Django & subprocess

[malinoff]

Hi all, please, i need your help.

I use suprocess module, executing 'stockfish' uci engine, like: engine = 
subprocess.Popen('stockfish', stdin=subprocess.PIPE, stdout=subprocess.PIPE)

My module use opened subprocess receiving some information from Django's 
form, for example - move like 'e2e4'

I use sessions to save information about engine and chess table, so, when 
the page is loading the first time, my engine works properly - it draws 
chesstable on the page and so on, using engine.stdin.write() method.

But when i use form to send user's move to the engine, Django says: I/O 
operation on closed file - right on the engine.stdin.write() line, and it 
seems that PIPEs were closed, but WHEN they were, i cant catch.

Can someone help me?

force_text did not exist in 1.1, but it exists in current master. Getting
an error referring to it rather implies that you're running a mutant
version with some leftover py/pyc files form when you were running current
master (which appears to be what you were running for the first traceback
posted -- the " __init__() keywords must be strings" error there is what
you get today on master if you run with Python earlier than 2.6.5).

I'd start over with a completely new install, in a completely new directory
tree. (I also would not include "django-trunk" in the name of that tree, if
it was actually intended to hold 1.1.something.)

sorl-thumbnail or easy-thumbnail

[galgal]

What image engine to choose sorl-thumbnail or easy-thumbnail? I saw on 
github, that easy-thumbanil is still updates, and sorl last update is about 
5 months ago.
I use sorl for a while but want to try something else. Does easy-thumbnail 
work in admin when image are displayed? sorl has a special admin class - i 
haven't found it about easy-thumbnail

django.contrib.markup deprecated in 1.5 - what's the alternative?

[Phil Gyford]

I noticed that django.contrib.markup is marked as deprecated in Django
1.5 . If
I'm starting a new project now, what alternative should I be using, to
avoid running into problems with future versions of Django? I could
write my own Markdown (or whatever) filter, but I wondered if there
was going to be a standard replacement built-in?

For bonus points - why are those filters being deprecated?

Re: django.contrib.markup deprecated in 1.5 - what's the alternative?

[Jirka Vejrazka]

Hi Phil,

  incidentally, I was looking at this just recently. The
contrib.markup was deprecated mainly due to security issues with 3rd
party libraries that could not be fixed in Django itself and were
compromising its security. For more, read
https://code.djangoproject.com/ticket/18054

  Can't tell you what the replacement is. I rolled up my own markup
filter, but I only have a handful of trusted users for my web app so I
don't have to be too concerned with trusting their inputs.

  You can copy the markup filter from 1.4 - just be aware of the
security consequences.

  HTH

Re: tree.io installation with django

[Fabian Weiss]

I do so! I tried now this one: 
http://blog.stannard.net.au/2010/12/11/installing-django-with-apache-and-mod_wsgi-on-ubuntu-10-04/
And it works! :) 
http://project.immersight.de/

I tried again all I could find in the net for treeio, but nothing works :(
How can I totally remove all my steps? Is it just to delete the 
directories? Or is there something to do in a database?

Maybe I have a version of django which is too new? It is 1.4.1

Why don't you use django 1.3 as it is described in the requirements file?
Thats a simple way to see if you problems stem from django version
incompatibility

Re: Django sms

[Lunga Baliwe]

Thanks Dennis,

I'm kind of newbie to software,  but now I have an idea of what I need to 
do because two of cellphone service providers in South Africa(Vodacom and 
MTN - thanks for the list) do support email2sms.
I now have an idea of what I need to do, if I end up using the Django-sms 
app, I will post back.

The website will send sms' to a group of people who are members of an 
organisation informing them of meetings and other group announcements.

Thanks for the clear explanation and for your help.

Django, how to automatically sort the database's entries when I add an entry?

[Nicolas Dubien]

Hi,

I'm using a quite huge database with twenty thousand entries or more. At 
the beginning, I used to sort it each time (.sort_by("my_field_name")) I 
need the page but I saw that it took me lot of time to generate the page.

I'm looking for a solution, that allows me to show the data without sorting 
it each time I want to see it. For a instance, sorting the database each 
time I add an entry or each time I add several entries could be a solution.
Is it possible to keep the database sorted by a field without changing the 
pk?

I tried the class Meta with the argument ordering but it didn't work (even 
if I flush the db).

Yours,
-DubZzz

Newbie, trying [read: failing] to set up Django

[Helly]

Hello all,

I've been trying to set up Django for quite some time now. I'm on Mac OS X 
Lion 10.7.4. As to my level of expertise, let's just say I'm pretty new 
to...computers. I guess I figured I'd just stumble around until it worked. 
How hard could it be right? Wrong. It seems like you all don't mind helping 
out newbies though, so I thought I'd give this a shot.

I'm running into problems with synchronizing Django with my database. I 
installed MySQL and MySQLdb. I created a database and edited the 
settings.py file according to instructions in the tutorial. However, I 
couldn't get it to work with the python manage.py syncdb command due to an 
"architecture" error. Keep in mind that I had, at this point, spent a 
really long time trying to set these babies up, and this is what finally 
stumped me.

So, I told MySQL and MySQLdb that I was taking my ball home if that's how 
they wanted to play. I downloaded and installed Homebrew, Macports, and 
postgreSQL (through Homebrew) with minimal fumbling. There was one error 
with my PATH but I fixed it in my .bash_profile. As per the advice of the 
internet and Homebrew's brew doctor, I amended "PATH so that 
/usr/local/bin occurs before /usr/bin." This allowed me to start up psql 
and create a database - at least it seemed like it worked, there was no 
satisfying little message about its dimensions like in MySQL.

Anyhoo, now when I do python manage.py runserver or python manage.py syncdb 
it tells me lots of stuff and "ImportError: No module named 
psycopg2.extensions." What does this mean, and how do I fix it? I am 
totally at a loss.

I'm sorry if the way I posed the question is long/confusing, but I wasn't 
really sure what information would be important. I can post the whole 
output from the terminal if it's helpful. It's really long though, and I 
had a hunch the last part is the important part. Any help would be greatly 
appreciated.

Thanks

Customizing the Django Admin Interface

[JJ Zolper]

Hello,

I was able to locate the Django files for the admin under contrib in the 
source. I was curious if I could get some tips about customizing the 
interface.

One website I read said I shouldn't change any of the Django source but if 
I want to set up a slightly different login page for example, to put the 
admin files in my local directories that I'm working with.

The real question is that I was able to edit some template files to change 
some of the wording displayed but when I tried to edit the CSS files to get 
a different design I did not see any changes when I restarted my server. Is 
there some sort of collectstatic command that needs to be run? Any input on 
how to propagate these CSS files through would be great.

Thanks,

JJ Zolper
