I'd like to find an efficient method to retrieve a list of Django DB
records (model has a DateTimeField `timestamp`) between datetime
'start' and datetime 'end' with a few conditions. First, we're looking
for a record once every 'interval' minutes. Second, I only want a
record if it's timestamp wi
Good idea Thomas. I'll experiment with using __range to get 24
individual records instead of retrieving all records and then looping
over the queryset. Thanks.

I'm having a problem with django admin working for one local project
and not another. Both use the same version of Django (SVN-12311). Both
have very similar settings.py files.
The issue appears when I click on an app model class name in the root
admin list (at "/admin/"). In this case I was tryin
Two additional notes for this issue:
1. Clicking on _any_ model in the admin causes the same TypeError.
2. Clicking on "+Add" in admin for the User model yields a blank form!
Clicking on "+Add" for any other model shows a valid form.

Just a clarification, the model instance save is being done via
form.save(), not directly from the instance.

ffect on where the uploaded files are stored, so I added
this "save_FOO_file" method to the ToolRun model class:
def save_input_file_file(filename, raw_contents):
# save it in the correct subdir
According to the debugger, this function is never called.

Using the conventional Blog and Entry models from the Django database
API docs:
class Blog(models.Model):
name = models.CharField(max_length=100)
...
class Entry(models.Model):
blog = models.ForeignKey(Blog)
headline = models.CharField(max_length=255)
The best I've been able to come up with is:
qs1 = Blog.objects.all()
qs2 = qs1.filter(entry__blog__isnull=False)
qs3 = filter(lambda x: x not in qs2, qs1)
Surely there is a better method.

Lots of people correctly suggest using named url patterns and the {%
url %} template tag to obtain a URL. The concept is great and follows
the DRY principle. However, I believe that if a pattern has an
"include()" instead of a view function, the existing
mechanism fails. An example of the problem,
er apparently ignores
the kwargs when presented with a function instead of a named URL.

I'm struggling with a newforms issue. Specifically I'm trying to pre-
select an option in a ModelChoiceField and I cannot figure out how
this can be accomplished. Here are the code snippets:
class Account(models.Model):
title = models.CharField(maxlength=30, unique=True,
db_index=True
Doh!
If I had taken the time to read a post from two hours earlier I would
have seen the answer. Use "initial" when instantiating the form. The
last line below does the trick.
if request.method == 'POST':
form = FormClass(request.POST)
if form.is_valid():
project =
Hi all,
Two newforms questions...
1. Is there an easy way to get the new object created by form.save()?
2. Is is true that one should not call form.save() if the form was
instantiated from a class resulting from form_for_instance()?
Thanks,
Graham

Thanks, I finally saw that after perusing the django source code.

Sure, works great. My favorite (and perhaps most useful) feature is
debugging a Django app and stepping through both my code and the
Django code to find out what is happening.

Hi,
I'm having a problem with Django "HTML escaping" JSON data sent in
response to an asynchronous form submission when the form has an
field. Forms that don't have a file field
yield proper responses, and when Javascript is disabled on the browser
normal form submissions work as well.
