & Aptana Studio

[Fatrix]

Hi Doug

Perhaps [0] on stackoverflow helps you solving the problem (--noreload
option).
As I remember I had the same issue within Aptana.

-V, before using PyCharm I was also developing with a simple editor
(vi).
Aptana wasn't a good choice, because the support for Django isn't
built-in.
PyCharm doesn't face you with these kind of problems, because PyCharm
is very well
prepared for Django-based applications.

Regards,
Philip
