Create files and directories from Django 1.2.1
Hi all, I recently migrated from Django 1.1.1 to 1.2.1. In 1.1.1 I had an application which imports an external python script in which a directory and some files are created. Since the migrate this doesn't work anymore, I get a number of IOErrors because the files (and directory) that should be created can't be found. I've tried changing my directories and slashes (I'm using Windows), but no success. Can't I use the os python functions anymore in Django 1.2.1? In the documentation I've read about Managing files in models but I prefer to handle this through my external script. I hope anybody can help me.

Re: Create files and directories from Django 1.2.1
Hi Mike,
Thanks for your reply. I haven't changed anything else, I am
processing the MS updates, but I don't think this is the problem, as
this all worked fine before the migration to 1.2.1, also if I call the
script directly (outside Django) it works fine.
My view looks like this:
..
import createKML
..
def my_view(request, arg):
...
createKML.createKML(arg)
...
In the createKML.py the problem arises in:
...
import os
...
def createKML(id):
...
os.mkdir("D:/path/to/mysite/templates/maps/"+str(id))
writefile = "D:/path/to/mysite/templates/maps/"+str(id)+"/"+str(id)
+ ".kml"
f = open(writefile, 'wb')
...
I hope this helps?

Re: Create files and directories from Django 1.2.1
Allright I tried a couple of things with your suggested appraoch:
- I printed all the strings used to define paths and files, this all
seems correct.
- The os.mkdir() command is passed without raising an error, but
without creating the directory either, this results in an "IOError: No
such file or directory" because of course a file can't be created in a
non-existing directory.
- I tried creating files in different already existing directories and
this works as expected.
- I tried to use os.makedirs() instead of os.mkdir(), this raises an
interesting error: "mkdir() takes exactly 1 argument (2 given)", I
tried calling the script outside of Django and this should work the
way I'm using it:
kmlpath = "%s/%s" % (basepath, game_id)
if not os.path.isdir(kmlpath):
os.makedirs(kmlpath)
- I tried creating a file without any directory structure in the path,
the file is created in the root of the website, if I try creating a
directory with os.mkdir() it should take the root as well I presume,
but no directory is created.
It seems that Django 1.2.1 has problems calling the os.mkdir() and
makedirs() commands ?

Re: Create files and directories from Django 1.2.1
Hi Doug,
Thanks for your reply. I tried your suggestion:
..
import createKML
..
def createKML(id, basepath=os.getcwd()):
...
try:
kmlpath = os.path.join(basepath, "templates")
kmlpath = os.path.join(kmlpath, "maps")
kmlpath = os.path.join(kmlpath, str(id))
if not os.path.isdir(kmlpath):
os.mkdir(kmlpath)
writefile = os.path.join(kmlpath, (str(id)+".kml"))
except Exception as e:
...
f = open(writefile, 'wb')
But no luck so far. using only os commands to define the directory
path should exclude any OS path formats issues I suppose? If I print
the paths they look just fine. I also tried hardcoding str(id) with a
predefined string but this doesn't work either, same problems arise.
Calling the script outside Django works fine (as did using the script
from Django 1.1.1), Also I find it strange that makedirs command rises
an error when calling from Django ("mkdir() takes exactly 1 argument
(2 given)"), but again outside Django this works just fine..
Hope anybody has any suggestions..
