How can I generate thumbnails in Django using advanced techniques?

You can use the Pillow library along with Django's ImageField to create thumbnails. Would you like a code example?

Yes, please provide a code example for generating thumbnails.

Sure! Here's a simple example:

from PIL import Image
from django.db import models

class MyModel(models.Model):
    image = models.ImageField(upload_to='images/')

    def save(self, *args, **kwargs):
        super().save(*args, **kwargs)
        self.create_thumbnail()

    def create_thumbnail(self):
        img = Image.open(self.image.path)
        img.thumbnail((200, 200))  # Set the size of the thumbnail
        img.save(self.image.path.replace('images', 'thumbnails'))

What if I want to generate multiple sizes of thumbnails?

You can modify the create_thumbnail method to accept size parameters and call it multiple times for different sizes. Would you like to see that?
