I'm creating a web app with Django. Since I'm very familiar with Apache I setup my development environment to have Django run through Apache using mod_wsgi. The only annoyance I have with this is that I have to restart Apache everytime I change my code. Is there a way around this? ...
Hello, I wrote a simple contact form for a client in Django. However, whenever it sends e-mail, it wraps the header values in u'' objects. For example, the From: header is From: (u'[email protected]',) Here's the code that sends the message: The form: class ContactForm(forms.Form): name = forms.CharField(max_length=100) sender = for...

I've tried several methods for removing form.data, but I keep getting a This QueryDict instance is immutable exception message. Is there a proper way to clear individual form fields...
There's lots of good conference videos online regarding Python and Django development. Instead of watching ST:TNG at the computer, I figure it'd more productive to hone my knowledge . Fire away with some of your most inspiring and educational Python, Django, or simply programming related talks. Provide an explanation of why you found th...

I use django-1.1 and satchmo (commit: 1385 75a2ea838067) I found that if there is a "love" speech in the slug item, for example, love-x10, dsfdsfloveddd, love-love ... the product's url is "http://example.com/product/lovelove/", if you click "add to cart" button, the server give me a Blank Page, Empty!

I am using django's inline formset factory. To use the example in the docs, author = Author.objects.get(pk=1) BookFormSet = inlineformset_factory(Author, Book) formset = LicenceFormSet(request.POST, instance=author) will create an inline formset to edit books by a particular author. I want to create a formset that only allows users ...

How to filter objects with an "author" from a set of "authors"(Users)? The "objects" are Posts, having an author(ForeignKey to User). I'm pretty much stumped by this, so I'd appreciate help with it. Of course one could go about this the naive way, by manually filtering them, but that would hit the database real hard. Thanks anyway. E...
Is it possible to have Django automatically delete formsets that are not present in the request? So for example if I had three inline formsets represented in HTML when I loaded my edit page and I use javascript to remove two of those when the request is processes Django sees that those two forms are no longer their and deletes them. ...

In this excellent Google Tech Talk by Jacob Kaplan-Moss, Jacob says that they added support for the include template tag despite previous dogmatic objections, and says that people shouldn't use it. Does anyone know why? A quick search didn't show anything that would explain why. There's nothing relevant in the now-fixed ticket where sup...
I'm attempted to extend code, and have come across an issue, I don't understand a line of code. I know the outcome of it - but I don't understand how it happens and am naturally enough scared to change it. The line of code I've come across is this: MyGenericRelation().contribute_to_class(model, 'field_name') The result of this code i...
