It's generally considered polite to wait a bit more than 16 hours before
posting a "hurry up" repost when nobody has responded.

There is no core Django support for translating content stored in the
database. Do a google search for django-multilingual for one
alternative.

my database was unicode from the begining. After upgrading to the  
unicode revision, many (not all) non-ascii characters stopped  
rendering properly. They would render on the web page, but not on the  
admin pages. This was in finnish, particularly the letter ä. We had  
to re enter all the data that had these characters. The same problem  
happened for a set of polish sites - here there was a huge amount of  
data, so the owner shifted from postgres to sqllite to solve the  
problem. I have some sites in Indian languages which were not  
affected however.

Re: static images with built-in django server

[girzel]

Me too, I can't get this to work and it's driving me crazy. My main
problem seems to be that Django is looking inside the Django site
package within my Python framework for the media (when I try to load
an image directly, for instance, it tells me "Page not found: /Library/
Frameworks/Python.framework/Versions/2.5/lib/python2.5/site-packages/
django/contrib/admin/media/img/image.gif") and I don't know how to
tell it to look in my site installation instead of python.

I'm using Python 2.5, Mac OSX, the svn version of Django, my
development server runs at http://127.0.0.1:8000/

In template I've tried:
http://127.0.0.1:8000/media/img/image.gif";>
and


In the site package urls I've got:
(r'^media/(?P.*)$', 'django.views.static.serve',
{'document_root': 'media'})
I also tried writing out document_root as the full absolute path to
the media directory on my computer.

MEDIA_ROOT = './media/' (relative path from settings.py, I also tried
a full absolute path)
MEDIA_URL = 'media/'

for completeness' sake, the absolute path to my media folder ought to
be /Users//Documents/Django//media/

I tried all the above in various configurations. It's voodoo at this
point and the gods are not smiling. If anyone can see what my problem
is I'd be very grateful for a pointer...

Thanks,
Eric

That sounds rather worrying, from someone who has a big database and
will soon be upgrading to unicode django.  Do you have any more
details?  Was it simply due to a database encoding change (in which
case databases which are already in utf-8 should be ok?), or did you

Re: Scaling the server

[simonbun]

> Well, I have another server available now ;)

And you're using it for serving static content I hope? Your previous
setup with Apache serving everything with KeepAlive off can bring many
a server to its knees. If you serve a html page with for example 30
css, js and image files, you make a single request that needs 31 free
Apache processes. This will usually mean spawning quite a bit of extra
processes, which is somewhat costly in terms of CPU usage. On top of
that, all of those processes load all enabled Apache libraries and
usually end up consuming quite a bit of memory (especially with
mod_python as a static module).

I think you'll see a great performance boost if you let Lighttpd or
Nginx handle your static files. In which case (and imho only case) you
can have Apache's KeepAlive set to off.

In fact, I don't think you absolutely need a second physical server
for serving the static content. Unless serving files is quite a big
part of your operation of course. Do some stress tests with Lighttpd
or Nginx running alongside Apache and see how the server holds out.

Simon

authentication on generic views

[Mike Maravillo]

Hi,

I'm using the django.views.generic.list_detail.object_list generic view
because of the handy pagination.  However, I need to have the user
accessing the page to be authenticated first.  Is there any other way
than doing the check on the template?  Thanks very much.

Re: elance'in django programmers

Well the more skills you have as a programmer... the more work is
available to you... but also the more skills you have...the more you
expect to be paid.

Someone that knows only PHP ... or only knows Flash Actionscript,
etc shouldn't expect to get paid as much as a developer who is
knowledgeable in many languages.  Similarly, a newbie programmer with
only a few months experience, or no 'professional' experience,
shouldn't expect to be paid the same as a developer with many years of
software/web application development experience under their belt.

Re: elance'in django programmers

Speaking as someone who's tried their hand at both sides of the coin,
I definitely agree with you, Ross. I'm currently employed, but when I
was trying to make it as a contractor (because a job fell through), I
couldn't land a single job because of the market dillution. Working in
PHP as I was, I found that I was competing against high school and
college students, whose bills are paid by their parents, and can
afford to spend weeks on end getting paid next to nothing. And yes,
the quality of their work showed.

The trouble with most good developers is that they're not willing to
work for cheap change. And it often has little to do with getting paid
appropriately for their skill level. For me, and many others, the high
price is necessary because we have families and mortgages to support.
Contracting for a low price is only good for a certain type of people,
and that pool doesn't contain very many quality developers.

Just keep in mind that contractors don't have an endless pool of jobs
to choose from, where they can just pick whatever price they feel
like. They have to make sure that each job can sustain them until they
secure another job. It's not a fun way to live unless you're already
very well established.

Are you using mod_python to host Django? If so, you may be hitting
mod_python bug described in:

  https://issues.apache.org/jira/browse/MODPYTHON-240

Although not sure why you are getting 404 unless your Apache can't
find its standard 500 error document or something and is then trying
to raise a 404 error for it.

If you are using mod_python, you might look at mod_wsgi instead as it

Basic User-Admin Questions

[Adam D.]

I am building a site in which there are many users, who will have
there own mini-site, where they can manage contacts, todo lists, etc.

The django admin interface is used to administer the 'entire' site. So
I assume there wouldn't be many 'user-admin' implementations. How
would I create a user-admin section for each user that would need
basic features such as...

I essentially don't need the super-user admin, I need many user
account admins, at the user level.

User Logs In >User has several options (apps) > User can manage a ToDo
list (CRUD) and manage there account settings, etc.

I know these thoughts are farely fragmented. I hope this makes sense...

Re: How to let some users manage other users

[[EMAIL PROTECTED]]

> The  problem is then that I want some users to be able to create new accounts,

If you're trying to do it through the admin app, you'll probably not
be able to pull if off since the admin doesn't have row-level
permissions.

Are you looking at using the Users model from the auth app? If so, I'd
suggest looking at the Groups app with it. I'd probably create a
special page (login_required) that would allow that parent user to add/
edit/delete users in their own group. This would keep "bar"'s accounts
from modify "foo"'s. This would also let you get an even finger-
grained control and only let users edit accounts they have created.

The execution might be a little tricky; you'll probably need to use a
user profile model to attach the extra metadata to a user w/o
modifying Django's contrib auth app. (Editing core is the path to
darkness for me) This way you could assign the necessary extra data to
a user - what user created them, if it is a "parent" account, etc. It
won't be hard, but the devil is in the details of setting up the user
profile models. James Bennett has done some great work in this area
that you might want to check out. (look at b-list.org)

This may not be the best approach, but it's the first to come to mind.
I hope this helps.

Re: How would you cache a view that will never change?

[[EMAIL PROTECTED]]

> change depending on a request on my application?

Is the output something difficult for the view to generate? If not,
you could just specify a very long cache expiration and let it
regenerate itself as needed. If you're using memcached, it's going to
be stored in RAM and is subject to being wiped out if the process
restarts, so you really can't rely on  it being there. If it is an
expensive view to process, the next request after the cache expiry
would be an unlucky visitor; this may not be a great option in that
case.

If you *really* need it to write once, you could write a couple of
methods that will write and load the output to/from the file system.
At the beginning of your view, you could use the getter method to look
on the filesystem for the file the same way the cache api does a
lookup. (Keep in mind that filesystem lookups are going to incur more
I/O latency than Memcached)

FWIW, If you do follow this route, I'd suggest putting the filesystem
path in your settings file to make the application more portable.

Hope this helps.

In case anyone is having the same problem, it appears that my 91 and
97 sites both using Psycopg in the same Apache process didn't like
each other. When I changed the 97 site to use Psycopg2, I could not
reproduce the problem.

This sure isn't a definitive answer, but it's a step in the right

Have you tried giving the user superuser status to see if that works?
This might help narrow it down.

Have you tried going through the shell and seeing if it sees the
permissions?

i.e.

>>> from django.contrib.auth.models import User
>>> u = User.objects.get(username__exact='username')
>>> u.user_permissions.all()

Re: Python 2.5, Postgres, Psycopg2 on OS X

[Kristinn Örn Sigurðsson]

Sorry if I wasn't clear about what I was talking about. :-)
I'm using Darwin ports. They work similar to BSD ports (completely different
but the idea is probably from there). With that you can install alot of *nix
applications. The homepage for Darwin ports is http://darwinports.com/.
Darwin ports installs everything to a new location, /opt/local, so it won't
interrupt the base MacOSX system. Fink which is an apt-get workalike is also
a good package manager. You can probably install everything from there as
well. Fink installs everything under /sw (you can change it).

I installed postgresql, psycopg, and python through Darwin ports. The only
thing I need to do to make the system use python from Darwin ports over the
MacOSX version of python is by putting /opt/local/bin and /opt/local/sbin
before /usr/bin and /usr/sbin in the PATH variable in my .profile (for my
shell environment). This is very handy, now I will never have problems
updating python, postgresql and psycopg because I can update all installed
applications (from Darwin ports) with one command. Everything worked fine
after I installed those things. The only thing I had to do was to get the
svn version of Django and it just worked. :-)

Hope this helps.

Kristinn.

How would you cache a view that will never change?

[Kai Kuehne]

Hi list,
maybe I'm a bit confused (or tired) but
how would you go and cache a view that will *never*
change depending on a request on my application?

If I read the manual right, I have to give a timeout to
all the cache functions that are available. In my case I have
a view that will never change... so I don't really
know how to do this.

I think I'd need something like caches_page like
in rails where it generates an html file and stays
there *till* I explicitly say it can be removed.

Has anybody of you built something similar for django?
Thanks for help!

Re: Python 2.5, Postgres, Psycopg2 on OS X

[Matthew Wensin]

Can you elaborate on “just install and update your python version through
ports and install everything you need from there”?

I’m using Python 2.5 (from here: http://pythonmac.org/packages/)--do you
mean Python 2.5.1?

LimitRequestBody 102400

[Roboto]

Hi All,

I'm trying to stop people from uploading like 3mb images and crashing
the server.  I think, think, that to some degree my limiters are
working.  In my apache config I've set LimitRequestBody 307200.  That
should be about 300k.  Now when I upload an image greater than that, I
can see that Apache cuts it off somehow, and then I get a 404 error
page mixed in with a 500 error for some reason.

Is it working as intended?  How do I get control over what is occuring?

Re: Python 2.5, Postgres, Psycopg2 on OS X

[Kristinn Örn Sigurðsson]

That's too much of a hack when you can just install and update your python
version through ports and install everything you need from there, without
touching the MacOSX system itself. I guess you can use /usr/local without
destroying the OSX, but still... I think the ports way is better. :-)
Just my 2 cents.

Re: Python 2.5, Postgres, Psycopg2 on OS X

[Matthew Wensin]

I've dealt with that exact error before, just yesterday, incidentally.  What
I did to fix:

$ locate libpq.5

If this returns nothing, try running:

$ sudo /usr/libexec/locate.updatedb

And then $ locate libpq.5 again.

Go to the directory containing libpq.5 (for me it was /usr/local/pgsql/lib,
and create a symlink called libpq.4.dylib to point to it, like so:

/usr/local/pgsql/lib username$ sudo ln -s libpq.5.0.dylib libpq.4.dylib

See if that helps.  Worked for me.

Re: Python 2.5, Postgres, Psycopg2 on OS X

I'm sorry. I'm using version 1 of psycopg. If I fire up a python shell I can
import it as "import psycopg". Hope that helps.

auto_now and auto_now_add *always* set the automatic value, they don't
supply default values you can override (this is documented).

If you want more fine-grained control, use the default attribute (which
you can also set to datetime.datetime.now) on the field.

The error is that it *only* supports Unicode string input and not
bytestrings, despite the internals appearing to be prepared to process
bytestrings (for example, he tries to trim Byte Order Marks, which don't
even appear when you convert  UTF-16 byestring to Unicode). Up until
recently, handled non-ASCII bytestrings, so considering this and the
code changes, it looks like an oversight that remains undiscovered
because of some subtleties in the markdown test suite.

If the markdown bug isn't fixed and the new versions will only accept
non-ASCII data as unicode strings, we'll change Django to work around
that, but for the moment I'm hoping the problem will be fixed in the
right place.

So you are saying that in an unknown collection of code changes that we
haven't seen, you are getting a very specific error message and you are
wondering if we can help debug it? Does it strike you that there might
be some information missing there for anybody to be able to help? :-)

Well, for a start, you should have any design discussion on django-dev,
instead of django-users. That's where development work takes place and
we try very hard to keep the two domains separate.

I think there's still some design work needed. For example, there's a
comment (#13) declaring that certain things were in and out of scope for
the ticket. However, I'm not sure that's a done deal, since it hasn't
been discussed anywhere. For example, work out how this might work
API-wise and then discuss it on django-dev to see if the same syntax
will work smoothly with, e.g., Oracle. You don't have to do the backend
work for Oracle, but having a public API that works well for the two
main systems that support schemas is really going to be a requirement
here.

So come up with an API, maybe even come up with a code patch --
particularly since you already have one, it seems -- and then start a
thread on django-dev to solicit opinions. My gut feeling is that it
won't be too controversial, but we should get the API "right", for th
reasons indicated above.

Re: elance'in django programmers

[Ross Poulton]

In my opinion, 40-50 Euros (Which is approx $60-$80 Australian
dollars, with which I'm much more familiar!) is a very reasonable rate
for a GOOD coder who does good design work along with their
programming.

The fact that you can get a PHP coder for $20 AUD/hr probably says
more about the dilution of coders and the quest by everybody to be a
paid PHP coder than anything else.

FWIW a salaried programmer in australia might be on about $30-$40/hr,
a contractor probably in the realm of $80-$150 depending on the
client, the job, etc.

That said, if elance is anything like rentacoder, I'd expect people
promising the world for very little cash - people who quote $100 for a
50 hour project are obviously not going to give as good results as
somebody who quotes $2000 for the same job.

Re: elance'in django programmers

[Roboto]

lol
Well 40-50 euros is definitely a number I didn't expect.  I live in
Canada, and on the net freelance work goes for about 20 CAD/hr, say
for a PHP dev or something.  It's alright, it's about how much we pay
programmers here generally speaking.  But at a rate of 100 CAD/hr... I
wouldn't mind putting down the money as long as there was a way to
prove that he could produce the same amount of work as a PHP developer
in 5 hrs - or if his work was that much more superior than anyone
elses (excellent html, css skills /w django)

Which I don't doubt, there are definitely some instances where I've
found Django to be much >> PHP.  But then again, it was more of a
function of the language.

Running prefork I see. What I would suggest is on a separate box build
up Apache with worker MPM and test your application thoroughly on it
instead and see if it works. Although the guidance for Django is to
use prefork and Django wasn't originally designed with multithreading
in mind, there is currently no known problems with it running on
multithreaded worker MPM and many people do just this. You obviously
though need to confirm that your application layer is itself
multithread safe first though.

By using worker MPM instead of prefork MPM, you will immediately be
able to drop the number of Apache child processes in use to a much
lower number. This will drop back overall memory use significantly. If
you are running into problems with memory swapping, this would help
greatly to avoid that.

Whoops, had a brain fade. Meant MaxRequestsPerChild which you do have
set. The thread variant of that is BEOS specific and doesn't apply.

Two other things to look at. First is you can run:

  vmstat 5

The si/so columns of that will show whether it is swapping.

The other thing is to run:

  netstat -a

This will show state of active socket connections, one possibility is
you are getting a lot of connections stuck in i/o wait type states and
running out of resources and/or Apache stuck waiting for old
connections to close down.

The ones above are simple ones to try, others may be able to suggest

Actually, it would be a fairly bad idea for the tutorial and would
actually *introduce* more mystery, on balance. Experience has shown that
a lot of people work through the tutorial before they have a completely
firm grasp on Python. Bringing up the subtle differences between class
and instance variables, which doesn't really affect how you use them at
all in any case, would be adding extra complexity where it adds no
value. If you have sufficient Python experience that you (a) notice this
right off the bat and (b) care about why, it's fairly easy to track down
by looking at the Model class or searching on Google. It just isn't
necessary to know this information to use Django and so it's not
appropriate for the initial tutorial.

You haven't made a convincing argument that this knowledge is required
to use the code or even makes it easier to use. Currently we say "define
these attribute and then assign to them and read from them". It can't
get much simpler than that in an introductory document.

There's a whole bunch of "what goes on under the covers" stuff that we
could write (in fact, the model initialisation process is documented in
the wiki -- see [1]). At the moment, we're focusing more on documenting
the public API, rather than the "how", since it's Python source code
after all -- if you care how things work, it's not too hard to just read
the source and grep around a bit.

Postgresql Schema Ticket #1051 - Trying to fix.

[Zenom]

OK so I am working on ticket # 1051 which is the PostgreSQL
search_path ticket. I checked out trunk today and made a diff. When I
go to the shell and create queries and save data it works like a
champ. When I try to run a test it gives me a
psycopg2.ProgrammingError saying that the schema doesn't exist.

What is confusing is that it errors out saying the 'andy' schema
doesn't exist, so it obviously knows what the schema name is. It's the
same one that works when I try to do normal queries.

Is there something else anyone can think of that I might need to
change for tests to work? This wont get submitted without a test and
well i can't submit if I cannot test.


On a side note, what kind of tests should I perform to help make sure
this gets accepted into Django. This is a very important piece for our
company and would like to see it as part of the base install.

You think that Unicode support is an error or i'm missing something?
This problem appeared because API changed in python-markdown and
django should support both versions for some time (checking python-
markdown version for ex.).

Re: management.call_command dumpdata does not return datastring

[Jacob Kaplan-Moss]

Hi Ulf --

The mangement modules are designed for use from the command-line, so
this is expected behavior. If you're looking to convert data into a
string, you'll want to use the serialization APIs directly, see
http://www.djangoproject.com/documentation/serialization/.

I'm a django developer in Argentina, if you earned 15 euro an hour, it

Re: write my own css

[[EMAIL PROTECTED]]

Hey,
  The admin media setting is only for django's admin interface.  For
me, I needed to change some things in the admin interface, and so
copied the media folder (in windows, found in "C:\Python25\Lib\site-
packages\django\contrib\admin\") to the root of my server directory
(alternatively, non-windows systems can use symlinks.) My settings.py
has the default:  ADMIN_MEDIA_PREFIX = '/media/'

  If you are doing doing something outside the admin interface, that's
a bit different.  I have a folder at /projectfolder/media with sub-
folders for css, images, etc., some of which have more sub-folders for
different applications.

 Settings.py has:  MEDIA_ROOT = 'pathtoproject/media/'
   MEDIA_URL = 'http://yoururl/media/'

 In my templates, to attach a css file I have something like:
{% block attach %}{% endblock %}

 I needed to add some stuff to my apache configuration to serve the
static files, and http://www.djangobook.com/en/beta/chapter21/ and
http://www.djangoproject.com/documentation/static_files/ were helpful
in how to do this.  The django dev server doesn't handle the static
files, but that's not a problem for me so I've not looked into if it
can or should.

  This works for me, hope it helps.

id is idle. That means the CPU is just sitting in idle state and not

The user docs don't need to explain *how* the magic is done, but it
would save a lot of head-scratching if they simply mentioned that a
small bit of magic is indeed being done.

The way it stands, a new user reads through the tutorial, starts
making things work, and then says, "wit just a minute
what's going on here? I've been referring to instance variables here
all along, but I defined them as class variables in my model. Did I
miss something somewhere?".

It would be trivial to just add a short sentence in the tutorial
saying something like, "Behind the scenes, Django sets things up such
that you automatically get instance variables for each of the class
variables you've set up.". Small price to pay for removing some
mystery, IMO.

How to let some users manage other users

[Kirk Strauser]

I need a little advice on how to approach a problem.  On our new website, we 
will create "parent accounts" for customers, and then let them create new 
logins for employees and contractors that they can customize in a bunch of 
different ways.  However, company "Foo" should not be able to see any of 
company "Bar"'s subaccounts or be able to manipulate them in any way.  The 
problem is then that I want some users to be able to create new accounts, 
but only see or edit accounts that they themselves have created.

If I were designing the whole site from bare metal with mod_python or PHP 
then I could imagine how I might do this, but I'd much rather work *with* 
Django than *against* it.  So, is there a Django-ish approach that anyone 
would recommend?

Re: crititcal tidbit of documentation missing (instance vs. class attributes)

[Dan Ellis]

Yeah, Django is doing some magic using a metaclass for Model
(ModelBase, which is badly named IMO, as it isn't Model's base class).
Most of the magic is in django.db.models.base.

The documentation tells you how to /use/ the model API, though. I
don't think there's any need for the docs to explain what magic is
being done; in fact, it would just be very confusing to most users.

management.call_command dumpdata does not return datastring

[Ulf Kronman]

Hi all,
I've been using the Django management module to output data from my
database in JSON format. This summer I asked some questions about the
changes in the call management.dump_data to
management.call_command('dumpdata',) and got good help and got it
working.

Now that I try to run my database management script again, I can't get
it to work. It outputs my JSON structure on screen, and won't return
data as a datastring to process.

This is how I used to do it before the change:
str_datadump = management.dump_data(['kth'], format='json', indent=2)

Then I changed to this:
str_datadump = management.call_command('dumpdata', str_application,
format='json', indent=2)

The result of the last line is a proper JSON output to the screen and
a str_datadump that is 'None'

Am I doing something wrong here? If I want to send the resulting JSON
data to a file, or capture it in a variable for further processing
before writing it to a file, what syntax should I use?

I am using the repository version of Django and am at revision: 6603

Regards,
Ulf

You don't need the ORM, so why not directly use some SQL?

from django.db import connection
cursor = connection.cursor()
cursor.execute...

You may lose database portability unless you are especially careful.

Thanks for the heads up. I hadn't even realized this option and have

Hi,

most people read the tutorial before reading db-api. But
you are right, it should be mentioned.

Re: Using edit_inline DateField is not showing up

[ZebZiggle]

I'm having the same/similar problem. I have a field

created = models.DateTimeField(auto_now_add = True)

which doesn't show up in the admin interface, but everything else
does ... including other datetime fields (just not auto_add_now).

The field exists in the database, is used and getting populated
correctly.

Strange.

crititcal tidbit of documentation missing (instance vs. class attributes)

[bramble]

It looks to me that even though you set up class attributes in your
models, when you *use* your models in your code, you access them as if
they were instance attributes.

Nowhere in the tutorials or the model or db-api docs is this
mentioned.

Unless I'm misunderstanding it, evidently, Django is doing some magic
here for the user and it probably should be mentioned in the docs.

Not all the time, once I have 4GB of ram the server don´t go to swap
almost all the time. I can´t tell preciselly if the server is onto
swapping when the server stucks. I will pay attention to this when the
problem occours again. I´m not a server expert, is this top output

I don´t have any performance meter, I thinking on put a script making

recommends me any performance test tool?

I can´t tell preciselly but I think apache is the bad guy here.
Yesterday, my server start to have problems just after I change a
header file used on partnets sites. The header is an static file, it
seems that when many users start to download the new header (the older
was cached on client), my site start to be slow until stuck.

I see your posts ;), I can give it a try. But I want to fight the real

When you set up the queryset initially, it doesn't actually hit the
database yet. So your "result" variable doesn't contain any objects,
it just contains instructions on how to get the objects.

Instead, you're actually executing the query when you use results[0].
This hits the database, gathers the results into a temporary list, and
returns the first item in that list. Since you didn't assign that list
anywhere, Python (and thus, Django) has no way of knowing that it
should reuse it.

So when you use results[0] again, Django hits the database a second
time, getting you a fresh copy of the object, as it appears in the
database. That means it doesn't have the modification you made to the
first object, so when you save it, you'll notice that nothing changes
in the database.

So, in a nutshell, you're altering the name on object 1, but saving
object 2, which was never modified. Assigning results[0].user to a
variable makes sure that you're using the same object each time,
without hitting the database and getting multiple copies.

I don't know if I made that very clear, but if I didn't, I'm sure
somebody else here can explain it better. Hope this helps!

Help understanding the DB API

Problem with django captcha module

[BitBlazer]

Hi,

I just tried the django captcha module in my application. Everything
is fine except for one small problem. The code that extracts the font
files from `fonts` directory doesn't pay attention to the hidden
files. For example all my code is in SVN. As a result each project
folder has a hidden .svn folder. The code for extracting the files
from fonts directory directly uses the listdir() function without
bothering about hidden files (.svn in my case). As a result the
listing of font files also includes an erroneous font entry with the
name `path/to/fonts/dir/.svn` which raises IOError when used (which
happens randomly). Even though I have fixed this problem in my case
but I guess there should be a proper solution for same.

Cheers!
BitBlazer
