Features

This Sample illustrates the following concepts on top of the Django Framework:

• Using django-material and materializecss for building Django UI.
• Using django-imagekit for building resizing images.
• Using photoswipe javascript library for more rich image gallery user experience.

Control the image size and quality

The picture size and quality can be controlled programatically from the models.py. Just change the processors. For more information see django-imagekit.

class AlbumImage(models.Model):
    image = ProcessedImageField(upload_to='albums', processors=[ResizeToFit(1280)], format='JPEG', options={'quality': 70})
    thumb = ProcessedImageField(upload_to='albums', processors=[ResizeToFit(300)], format='JPEG', options={'quality': 80})
    ...

Sample data cleanup

To cleanup the sample data delete the sql lite database and the media folder files. Create new database and run the sample again.

No validation on the form

This is sample. I decided to keep it simple and let the validation to be added by you.
