Noticed some strange behaviour of request.GET.get()
Hi.
There's a simple code in urls.py:
==
def ls (request):
import os
out_html = ''
home_path = '/home/www/test-django'
# subdir_path = request.GET.get ('subdir')
subdir_path = 'public_html'
for root, dirs, files in os.walk (os.path.join (home_path, subdir_path)):
out_html += "%s\n" % root
return HttpResponse (out_html)
==
There's a catalogue in "home_path/subdir_path" which name
includes cyrillic symbols (фыва):
$ pwd
/home/www/test-django/public_html
$ ls -la
drwx---r-x 4 test-django test-django 111 Apr 6 20:26 .
drwx--x--- 13 test-django test-django 4096 Apr 6 20:26 ..
-rw-r--r-- 1 test-django test-django 201 Apr 6 17:43 .htaccess
-rwxr-xr-x 1 test-django test-django 911 Apr 6 16:38 index.fcgi
lrwxrwxrwx 1 test-django test-django 66 Mar 28 17:34 media -> ../
python/lib64/python2.5/site-packages/django/contrib/admin/media
drwxr-xr-x 2 test-django test-django6 Apr 6 15:48 фыва
My code works correct, here's the result:
$ curl -s http://test-django.example.com/ls/
/home/www/test-django/public_html
/home/www/test-django/public_html/фыва
But if I change "subdir_path = 'public_html'" to
"subdir_path = request.GET.get ('subdir')" then the request:
$ curl -s http://test-django.example.com/ls/\?subdir=public_html
leads to an error:

I don't understand it why "subdir_path" getting the same very value in one case
works perfectly and in the

Re: Noticed some strange behaviour of request.GET.get()
Hi Bill Freeman.
1. I don't know. Actually I'm not really a django-programmer, I'm only
busy with debugging. But IMHO, in this case it doesn't really matter
where the code is, it should work in urls.py too.
2. subdir_path u'http'

Re: Noticed some strange behaviour of request.GET.get()
Thanks, subdir_path = str(request.GET.get('subdir')) is what I needed.
I'm grateful to everybody for detailed answers. Thank you.
