This could be configured manually, but it would violate DRY! I would basically have +-8 urls that basically do the same thing. So here is wha...

In PHP this would be trivial for me... I'm using a color picker (farbtastic) w/ Django Admin, it's the only on...

This is probably obvious and documented somewhere but I can't seem to find it: what's the syntax for using FieldField.name in a django filter query?

One of my models has attributes that are not stored in the database. Everything is fine at the view and model level but I cannot seem to display these 'non-database' attributes in my template.

Hi - I'm building a site for a client that needs to support image uploads (an artist) through the admin interface. Since most of the images are pretty high-res, I wanted to create thumb copies of the image to display on the gallery page after the upload.

Is there a way to force Django models to pass a field to a MySQL function every time the model data is read or loaded?
