Re: Django Development environment

[Sam Walters]

Ok lets see. At the moment:

Editor:
vim + http://code.google.com/p/trespams-vim/
sometimes gedit or kate

Editor console *this has been really useful:
yakuake

Debug client-side:
firebug, yslow, a windows computer with ie7

Version system:
git

OS:
develop on apto-sid (debian unstable), deploy on debian or some sort
of redhat style os.

DB (depends on project):
mysql, postgres+spatial, sql-lite

Webserver:
apache 1.3, apache 2.2, nginx

Method of deployment:
Fcgi or wsgi

VIrtualisation:
vserver guests

Its not perfect but iv'e got used it.
Also lots of different extras i put into projects like south or
reverse-select, jinja but that depends on the project.

Interestingly on the three GUI systems i use kde, xfce and gnome as
most of my stuff is done in yakuake.

cheers

Just for your info.

Forcing the import of 'settings.py' with the two lines, that I suggested
might be required in case, that your module might be
THE module using as very first module settings.py.

This is probaly NEVER the case when running in a 'normal' environment.

However for debugging I import  some of my modules from a command line
script, which just sets
sys.path and
os.environ['DJANGO_SETTINGS_MODULE']

In this case you had to force the evaluation of settings.py before
creating a logger.

 you had to be sure, that the django settings and thus the logging
 configuration has really been completed.

 You could for example add following two lines before:

> LOGGING = settings.LOGGING # force import

 The second line is needed, as the first line is a 'lazy import' and will
 only read the settings and configure logging  when you access the first
 time a element of settings.
 I just used settings.LOGGING, as it should always exist, when you try to
 log.

Okay.. update.. it does seem to work right, even without forcing the

(maybe Django 1.3 doesn't require the settings.LOGGING?)  While testing with

Re: ipython 0.11 with django 1.3 /in virtualenv

Apologies. I think I didn't express myself well enough.
ipython is being used bydjango.

What I just don't understand is why ipython does not import my
customisations if called via './manage.py shell'?

What I wanted to do is configuring ipython such, that it imports already
some of my application libraries when starting the shell.

This would accelerate my debugging activities.


With older versions of ipython Imanaged to do this via some code in
ipythonrc.

However since ipython 0.11 the way, that once customizes iptyhon has
changed.

Now I have to some python files like
~/.config/ipython/profile_default/ipython_config.py,
which seem to be loaded when running ipython,
but which don't seem to be loaded when running ./manage.py shell

I have two different ipython versions on my system:
an older one installed by my distro
and 0.11 in the same virtualenv in which I installed django.

I am rather sure though, that ./manage.py shell picks up the correct one.

If I type
dir()
in ipython, then I see the symbol 'get_ipython' which does not exist in
my old ipython version.

Yes I mentioned it in the title just in case.

why is settings.py executed twice?

[Gelonida N]

Hi,

This is also one of the things (I just started using django, so I have
still quite many questions) , that I don't really understand.

It doesn't break anything and I am not stuck.
I'd just like to understand.



$ django-admin startproject settings_twice
$ echo 'print "SOMETEXT"' >> settings.py
$ ./manage.py shell

The output, that I get is
SOMETEXT
SOMETEXT

In [1]:


So it seems settings.py is executed twice.

I would have expected, that settings.py is imported multiple times.
What I thought though is, that a module is normally only executed once
during the first import
and that subsequent imports do not execute settings.py anymore.

It seems even, that all modules imported by settings.py are executed twice.

Is ./manage.py shell starting two processes??

If yes, why wasn't settings.py imported before 'forking' ?

Thanks a lot in advance

Re: ipython 0.11 with django 1.3 /in virtualenv

[Shawn Milochik]

If iPython is installed it should be used automatically in Django's 
manage.py shell.


If it's not working and works when you run iPython directly, the most 
likely case is that you're running two different Python environments and 
one has iPython installed and the other doesn't.


You mention virtualenv in the subject line but not in the question. Try 
running 'pip install ipython' in your virtualenv.

ipython 0.11 with django 1.3 /in virtualenv

[Gelonida N]

Hi,


I am having issues with ipythin when I run

./manage.py shell
then ipython_config.py doesn't seem to be executed.

On the other hand if I run ipython directly the file is imported.

Am I missing something?


My setup:

$ find ~/.config/ipython/
/home/gelonida/.config/ipython/
/home/gelonida/.config/ipython/profile_default
/home/gelonida/.config/ipython/profile_default/log
/home/gelonida/.config/ipython/profile_default/ipython_config.py
/home/gelonida/.config/ipython/profile_default/history.sqlite
/home/gelonida/.config/ipython/profile_default/security
/home/gelonida/.config/ipython/profile_default/pid
/home/gelonida/.config/ipython/profile_default/db
/home/gelonida/.config/ipython/profile_default/db/dhist
/home/gelonida/.config/ipython/README

The contents of
/home/gelonida/.config/ipython/profile_default/ipython_config.py

The first few lines are:
import time
print (("HELLO "*17)+"\n") * 20
time.sleep(2)

I added the sleep statement in case, that the print statement woudl have
been overwritten.

If I start ipython,
then I see the HELLO text and a delay of 2 seconds happens


with

./manage.py shell

I don't see the output.

I n order to be sure, that there's nothing weird in my django project I
tested this also with an unmodified django project, which I just created
with.

In order to reproduce just run once
create a
~/.config/ipython/profile_default/ipython_config.py
with a print statement

and start
ipython
# here you should see print statements of ./manage.py shell


then do:


django-admin startproject tstipython
cd tstipython
./manage.py shell
# here you do not see print statements of ./manage.py shell

Thanks in advance for any explanations.
I would really like to understand what exactly happens.

That's weird.
This works fine for me.


Just some more things to test:


Is ee, that you didn't add a root logger in your
log config.

you could add following two handlers.


'loggers': {
# root loggers
'': {
'handlers': ['console'],
'level': 'WARNING', # or 'DEBUG'
'propagate': True,
},
# not sure if this is really useful
'root': {
'handlers': ['console'],
'level': 'WARNING', # or 'DEBUG'
'propagate': True,
},



If this doesn't help you could add some print statements to be sure,
that your settings file is really read.



You could add a print statement after  the assignment of
LOGGING in settings.py

LOGGING={ .. ..}
print "LOGGING VARIABLE IS SET NOW"



and in your file.

print "CHECKPOINT 1"
from django.conf import settings
print "CHECKPOINT 2"
LOGGING = settings.LOGGING # force import
print "CHECKPOINT 3"
import logging
logger = logging.getLogger('otherlogger')
print "CHECKPOINT 4"
logger.warn('hello')
print "CHECKPOINT 5"

What do you get as output?

Re: Combining queries? A "join" in Python?

[Matteius]

Since you are combining two sets of different objects you'll want
Gelonida's response.  Additionally, Use Q to create more logically
advanced queries.  I find your language difficult to gather what query
you are looking for exactly, but here is an example of what I think
you might mean:

from django.db.models import Q

the_Ds = D.objects.all().filter(b=B)
the_Es = E.objects.all().filter(c=C)

combined = the_Ds | the_Es

# Other Example (an & requires both constraints to be met, and an Or
will include the set of all matches.
the_As = A.objects.all().filter(Q(constraint1) & Q(constraint2))
the_Bs = B.objects.all().filter(Q(constraint1) | Q(constraint2))

-Matteius

Don't overlook how powerful this is because Django has Manager classes
so you can make your constraints refer to both local properties and
foreign key constraints as well as properties within the foreign key
lookups.  You may find that you wish to edit your schema relationship,
perhaps by pointing backwards or reversing the relationship.  It is
hard to say with the categorical A, B, C, D example, but hope this
helps and Good Luck!

Thanks Gelonida.. tried your suggestion and added those two lines before my

@Reinout: Thanks, but yeah, already tried logging from a view function..
didn't work...

@Bruno: Yeah, I am using the dev server.  I have been using from django.conf
import settings within my app to access settings..although unless I do
something like what Gelondia suggested... with the LOGGING =
settings.LOGGING, I'm not sure how the logging normally "invokes" the
settings.  The way I see it, django magically loads the settings at some
point in the background, then when you use the logging, it accesses those
settings, and there's a certain time when these settings become accessible
so this works.  But it's not working like this, so perhaps I'm mistaken.  So
you're saying to replace all instances of "from django.conf import settings"
with just "import settings"?  Or the other way around?  Not sure about what
importing only twice does, and how importing settings more or less affects
this.

Thanks all for answering.

Re: Possible interest in a webcast/presentation about Django site with 40mil+ rows of data??

[Cal Leeming [Simplicity Media Ltd]]

Bloody thing, had to send it directly to the list cos it doesn't have the
option of bulk inviting people. How annoying :X

Anyone who didn't receive the invite email, please let me know.

 Hi all,

 Okay, good news and bad news.

 The bad news, is that the site/project which sparked this webcast to be
 made, has had some legal complications and is being shut down - less than 1
 month after being released :L

 The good news, is that the webcast will still be going ahead.

 For those of you that want to see the site it was related to, it's
 http://www.iliketochan.com .

 The site itself was a complete 4chan archive, dating back to 2010,
 peaking at 50 million posts and 17 million images.

 Particularly sad about this because so much time and effort went into
 the site, but at the same time, it has been a great learning experience
 (both in code and business). So being able to share that on the webcast 
 will
 be of some small comfort :)

 Hi all,

 Great response to this, 45 registered votes in total.

 The webcast will take place on Monday 29th August 2011 - (Minimum
 resolution 1920x1080)

 However, because the time zone results are almost split 50/50, I'm
 going to allow users to select from two time slots, if the results are 
 still
 split 50/50, then I'll do both an afternoon and evening session.

 Please use this form to register your place.

You can 'or' two query sets with the '|' operator


so do
queryset1 = Mymodel.objects.all().filter(...)
qyeryset2 = Mymodel.objects.all().filter(...)

combined = queryset1 | queryset2

Right, sorry that's what I was going for but I brain spasm'd on the iPhone. 
Bitbucket has gotten a lot better since Atlassian took it over.

Django 1.2 never did automatic serving of media_url, you always had to
configure that manually if you wanted it.

Correct. Although Bitbucket offers unlimited private repos. It just limits you

Kenneth,

I think he means whether or not the repository will be public or private. 
Github (git) does not offer private repos unless you pay whereas bitbucket 
(mercurial) gives you 5 private ones for free as well as the option for 
creating public ones. I personally am a big BitBucket fan as I find it much 
much easier to manage and also a bit faster.

Ooops sorry sent my other request as a reply to this so sorry if it screws up 
this thread.

As for how much memory you need for memcached that is something that is highly 
site dependant. Some sites can manage with a relatively low amount of RAM 
dedicated to memcache as they don't have a whole lot of data that needs to be 
cached at any one time. Others require huge amounts.

I would suggest you do some experimentation and see what the effect on your 
server load as you play around with memory amounts.

Historical Djangocon videos available for download in iTunes?

[Simon Connah]

Does anyone know of a source for previous Djangocon (both US and EU) videos 
that allow you to download them in iTunes? So far I've only seen them available 
on the schedule page of the EU Djangocon site and on Blip.tv. While I can 
certainly watch them there I prefer to have them on my hard drive for easy 
reference at a later date.

Thanks for any help.

Combining queries? A "join" in Python?

[graeme]

I have a some models related link this:

A has a foreign key on B which has a foreign key on C

I also have D with a foreign key on B, and E with a foreign key of C

If I do A.filter(**args).select_related() I will get all the As, Bs,
and Cs I want.

How do I get the Ds with a foreign key on a B in my queryset
(preferably filtered) and all Es with a foreign key on C (also
preferably filtered)

The best I have been able to come up with is to query for all the  the
Ds and Es I want, and combine them with the Bs and Cs in the view.

I have a similar problem with another site, except that there not
every B I want has an A with a foreignkey pointing to it, so I cannot
just do select_related on A.

I am not worried about doing an extra query or two per page. What I
want to avoid is doing an extra query for each object in a lengthy
list.

Re: Installation

[Babatunde Akinyanmi]

Hi Prem,
You said your django is located in a folder named Django-1.0.4. That
is where your PYTHONPATH should be set to not Django-1.3. Since you
had multiple python installations, make sure that windows associates
.py files with Python 2.7 and not Python 3.
If it still doesn't work, you can try this though its not a very
elegant solution. Copy the django-admin.py file from wherever your
django installation is into the directory you call the django-admin
command from
