upload_to not found
Hi,
I was trying out a form - with filefield. I used the option upload_to, and
django server erred out saying - upload_to not found.
I checked django code :
>>> import django
>>> django.VERSION
(1, 0, 2, 'final', 0)
class FileField(Field):
widget = FileInput
default_error_messages = {
'invalid': _(u"No file was submitted. Check the encoding type on the
form."),
'missing': _(u"No file was submitted."),
'empty': _(u"The submitted file is empty."),
}
def __init__(self, *args, **kwargs):
super(FileField, self).__init__(*args, **kwargs)
--> As we can see there is no upload_to parameter in it. I am sure I am
missing something because upload_to seems to be the basic option as per
documents.
Can somebody help me out?
Regards
K

Django: creating formset is very slow
Hi all,
My web application sends a medium size data grid (20 elements). I was
using formsets for the same.
The issue I am facing is that the formset instantiation is very very
slow. I timed it and it is taking ~4-7 seconds for it to instantiate.
Is there someway the speed can be increased?
There are no files sent. I am planning to, later.
The code:
logging.info('Start - %s' %time.clock())
DataFormSet = formset_factory(DataForm, extra=25)
logging.info('Formset Class created- %s' %time.clock())
formset = DataFormSet(request.POST, request.FILES)
logging.info('Created new formset- %s'%time.clock())
>From my logs:
2009-01-06 22:53:30,671 INFO Start - 0
2009-01-06 22:53:30,671 INFO Formset Class created- 0.000403403225829

Django forms usage with mutliple rows
Hi, Since I am a newbie in HTML and Django, there might be a completely different way to do this. If somebody can point that also, it would be helpful. I want to send multiple rows of data from a datagrid to a django server. Currently, I am doing it in a single form inside a page with the parameters as array. Please note that this value can change from 1 row to 25 rows. The example get statement for 3 rows would look like: ../send_multiple_values_through_one_form.html?foo[secret]=my+hidden+value&foo[product-id]=1&bar[secret]=my+hidden+value&bar[product-id]=2&baz[secret]=my+hidden+value&baz[product-id]=3 Now, I want to use Django forms to validate this data. class UploadQueryForm(forms.Form): secret = forms.IntegerField() product_id = forms.CharField(max_length=50) But this can be used to handle only one row . How can I use this for multiple rows? Is Django Formsets used for this purpose? Please note that I am not averse to other ideas - (say multiple forms etc), but I cannot think of any other way to implement this from HTML perspective itself.

Re: Creating a custom sql query
oops!! Unknowingly send the mail before finishing it. As I was mentioning in the earlier mail: What I want is: dbmodel.objects.filter(__first_filter).sum(), should be able to sum across the filtered data. If somebody could help me out on this, I would be very thankful. P.S-> Also, is it safe to use the backends.quote_name for getting the name of the table in the DB? Is there any other mechanism to get the original name of the table?
