I'm a bit confused on a few points here. The upload_to field attribute should be atomic to the imagefield - it doesn't rely on related models.
your change_upload_to creates a new screenshot - but doesn't connect it to the current WebProject instance. Is that what you are trying to do? s = ScreenShot(project=instance) Is there a reason your WebProject is not defined when you create a screenshot in your view? Something about this seems like it is making it more complicated than it needs to be. but details are lacking t -Preston On Nov 24, 5:52 pm, neridaj <neri...@gmail.com> wrote: > Hello, > > I'm trying to change the upload_to attribute of an ImageField so that > it is in the format "web_projects/year/slug/".
