I am using pdfLaTeX to generate the PDFs on the fly and serve them via
Django after dumping ReportLab.

That did it! Thanks. I also needed zlib, I think?

template. Everything executes according to plan, but I get no data
outputted into the fields using obj

Never mind. Sorry for the trouble.

Hi Djangonians,
I recently had an instance where it would have been really convenient
to see the error and a traceback in the ``runserver`` console instead
of just a single line telling me that the request returned a 500
error.
In the event of blind debugging, where a 3rd party tool is performin
I'd like to create a front facing poll creation form that can
automatically handle deletion, reordering of choices.
I believe formsets are the easiest way to accomplish this. I start
with 3 choices and want to allow the user to add more.
Check the following code:
def create(request):

Hi all!
I'm working on an app which has two classes:
# This one records acedemic journal name and related infomation:
class Journals(models.Model):
Name = models.CharField(u'Journal', max_length=200, unique=True)
IsSelected = models.BooleanField(u'If it is a special journal',
def
I do the reports in HTML, using django templates and then instead of
send the rendered result to the browser, I filter it throught htmldoc
linux utility.
Works like a charm for me.

How much of django's code is broken with python 3.0?
I'm not that deep into Python, (yet). So, it strikes me that maybe
I'm better off installing 3.0 and learning that rather than sticking
to 2.5.
But, I don't want to find out I have to go and relearn django all over
again.

The installation instructions and the installation FAQ cover this issue:

I'm writing a library app - would like to find out if it is possible
to have a dynamically updating (returndate) field in a model?
class Loan...
...
borrowdate = models.DateTimeField(auto_now_add = True)
returndate = models.DateTimeField(timediff(borrowdate+ timedelta
(days=2))
...
--~--~--
Is there a way to calculate and store the average rating in this
example:
RATING_CHOICES = {
'3' : 'Excellent',
'2' : 'Good',
'1' : 'Poor',
}
class Loan(
...
book = models.ForeignKey(Book)
rating = models.IntegerField(choices=RATING_CHOICES)
...
class BookRatings(...
...
book = mod
Lol.
Just looking at the time between posts - did it really take 45 min to
figure that out?
I find it amazing as I often lose days like that!

I highly recommend:
http://code.google.com/p/django-pagination/
Very easy to implement, requires no modifications to views or models,
purely template based (via template tags).

So I need to display the data for a form field from the post or from
the instance if no post. This works but I am hoping there is a better
way:
{% if form.is_bound %}
{{ form.data.foo }}
{% else %}
{{ form.instance.foo }}
{% endif %}
Any suggestions?

Do I have to use Manager when do cross-table querying such

tb1.name,
tb2.name as tb2_name
FROM
tb1 I
tb1.objects.extra(select={"tb2_name": "app_tb2.name"},where=["app_tb1.name=

Hmm... this is slightly different... is BookRatings and Books 1 to 1?
If I store these aggregates as part of the class that it's grouping
by. Here's how I do it for restaurants:
class RestaurantRating(models.Model):
restaurant = models.ForeignKey(Restaurant)
value = models.IntegerF
I currently serve up images via the DB vs. filesystem. I did this in
order to keep the data in one place, but I now regret it.
I'd recommend overriding the delete() of your image class to take care
of deleting the related image from your storage.
Depending on your needs and the amount of data,
I have a model that refers to a ForeignKey, e.g.:
class Template(models.Model):
type = models.ForeignKey(Type)
...
class Type(models.Model)
name = models.CharField(max_length=32)
...
I can fetch these objects fine using the model API.
t = Template.objects.get(id=1)
print t.type
>>
print t
Thank you very much Malcolm. The methods I listed above has worked for
me so far - so your response is reassuring.
I was just surprised that no one had encountered a similar need
already. The concept here is parallel to getting a list of
territories in a country, dynamically fetched based on the
32 matches
