Project Description

Design:

  • Uses Django Storage API
  • Uses flexible meta data store. Database and Redis metadata backend supported at the moment.

Installation

  • Add thumbnails to INSTALLED_APPS in settings.py.
  • Run python manage.py migrate to create database metadata backend.

Usage

settings.py:

THUMBNAILS = {
    'METADATA': {
        'BACKEND': 'thumbnails.backends.metadata.DatabaseBackend',
    },
    'STORAGE': {
        'BACKEND': 'django.core.files.storage.FileSystemStorage',
        # You can also use Amazon S3 or any other Django storage backends
    }
    'SIZES': {
        'small': {
            'PROCESSORS': [
                {'PATH': 'thumbnails.processors.resize', 'width': 10, 'height': 10},
                {'PATH': 'thumbnails.processors.crop', 'width': 80, 'height': 80}
            ],
            'POST_PROCESSORS': [
                {
                    'processor': 'thumbnails.post_processors.optimize',
                    'png_command': 'optipng -force -o7 "%(filename)s"',
                    'jpg_command': 'jpegoptim -f --strip-all "%(filename)s"',
                },
            ],
        },
        'large': {
            'PROCESSORS': [
                {'PATH': 'thumbnails.processors.resize', 'width': 20, 'height': 20},
                {'PATH': 'thumbnails.processors.flip', 'direction': 'horizontal'}
            ],
        }
    }
}

If you prefer to use Redis as your metadata storage backend (like I do :):

THUMBNAILS = {
    'METADATA': {
        'PREFIX': 'thumbs',
        'BACKEND': 'thumbnails.backends.metadata.RedisBackend',
        'db': 2,
        'port': 6379,
        'host': 'localhost',
    },
}

In python:

import thumbnails

class Food(models.Model):
    image = thumbnails.Field()


food = Food.objects.latest('id')
food.image.thumbnails.all()
food.image.thumbnails.small  # Generates "small" sized thumbnail
food.image.thumbnails.large  # Generates "large" sized thumbnail
food.image.thumbnails.small.url  # Returns "small" sized thumbnail URL

django-thumbnails comes with a few builtin image processors:

# To use the following processors, put the arguments of processors in SIZES definition
thumbnails.processors.resize(width, height)
thumbnails.processors.rotate(degrees)
thumbnails.processors.flip(direction)
thumbnails.processors.crop(width, height, center)

Processors are applied sequentially in the same order of definition.

Management Commands

If you changed your size definition and want to regenerate the thumbnails, use:

python manage.py delete_thumbnails --model=app.Model --size=thumbnail_size_to_delete

Running Tests

To run tests:

`which django-admin.py` test thumbnails --settings=thumbnails.tests.settings --pythonpath=.
