It should:
>>> import re
>>> re.match(r'^portal/student/(?P\S+)/profile_edit/$',
'portal/student/xx.yy/profile_edit/').groupdict()
{'userid': 'xx.yy'}
>>>
I don't know what to tell you. The regex now matches the url you specified.
url mapping isn't fundamentally broken in Django. There's got to be
something else going on in your scenario...

Admin builds that list of possible pages you can jump to using its own custom tag, the heart of the code is here: http://code.djangoproject.com/browser/django/tags/releases/1.1/django/contrib/admin/templatetags/admin_list.py#L28 The tags used by the admin are generally not documented for use by other apps.

Re: PostgreSQL or MySQL, What are the +'s and -'s?
Thanks, that is a good example. Back to the original point of the post. It looks like I'm going to be doing a lot more work with PgSQL. I see they are working to put replication in the core in the next major subversion (which honestly I rarely need). The real kicker for me is that PgSQL seems to have all of the query features I've been missing in MySQL. I'm generally creating CRUD applications and then data reporting. It seems like the combo of Django and PgSQL is really where it's at for me. I just completed the bulk of my first Django app and I'm eating it up. So much so that I almost immediately jumped into the core to see how I could help. It's like this entire new world of speed and efficiency was just dropped in my lap and I only want to help make it better. I have both Practical Django and Pro Django on their way. :o) Thanks for this thread. This group has always been a great help!

Django is not removing the values. Rather the browser does not send to the
server values for form elements that are disabled when the form is
submitted. The HTML 4 spec here:
http://www.w3.org/TR/REC-html40/interact/forms.html#disabled notes in
discussing an example "Therefore, it cannot receive user input nor will its
value be submitted with the form."
By setting the element to disabled you have done essentially the same thing
as excluding it from the from (as far as Django can see), and you are
similarly responsible for supplying values for fields that are not contained
in the submitted form. See the note here:
http://docs.djangoproject.com/en/dev/topics/forms/modelforms/#using-a-subset-of-fields-on-the-form

regex problem in urls.py in Django 1.1/mod_wsgi
Hi, I'm using this regex in urls.py: r'^portal/student/(?P\S+)/profile_edit$' to try to match this url: http://dd..org/portal/student/xx.yy/profile_edit/ It's supposed to put "xx.yy" into userid parameter and match and use the associated view. But it doesn't match. I've banged my head for hours with regexes and don't see why not. Why won't this work?

Re: PostgreSQL or MySQL, What are the +'s and -'s?
++ Zberteoc for the link to the comparison. w.r.t. using triggers/procedures. If a database is getting updated by multiple applications then using triggers/procedures to move duplicated business rules into the database starts to make some sense-- even more so if you don't have good control over all the applications that are doing the updating.

Re: Parsing / Deserializing a JSON String
Thank you for your input. I tried what you suggested by first just
trying to loop through the data like so:
"
test_output = 0
for obj in serializers.deserialize('json', gantt_data)['ganttgroups']:
test_output = test_output + 1
"
This generated the following error:
"'generator' object is unsubscriptable"
I tried changing it slightly, moving "['ganttgroups']" inside the
brackets, to this:
"
test_test_output = 0
for obj in serializers.deserialize('json', gantt_data['ganttgroups']):
test_output = test_output + 1
"
This generated the error I originally received:
"string indices must be integers"
I am just so new to this that I'm not sure where to go from here. Do
you have any other suggestions as to what I may be doing wrong?
Again, any help with this would be greatly appreciated.

WRONG: local_dt = datetime (dt.year,dt.month,dt.day,dt.hour,dt.minute,dt.second,tzinfo=local_timezone) RIGHT:local_dt = local_timezone.localize(datetime (dt.year,dt.month,dt.day,dt.hour,dt.minute,dt.second)) On Sep 5, 2:47 pm, zweb wrote: > Converting from local to utc: > > local Timzone: America/Los_Angeles > local_dt 2009-09-17 00:00:00-08:00 > utc_dt 2009-09-17 08:00:00+00:00 ( after converting from local to utc) > > when I convert back from UTC to America/Los_Angeles, I get back > local_dt 2009-09-24 01:00:00 > > which is one hour from where I started.

django pagination
Hi, Apologies if this question has been asked before but I was not able to find a satisfactory answer. In the django admin app there is a capability to have a pagination object that lists the number of pages that can be paged. I have found code that uses the django Paginator object which builds a navbar that looks like this previous The documentation for the Paginator tag (seems to be non-native) on the django site shows what I want. But is an example that uses a custom template. This is also clearly a custom tag. How do I use the django admin navbar in my app? I want it to display something like [1] [2] [3] [...] [30] and do it natively.

TIME_ZONE = 'UTC' how does it work?
I am on mac os x and linux. I use mysql How does the TIME_ZONE='UTC" in django settings.py work? If i enter date time from web page and store it in mysql db. And no timezone is associated with the datetime, does django assumes datetime is in UTC and saves it without changing or does it assume it is in local timezone of the server django is running on and converts it in to utc? Can anyone explain how does django use TIME_ZONE in settings.py.

Django remove value from field with attrs disabled="disabled"
Hi,
I have problem with Django Forms and field with set attrs to
disabled="disabled"
# forms.py
class EditForm(forms.ModelForm):
def __init__(self, *args, **kwargs):
super(EditForm, self).__init__(*args, **kwargs)
self.fields['title'].widget.attrs.update({'readonly':
'readonly', 'disabled': 'disabled'})
class Meta:
model = MyModel
fields = ('title', 'tagline')
# views.py
form = EditForm(request.POST, instance=my_instance)
if form.is_valid():
form.save()
# models.py
class MyModel(models.Model):
title = models.CharField(max_length=120, db_index=True)
tagline = models.TextField(, max_length=500, db_index=True)
And now, Django remove values form field with attrs 'disabled':
'disabled' ("readonly" without "disabled" works fine, but I need
disabled option in my html output). Why Django do that?
Thanks for help.

Re: PostgreSQL or MySQL, What are the +'s and -'s?
Great site! thanks With my SQL experience, your comment about database coding seems to ring true. The database is a much different environment, with different paradigms, than a standard application environment. When you really need database coding you know it (kind of like meta programming). So far from my experience has been, the times I found we needed database programming were pretty simply speed related, so difficult to distinguish from application logic. What types of situations do others find useful for stored procedures and triggers?

Re: PostgreSQL or MySQL, What are the +'s and -'s?
This is a common mistake almost all non SQL developers make thinking in procedural/programming language terms in regards wit SQL and database coding. If you're asking me there is nothing cool in the feature of creating stored procedures in other than the SQL language. MS-SQL introduced that with 2005 version, CLR integration, but I is hardly used for one very simple reason it is NOT really necessary. SQL code needs to be understood first and only then look elsewhere. Anyways, in terms of comparison PgSQL vs MySQL here is a very detailed wiki: http://www.wikivs.com/wiki/MySQL_vs_PostgreSQL I have never used PgSQL but i wouldn't hesitate to use it if I needed it. All DBMS these days are robust and mature enough to be able to rely on them. It comes in the end to what you prefer, how comfortable you feel and ease of use, rather than how many terrabytes they can deal with as the features lists are more and more the same for all of them. Support and online community is also very important, probably the most if you're novice in both, and here MySQL prevails as it is far more popular. Cheers.

Using apache.interpreter imported from mod_python > seems to work just fine. It should be pointed at that the leakage of environment variables between sub interpreters is not actually mod_python's fault. It is a combination of an issue with Python itself triggered by what the mod_python handler for Django does. In other words, not the fault of mod_python itself. The underlying issue is that when os.environ is set, this triggers a call of putenv() in C library to promote the variable to a process wide variable. A Python sub interpreter created after that point, will have that environment variable copied into its os.environ. Normally, for SetEnv directive this wouldn't make the least bit of difference because SetEnv directive normally doesn't promote the set values to process wide environment variables in the Apache server child processes themselves. Normally they would only be set up in sub processes created specifically for CGI scripts. The table of such SetEnv variables is though still available to mod_python, but in a distinct data structure. Django unwisely copies those variables in its mod_python handler and promotes them to process wide environment variables. This was done so that SetEnv could be used to set DJANGO_SETTINGS_MODULE. Django should really only have promoted that single variable and better still should never have relied on process environment variables to begin with. Unfortunately, not something that can easily be changed now. Anyway, you will not have an issue if instead of using differently named environment variables for each site, you use the same environment variable name and just set them different. That is, use the value of the single environment variable to distinguish rather than the name of the variable. Better still, stop using mod_python. Instead, use mod_wsgi and its daemon mode to separate the two instances in completely different processes and therefore never risk environment variable leakage or any of the other issues arising from running multiple Python web applications in different sub interpreters of the same process.
