Using Django, how do I generate the value of a field the first time it's accessed? Then storing the value on the field. In my case it's an image, but it could be anything I suppose. What I need is a function that runs before the field is accessed or wrapping the access and upon checking for nullness I generate it, or something like that...
Summary As I'm looking on stackoverflow and around the net, I find that there is a general lack of good documentation on best practices for caching a high performance site that uses sessions.

I have a django application using mod_python, fairly typical configuration except that media files are being served by a (I know, not recommended) 'media' directory in the document root. I would like to test and maybe deploy with mod_wsgi but I cannot figure out how to create something simple to serve static files. mod_python allows th...
I'm working on a Django app for hosting media (specifically audio and images). I have image galleries and photos separate in my model, and have them linked with a ForeignKey (not sure if that's correct, but still learning). What I need is for the Album class's __unicode__ to return the album owner's username. class Album(models.Model): ...
I'm a C#/.NET developer looking to mess around with something completely different - something LAM(*) stackish for building web apps quickly. I'm thinking either Django or Rails. I kind of like the Python language better and it seems to be more full-featured than Ruby for statistical, scientific and networking (let me know if you think ...
I'm doing some local development using Django and Satchmo. When I upload product images locally via the admin, the path to the image shows up as an absolute path, complete with drive letter, rather than the proper relative path. Stranger still, Satchmo saves both the original image and the thumbnails it generates in both me /media/ dir...

I know a site can have many apps but all the examples I see have the site called "mysite". I figured the site would be the name of your site, like StackOverflow for example. Would you do that and then have apps like "authentication", "questions", and "search"? Or would you really just have a site called mysite with one app called Stack...
When I have a valid Django form, I can access the data with form.cleaned_data. But how do I get at the data a user entered when the form is not valid i.e., form.is_valid is false. I'm trying to access forms within a form set, so form.data seems to just give me a mess. ...

In sqlite3 I can use strftime(), but that doesn't work with MySQL. In MyS...
