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.

Re: Noticed some strange behaviour of request.GET.get()

2010-04-07 Thread Bill Freeman 
String concatenate, format, comparison, indexing a dictionary*, all
work with mixed
types, unless the conversion from unicode to byte string can't be done with the
current codec when forced to bytestring, in which case you get a
suitable exception.

Besides, this wouldn't explain why the value of subdir_path is coming up u'http'
when his url is ...?subdir=public_html .


(Officially, attribute names, though used to do lookups in __dict__,
are not permitted
to have non-ASCII characters, according to the PEP that Karen often quotes.)

I think I know the reason for the difference in hard-coding the string
vs getting it from request.GET.

Django always uses unicode strings internally, and this includes GET
parameters. So your 'public_html' string is actually being converted
to u'public_html', as you can see if you print the contents of
request.GET. But your hard-coded string is a bytestring. If you used
the unicode version - subdir_path = u'public_html'  - you would see
the same result as with the GET version.

As to why this is causing a problem when combined with os.walk and
os.path.join, this is because of the rather strange behaviour of the
functions in the os module. If you pass a unicode path parameter to
them, they return results in unicode. But if you pass a bytestring
parameter, the results are bytestrings. And since you have not
declared a particular encoding, Python assumes it is ascii - and of
course your Cyrillic filenames are not valid in ASCII.

The problem should go away if you are careful to define *all* your
strings as unicode - it is the mixture of unicode and bytestrings that
is causing the problem. This means:
out_html = u''
home_path = u'/home/www/test-django'
...
out_html += u"%s\n" % root

Re: Noticed some strange behaviour of request.GET.get()

2010-04-07 Thread Nuno Maltez 
The only difference I can see is that

request.GET.get ('subdir')

will return an unicode string, u"public_html", instead of a normal
string, 'public_html'.


If it works with the byte string, try changing the line to

subdir_path = str(request.GET.get('subdir'))

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()

2010-04-07 Thread Bill Freeman 
1.  Why is this view code in urls.py?

2.  What is the value of subdir_path in the trace back?  (There's a
little arrow you can click to
see the variable values fro the frame.)

Noticed some strange behaviour of request.GET.get()

2010-04-07 Thread Alexey Vlasov 
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:

Request Method: GET
Request URL: http:// test-django.example.com/ls/

 'django.contrib.auth.middleware.AuthenticationMiddleware')

Traceback:

File "/usr/lib64/python2.5/posixpath.py" in isdir
  195. st = os.stat(path)

Exception Type: UnicodeEncodeError at /ls/
Exception Value: 'ascii' codec can't encode characters in position
 45-48: ordinal not in range(128)

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