Hi.
I have a collection of apps where I find repeating myself when rendering
tables in the templates.
In the stylised example below I have three types of tables, foo, bar and
baz.
Each app is supposed to render various combinations of tables from its own
models, but also from other models' tabl
class, but not from the parent class.

Hello.
I have a parent Meta class and some child classes.
I would like to read the decimal_places attribute from DecimalField of my
child instances using a function in my parent class.

Dear Django users.
I'm trying to do the sums of the product of two columns ('contract_sum' and
'probability', decimal fields), grouping by a third column, 'stage' (a
choice variable).
I'm also reporting the grouped sums of one of the single columns
('contract_sum')
The single column works just

error:
'str' object has no attribute '_default_manager'
So it certainly seems that using model=i will not pass the model name.
Is this because the argument for model= expects not a string but an object?
thanks, Mikkel

I have a lot of models (say 30 or 40) which are so similar, that I have
handled them using slightly modified class based views.
In urls.py:

Hi.
Once again thanks for all your invaluable advice to me so far. Now, I'm
battling context_processors.
I really struggle to find a good example that can help me understand how to
use them.
They seem quite helpful to a lot of stuff I plan to do.
I think I got the configuration in settings.py a

Dear Django users.
Thanks to the good advice of many people on this list, I've managed to
create some nice generic class based views that work simultaneously with
many models.
The models may differ from each other with regards to the number of columns
in their data tables as well as the naming
t is invalid, making your code try to do something weird.

Dear Django-users.
I'm slowly working towards a Django "data-warehouse" framework, where I can
easily add a lot of models (each containing a table with data), while
sticking to only few reusable views.
I've realised that in urls.py, it is possible to specify the model on which

Dear Django users.
I'm testing whether Django is a good choice for a web based application
that I need to handle (create, read, update, delete) a lot of data tables.
I've discovered the built-in Class Based View, which are going to save me
from a lot of repetitive code lines - yay!
Now, I've g
eeded.

Hi.
I'm new to Django, and I'm working my way into Django by going through the
nice Djangoproject.com turorial.
I'm trying to find out whether Django is the right tool for my task, which
is maybe a bit unusual for Django.
My task is to build a web interface to a database for an calculation too
