However, you have to use a registered nickname -- you can't just join the
channel. Registering your nickname costs nothing, but ensures that nobody
in the #django channel (or any other channel for that matter) can pretend
to be someone they aren't.

how to tricking LogEntry model ?

[Bino Oetomo]

Dear All ..

I Try to write a custom auth backend.
It'll use external user model/table, let's call it 'myuser'

With this scenario, the LogEntry will receive a user_id that not exist
in default User model.
So it will generate exception.

I read that we can do a 'pre_save' signal receiver for LogEntry
http://stackoverflow.com/questions/4176238/django-extending-logentry

Now, I have this ini myproject/management/__init__.py

--START-
from django.db.models.signals import pre_save
from django.dispatch import receiver
from django.contrib.admin.models import LogEntry

print 'THIS IS LOGENTRY PRE-SAVE'

@receiver(pre_save, sender=LogEntry)
def mypresave(change, **kwargs):
print 'PRE SAVE, CHANGE ', kwargs
--STOP--

and when I 'runserver', looks like it is loaded
START---
^Cbino@bino-pata:~/Documents/django/mas/mas01$ python ./manage.py
runserver
THIS IS LOGENTRY PRE-SAVE
THIS IS LOGENTRY PRE-SAVE
Validating models...
0 errors found
Django version 1.4.3, using settings 'mas01.settings'
Development server is running at http://127.0.0.1:8000/
Quit the server with CONTROL-C.
STOP

But when I try to do some change on my data, the debug console didn't
print any thing form 'mypresave'

Kindly please tell me how to do it properly.
and also ...how to tell LogEntry to do nothing for any signal from
some specific models ?
Since I plan to make a model that have one-to-one relation to
LogEntry, and want logentry do nothing when something write to this
model.

Sincerely
-bino-

Ordering a QuerySet based on a latest child models field

[Sven Grunewaldt]

Lets assume I want to show a list of runners ordered by their latest sprint 
time.

class Runner(models.Model):
name = models.CharField(max_length=255)

class Sprint(models.Model):
runner = models.ForeignKey(Runner)
time = models.PositiveIntegerField()
created = models.DateTimeField(auto_now_add=True)


This is a quick sketch of what I would do in SQL:

SELECT runner.id, runner.name, sprint.time
FROM runner
LEFT JOIN sprint ON (sprint.runner_id = runner.id)
WHERE 
  sprint.id = (
SELECT sprint_inner.id
FROM sprint as sprint_inner
WHERE sprint_inner.runner_id = runner.id
ORDER BY sprint_inner.created DESC
LIMIT 1
  )
  OR sprint.id = NULL
ORDER BY sprint.time ASC


The Django QuerySet documentation states:

> It is permissible to specify a multi-valued field to order the results by 
> (for example, a ManyToManyField field). Normally this won’t be a sensible 
> thing to do and it’s really an advanced usage feature. However, if you know

I guess I need to apply some filter here, but I'm not sure what exactly 
Django expects...

One note because it is not obvious in this example: the Runner table will 
have several hundred entries, the sprints will also have several hundreds 
and in some later days probably several thousand entries. The data will be 
displayed in a paginated view, so sorting in Python is not an option.

The only other possibility I see is writing the SQL myself, but I'd like to 
avoid this at all cost.

Test database not auto-flushing

[Matt]

 

I have a bunch of unit test files, all of which consist of 
django.test.TestCase classes.

Wrote myself a little shell script to uncomment/comment test file imports 
in my __init__.py file, so I can run tests from certain test files, based 
off the command line arguments I give it. I am also able to run all the 
tests of all the test files in one go (for regression testing purposes).

I have this one test file that has some JSON fixtures and the first test 
checks that a certain model/table has 3 records in it (defined by the JSON 
fixture).

So here is the problem: when I run this test file on its own its tests pass 
with flying colours, but when I run the test with all other tests, that 
particular test case I mentioned, fails.

When I run all the tests, the database says there are 6 records in the 
table/model, but there should only be 3 (from the fixture), like when the 
test file is run by itself.

I also tried running the that test file with a few other test files (not 
all) and it passes. So the only time it doesn't, is when all the test files 
are run.

To me this seems like a bug in Django or PostgreSQL (DB I am using), 
because aren't Django TestCases supposed to auto-flush/reset the database 
between each test method, let alone test class?

Posted on stackoverflow (
http://stackoverflow.com/questions/15124828/django-test-database-not-auto-flushing),
 
but haven't got a response yet.

Can you explain why you don't want to use for? Seems perfectly sensible to 
me, a formset contains multiple forms so you need to use a loop.

Django save method in infinite loop, code review?

[sparky]

Django newbie :) I'm wondering if you *kind people* could help me work out 
how to solve a little issue I'm having :) I'm using *S3 storage* via the 
package django-storages .

The following code gets stuck in an endless loop. I know  just enough to 
know why, but not how to solve...

*Remembering I'm a newbie*


This is what the the code I have written does so far

1) profile gets saves and image uploaded *(without the resize of course)*to S3 
- 
*PERFECT*
2) the full size image is then read from S3 in the image_resize function 
and resized and renamed in the database - *PERFECT*
3) old large image get deleted from S3 - - *PERFECT*
4) it is then saved on this line   *self.image.save *and continues it all 
over again in a *infinite* loop! - ERROR  


def save(self, *args, **kwargs):
# delete old file when replacing by updating the file
try:
this = Profile.objects.get(id=self.id)
if this.image != self.image:
this.image.delete(save=False)
except: pass # when new photo then we do nothing, normal case
super(Profile, self).save(*args, **kwargs)
if self.image:
image_resize(self)


def image_resize(self):
import urllib2 as urllib
from cStringIO import StringIO
from django.core.files.uploadedfile import SimpleUploadedFile

'''Open original photo which we want to resize using PIL's Image 
object'''
img_file = urllib.urlopen(self.image.url)
im = StringIO(img_file.read())
resized_image = Image.open(im)


'''Convert to RGB if necessary'''
if resized_image.mode not in ('L', 'RGB'):
resized_image = resized_image.convert('RGB')

'''We use our PIL Image object to create the resized image, which 
already
has a thumbnail() convenicne method that constrains proportions.
Additionally, we use Image.ANTIALIAS to make the image look better.
Without antialiasing the image pattern artificats may reulst.'''
resized_image.thumbnail((100, 100), Image.ANTIALIAS)

'''Save the resized image'''
temp_handle = StringIO()
resized_image.save(temp_handle, 'jpeg')
temp_handle.seek(0)


''' Save to the image field'''
suf = 
SimpleUploadedFile(os.path.split(self.image.name)[-1].split('.')[0],
 temp_handle.read(), 
content_type='image/jpeg')
self.image.save('%s.jpg' % suf.name, suf, save=True)

Re: Django save method in infinite loop, code review?

[sparky]

I did actually try that but if I do this...


# Resize if we have an image.
> if self.image:
> image_resize(self)
>
> super(Profile, self).save(*args, **kwargs)
>

then inside image_resize 'self' is the old image and I get a 404 error on 
the line...

 img_file = urllib.urlopen(self.image.url)

Re: how to create formset field but not used loop in template

[C. Kirby]

I do sometimes reference formset forms individually without the loop. 
Allows me to better create my layout.
As for your question Witold, list items in a template can take an index to 
select a single item. This will only work if you know how many forms are in 
your formset:

{{formset_create_company.[n].no_house}}

where [n] is the index of your form (1,2,3,4...)

Experiences with A/B testing?

[Tomás Solar Castro]

Hi everyone

I want to make some A/B testing. I've searched for how to do this with 
django, and I found some extensions:


   - django-lean https://github.com/suckaplease/django-lean (seems 
   discontinued)
   - django-ab https://github.com/johnboxall/django-ab  (seems discontinued)
   - waffle http://waffle.readthedocs.org/en/latest/
   - gargoyle https://github.com/disqus/gargoyle
   - splango https://github.com/shimon/Splango

Last three have active development, but they are for feature flipping 
(only?). Maybe mixing that with google analytics or something could work?

Anyone have some experiences with A/B testing?

Thanks in advance

Re: Django save method in infinite loop, code review?

[sparky]

right *OK* now I get it. see, just needed a little push in the right 
direction...


so I moved super up
I then changed to use  resized_image = Image.open(self.image)
I then changed *self.image.save('%s.jpg' % suf.name, suf, save=False)

*and* BOOM! *all working!*

Thanks so much, this is so fun!

I didn't reply to your fastcgi posts yesterday, as you were attempting
to have everything spawned by the web server, which is not how I have
my fastcgi sites setup. If you are happy with running the web app
separately yourself, then this recipe will work:

Apache httpd with mod_fastcgi:

RewriteCond %{REQUEST_URI} !^/media
RewriteCond %{REQUEST_URI} !^/
# repeat for any other directories you want httpd to serve
RewriteRule ^/(.*)$ /app.fcgi/$1 [QSA,L]
FastCGIExternalServer /path/to/your/htdocs/app.fcgi -socket
/path/to/your/webapp/run/app.socket

Then simply ensure you have started your app:

python project/manage.py runfcgi \
socket=/path/to/your/webapp/run/app.socket \
pidfile=/path/.../run/app.pid \
errlog=... outlog=... \
minspare=.. maxspare=...

For absolute clarity, there is *no* real file named 'app.fcgi'. It
does not exist, it has no contents, it is merely a location in
urlspace - although you specify it as a filespace location! - that is
used to specify to fastcgi to take over the request. This is the
opposite of wsgi!

Is there a reason you are not using wsgi by the way? This is the
preferred method of hosting python apps, we used fastcgi as we are not
only hosting python apps.

Cheers

Tom

django-registration vs Django 1.5

[Xavier Pegenaute]

Hi,

seems django-registration doesn't support properly the new user model 
from Django 1.5, any one know how to work around it, or at least some 
other application able to deal with Django 1.5?


Thanks,
Xavi

Django URLs with/without proxy server

[Barun Saha]

I have two Django apps (say, app1 and app2) hosted on the same machine 
using Apache mod_wsgi. These two apps are hosted on two different 
environments:

 1. On a physical server where only these two apps are hosted. They are 
accessed as http://www.example.com/app1/app1/ and 
http://www.example.com/app2/app2/.
 2. In the second environment there is a proxy server. A separate web page 
on that server is accessed as http://www.domain.com/. This links to the 
above two apps (now hosted on a single virtual machine) as 
http://www.domain.com/id1/ and http://www.domain.com/id2/

The URLconf file looks like:

urlpatterns = patterns('',
(r'^admin/', include(admin.site.urls)),
(r'^app1/', include('project.app1.urls')),   
)

The problem is, this URL configurations works in the environment 1, but not 
in the environment 2. Now, if I do something *crazy* in the environment 2 
such as  

 urlpatterns = patterns('',
(r'^admin/', include(admin.site.urls)),
(r'^app1/app1/app1/', include('project.app1.urls')),   
(r'^app1/app1/', include('project.app1.urls')),   
(r'^app1/', include('project.app1.urls')),   
 )

then the application works. In the env. 2, the app is accessed as 
http://www.domain.com/id1/app1/app1/.

I couldn't understand why we need to prefix app1 in the URL so many times. 
In other words, why (how) this works.

Could someone clarify on this? Also, note that all configurations need to 
be done on the virtual machine. I don't have access to the proxy server.

Django + Raspberry PI

[Nicolas Emiliani]

Hey guys!

Has anyone tried to run django + sqlite on a raspberry pi ? Any performance
issues ?

I'm about to start an app that provides a restful api and has to run on
RPI, it's going
to manage an automation service, so load is going to be pretty low.

Cheers.

Re: Django + Raspberry PI

[Shawn Milochik]

Yep, I got my full development environment for one of my company's
applications running on it with almost no problem. The one exception
was MongoDB, which is for x86 only, so I had to compile a fork, which
took about 10 hours on the Pi.

It was definitely pretty slow, but it works.

Our stack includes nginx, gunicorn, Redis, MongoDB, PostgreSQL,
supervisor, virtualenv, and probably other stuff I'm forgetting.

It is a computer, after all. Just slow, not too much RAM, and with an
ARM processor.

Re: Django IRC & sqlite3 .schema

[Dorian Kiss]

Cheers, I'm sorted on the IRC now. Before I asked I did look for the search 
button, everywhere except the huge search bar at the top. After I posted 
the question I found it, and found your previous answer about IRC, but 
unfortunately there was no option to delete or edit my topic.

As for the sqlite3 question: I've django-admin.py startproject mysite; 
configured mysite/settings.py and python manage.py syncdb. So, I have a 
sq3.db sqlite3 database in the outer mysite directory:
mysite/
manage.py
sq3.db
mysite/
__init__.py
settings.py
urls.py
wsgi.py

I've then tried to proceed by following: 'If you’re interested, run the 
command-line client for your database and type \dt (PostgreSQL),SHOW TABLES; 
(MySQL), 
or .schema (SQLite) to display the tables Django created.'

I don't know what the command-line client for my database is(I'm using the 
windows(DOS) 'Command Prompt', but after searching Google I came across the 
web page 'http://curioushq.blogspot.co.uk/2011/05/django-tutorial.html', 
which says: 
'So on the command prompt, I type in sqlite3 nameofdbcreated.db and then 
once inside, type in .schema to create and list the databases.' 

Though, when I enter 'sqlite3 sq3.db' from within either C:\ or my outer 
mysite folder I get the response: 'sqlite3' is not recognized as an 
internal or external command,
operable program or batch file.'

Of course, I haven't gotten any further than that.

I have wondered if this is because I need to set up a path inside the 
windows environment variables like I did(though apparently unnecessarily) 
for Django as a whole.

Re: Converting Django app into a Desktop app

[Kevin London]

Oh okay, interesting. Thank you for following up. I'm going down the
Pyinstaller route, I think. Support for Django in Pyinstaller is so recent
that I'm hitting a number of snags, so I might need to go py2app if it
doesn't pan out yet. Thanks to everyone so far for their contributions,
this has been a very helpful thread in working through the distributing
problem.

Getting only the models related to my queryset.

[Gabriel Koscky]

Hi, I've been having some trouble with filtering the related models of a 
queryset,
and I'm not sure if I'm approaching this wrong or if Django can't actually 
do it.

Basically I have some models with ManyToMany relationships, like:

*class User(models.Model):
name = models.CharField()
class Product(models.Model):
name = models.CharField()
class Order(models.Model):
user = models.ForeignKey(User)*

*status = models.CharField()*

*products = models.ManyToManyField(Product, through='OrderProduct')
class OrderProduct(models.Model):
product = models.ForeignKey(Product)
order = models.ForeignKey(Order)
amount = models.IntegerField()*


And I want to get all the products bought by User1, so I'd do something like

*Product.objects.filter(order__status='completed', order__user=User1)*

Which then returns just Product1, but now I want the amount the user bought,

but it seems wrong to make another query like:

*Product1.orderproduct_set.filter(order__user=User1)*

And hit the database again to get data my first query can already bring me...


So what I want to know is, based on a queryset that filters by related models,

is there a way to get just the actual related models of my result?


Thanks,

Gabriel

Request for comments on a new Open Source Paas platform for Django

[Patrick]

Hi,

I'm building a Juju based Open Source Paas platform for Django and
I need your help because it is a hard task to make a PAAS system
that is flexible enough to deploy any projects and at the same time
simple to use.

For the ones that don't know Juju, it's a service orchestration software
compatible with LXC (local), EC2, HPCloud, OpenStack and Baremetal/Maas
developed by Canonical (the company that makes Ubuntu).

Check out the web site for more details: https://juju.ubuntu.com/

So quickly, here's how it would works:

After installing Juju and configuring it with for your favourite cloud 
provider you
will need to create a configuration file in the YAML format named 
my_django_conf.yaml
in this example::

  my_django_site:
  vcs: git
  repos_url: https://github.com/my_username/my_site.git 
  site_secret_key: abcdefgh123456789
  use_virtualenv: True

Then you will need these commands to bootstrap and launch all the servers::

  juju bootstrap

  juju deploy --config my_django_conf.yaml my_django_site
  juju deploy postgresql # or mysql,mongodb, etc
  juju deploy gunicorn # Or mod_wsgi, etc

  juju add-relation my_django_site postgresql
  juju add-relation my_django_site gunicorn

  juju expose gunicorn # Open the tcp port in the firewall

You will end up with 3 servers running. One will be the controller
and one for each service (django and the database). 
Gunicorn will be a special charm that will be installed on your Django 
server.
After that, adding a new Django node would be as simple as::

  juju add-unit my_django_site



As I said, where it gets tricky is how do I make the configuration flexible 
enough
and at the same time simple.

After looking at what was existing in Django's Paas world, I came with this:

1 - We need a configurable requirements files for both pip and apt-get. By 
default
it would be looking for package in there files at install time::

  requirements_pip_files: requirements.txt,requirements.pip
  requirements_apt_files: requirements.apt

and we could also configure extra packages by adding variables like this in 
the YAML file::

  additional_distro_packages: vim,emacs,etc
  additional_pip_packages: virtualenvwrapper,celery,South,etc

2 - I'm suggesting to use separate configurations files in a settings/ 
directory
so by default it will be injecting configuration in those files::

settings_database_path: settings/20-engine.py
settings_static_path: settings/20-static.py
settings_uploads_path: settings/20-media.py
settings_cache_path: settings/30-cache.py
settings_secret_key_path: settings/20-secret.py

I'm suggesting splitting settings because when the configuration is 
modified,
for some reason, it would be difficult and risky to parse settings.py and 
change only the right thing.

So instead, I would be using topic files rendered with templates.
So if you would need to do more advanced stuff you could just fork the charm
and modify the templates for your needs.

3 - Finally, I was thinking adding some options to execute custom scripts 
that
would run a various time during the deployment. Like after packages 
installation
,database configuration and static file configuration::

post_database_script:
type: string
default: |
  #!/bin/sh
  python manage.py syncdb --noinput
  python manage.py migrate --noinput
post_static_script:
type: string
default: |
  #!/bin/sh
  python manage.py collectstatic -v 0 --noinput

Note that this is not making unanimity so far.
There is several reasons that makes the scripts approach tricky:

* You don't want to execute these scripts every time a little detail change.
* You might need the database configuration to be ready for some script.
* You could be not using south
* You might want to import some initial data and maybe only once at install 
time.
* You could want to compress static files after running collectstatic
* etc

An other idea could be to use a Fabric plug-in that use Juju's database to 
connect
to the machines and run commands like this for example::

  fab -R my_django_site python manage.py pull

would pull the latest version of the site and reload the application on 
every
deployed Django machines.

The bottom line here is that it's not simple to find out what a standard
Django deployment (and is maintenance) looks like.

That being said, I'm really looking forwards for you comments and 
suggestions.

Patrick

  Hi Tom :

  I would like to try out your recipe this weekend and I hope that
  you might be around to answer further questions. But first I will
  answer yours:

  FYI: I have been a pythonist for 10 years and a web programmer for
  17, but I have always worked in straight CGI, so this is new
  territory for me.

  At this time, I don't have a target for a django app, I am just in
  get-acquainted mode. If I test a django app on a remote server, it
  will be one hosted on hostmonster. Hostmonster does not provide
  mod_wsgi as I understand it.

  On down the road, I can foresee doing django projects on a
  non-shared server where I have full control over what I enable on
  apache and I am clear that in that case, wsgi will be the best
  choice.

  As for my mac :: unfortunately, I am kind of new to mac also,
  having used linux for the 12 years previous to getting this mac.
  Enabling fastcgi on my mac's apache had all kinds of problems, of
  which I don't at this time have time to elaborate on or to solve -
  although I am sure that is forthcoming. (some time)

  I hope that I can use your recipes as a talking point, and ask
  some further questions of you. Perhaps it is best that we
  'reboot' under a different thread subject - as in 'fastcgi
  recipe' and the generated content might be of some help to others
  as well.

  Thank you for your reply. I'm going to owe you a beer when this is
  all said and one.
  regards

Re: Converting Django app into a Desktop app

[Czarek Tomczak]

Hi Loai,

Have a look at CEF Python that embeds Chrome browser:
https://code.google.com/p/cefpython/
You will need to run a web server to convert it into a desktop application, 
have a look
at CefBottleDesktop  that 
embeds CEF and runs a python web server along with
bottle.py  framework.

Also have a look at Python Desktop that embeds Internet Explorer browser and
Mongoose web server:
https://code.google.com/p/phpdesktop/wiki/EmbeddingOtherScriptingLanguages

I am the author of both projects.

Cheers,
Czarek.
