Hi group,
What would be a good way to log changes made to models from outside
the admin interface?
Thanks for any hint

Hi,
I write a POS application and several users share the same terminal.
They use a barcode scanner to point to their badge to login (works
already). I'd like to keep the session data for every user so that
when user A leaves the terminal and user B makes an invoice and user A
comes back to the t
User model.
Anyway I felt already that the User would quickly become an integral
part of the business model and as such needs to be extended.
Thanks for your help

Hi,
I'd like to implement a simple "create" & "update" form for my
"Partner" model using ModelForm. How can I make the difference in a
view "save" function whether the POST comes from a "creation" or an
"update" form? Unfortunately the primary-key seems never to be
included by default in the form
Sorry my old brain doesn't get it. Is there somewhere a complete CRUD
example using ModelForm?
Thanks

Hi again,
That's exactly what I did and the point is that it doesn't work! See

Sorry to insist, but that's what I don't understand here. How can I
know that the partner that is 'posted' is new or not? I really become
crazy here. I can't believe after all the good things I've discovered
in Django that this can be so hard.
Thanks for your time

as I said: maybe I'm on the wrong track with ModelForm ...

Of course! The mistake is that I didn't have the ID in the URL, but I
took the partner to be edited somewhere from the session. I'll change
the code and it should work as expected.
Thanks again for your patience

Hi,
I use a session to store several instances of different models coming

Hi,
Some time ago I asked if there is a way to aggregate on an expression
and I was told that it's not possible at the moment. I managed to use
a mix of aggregation and some arithmetics to reduce processing time by
a factor of 20 in critical areas of my application. While doing so, I
felt that so
lField()
quantity = models.DecimalField()
total = models.ExpressionField('price * quantity')
The SQL looks something like this for InvoiceLine.objects.all():
SELECT price, quantity, price * quantity AS total FROM invoiceline;

Hi,
I'd like to dynamically construct a form. Is there a way to do
something like this ...
from django import forms
my_form = forms.Form()
... and then add fields to my_form possibly along with their value.
I've tried to add the fields directly to the fields dictionary and
values to the data
I ran into the same problem and I found in the Python documentation
that the csv module has some Unicode issues ...
http://docs.python.org/library/csv.html?highlight=csv#module-csv
... with an attempt to getting around it with a wrapper ...
http://docs.python.org/library/csv.html?highlight=csv#
Answering to myself,
I got it to work with assigning to the 'fields' and 'initial'
attributes of the instantiated form. Again, I feel that this is a kind
of hack and may not work with future versions of Django.

Hi,
I don't understand why the following code produces an error (see
below):
>>> from django import forms
>>> from ishop.bo.models import Document
>>> d = Document.objects.get(pk=8)
>>> print d.date_due
2009-08-28
>>> class df(forms.ModelForm):
>>> class Meta:
>>> model = Documen
Here is the definition of the field:
date_due = models.DateField(auto_now_add=True)

That function should at least return somewhere, I guess to the caller
which might be a "view" function that returns a HttpResponse.
Anyway, You should consider putting code that updates the database in
the "model".

Hi Group,
I wonder if there's a way to aggregate an expression like:
Sum("quantity*price")
on a model having "quantity" and "price" fields.

Thanks Alex, but then I wonder if it would be reasonable to move this
kind of simple rules to a "view" in the database and let Django access
the view rather than the raw table.
Any experience with that?

I wonder if I can use the Q object to build queries interactively and

queries for later

Let's say that I have a proxy model of the User model that adds some
