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="imgs")
def save(self):
if self.image:
dosomething(image)
doanother2(self.image)
All this is fine. Expect that every time the model is saved, it executes the
manipulation on the image. What I require is an idea where the image
manipulation happens only if the image field is changed, and not unless. How
do I achieve that.
Someone suggested me to use pre_vae signal, but I am not able to figure an
effcient way..
Can someone help....
