Hi,
I have this app which has an ImageField, where the image needs to be
cropped, resized, and a few effects (all from PIL) are applied on it, the
model looks something like this
class MidPanel(models.Model):
....
.....
image = models.ImageField(upload_to="images"):
def save(self):
........
if self.image:
dosomething(self.image)
Everything is fine, expect that every time someone makes a change to a field
in the model, the images gets manipulated. The image manipulation is
supposed to happen only once.
What I want is somehow to apply the cmanipulation on self.image only if the
image is changed, or its been created... Is pre_seave the right way, if so
how do you actually use it where it need to compare previosly stored data
and the newone and then only execute.
