Customizable Separator for slugify

2011-01-03 Thread Joe Jasinski 
Hi All,
  I'm wondering if anyone would find it useful to allow the slugify
function to take an optional argument that would let us specify what
type of separator to use.  Sometimes it might be nice to let slugify
use an underscore instead of a dash.  I see that slugify is grouped
with the template filters code so perhaps it's intent is only to be
used as a template tag, but I've seen people using it in raw python
code.

SUGGESTED PSUDOCODE

200 def slugify(value, slug_separator='-'):

208 return mark_safe(re.sub('[-\s]+', slug_separator, value))



ORIGINAL CODE
http://code.djangoproject.com/browser/django/trunk/django/template/defaultfilters.py

200 def slugify(value):
201 """
202 Normalizes string, converts to lowercase, removes non-alpha
characters,
203 and converts spaces to hyphens.
204 """
205 import unicodedata
206 value = unicodedata.normalize('NFKD', value).encode('ascii',
'ignore')
207 value = unicode(re.sub('[^\w\s-]', '', value).strip().lower())
208 return mark_safe(re.sub('[-\s]+', '-', value))
209 slugify.is_safe = True
210 slugify = stringfilter(slugify)

This is my first post on Django Developers, so I figure I'd introduce
myself.  My name is Joe and I'm a Django web developer in Chicago.
I've been working with Django for a few years and find it a lot of
fun!

If this is the wrong place to ask, my apologies.  Thanks for reading,

Joe

You might also try the django-nonrel forum [1]. Your question has
almost nothing to do with Django itself -- the problem lies somewhere
between AppEngine and the unofficial nonrel branch.

Sounds like a good idea to me.

I would head over the the django-users list (this one's for

Also, you might try Stack Overflow. It's a great place to get quick

Doc idea: Split request & response?

2011-01-03 Thread Adam V. 
The request & response docs for 1.3 look like:
Reference: Request/response objects | TemplateResponse objects


The first link has requests, associated request objects, and
responses. The second link has new derived response objects.

What does anyone think about reorganizing this to:
Reference: Request objects | Response objects


The Request and supporting objects stay on the first page, the
Response objects move to the 2nd page and the new TemplateReponse docs
get merged in.

I installed AppEngine SDK into /usr/local/google_appengine and I
modified my PYTHONPATH:

However, when I try to run the dev server, it shows this backtrace:

It looks like the "import yaml" command imports different yaml library
than SDK expects. I originally tried to setup the server with Python
2.6, but I also tried 2.5 with the same result.

I didn't google any solution successfully neither.

Thanks for any suggestion.

Re: Problem with ``Model.objects.create``

2011-01-03 Thread Yo-Yo Ma 
Oh, sorry for the confusion, and thanks for the explaination. I
thought that Django raised an IntegrityError in this case, and when it
didn't happen I figured it was a bug.

I will make a recommendation (observation). To provide a blank value a
a model and have it validate with full_clean, you have to specify
blank=True. I would suggest that to maintain integrity between your
applications logic and the database, Django should raise an
IntegrityError, if blank=False.
