Save a thumbnail in Django model
You can save space on server & speed up your speed by saving a thumbnail of an image. Sometimes we don't want to save images with size of 3 MB or 5 MB or even more, so can save just a thumbnail of that image for better performance of our app:
from PIL import Image # pip install pillow
class Profile(models.Model):
# other fields
image = models.ImageField(upload_to="path/to/be/saved")
def save(self, *args, **kwargs):
super(Profile, self).save(*args, **kwargs)
img = Image.open(self.image)
if img.height > 200 or img.width > 200:
new_size = (200, 200)
# image proportion is manteined / we dont need to do extra work
img.thumbnail(new_size)
img.save(self.image.path)
