drf-imgproxy 1.1.0

Serialize Django's ImageField into imgproxy URLs for your Django REST Framework APIs to generate thumbnails.

Serialize Django’s ImageField into imgproxy URLs for your Django REST Framework APIs to generate thumbnails.

Important Notice

This package only provides the serializer class necessary to translate your ImageField to signed imgproxy URLs.

It does not provide anything to upload images to your object storage bucket. We suggest you use another Django storage backend library that’s able to communicate with your object storage solution, in particular we recommend the following:

• django-storages

• django-minio-storage

Usage

0. Installation

You can easily install this package from PyPI with pip by doing:

pip install drf-imgproxy

1. Quickstart

In settings.py:

INSTALLED_APPS = [
  ...
  'drf_imgproxy',
  ...
]

# Configure this to either of the following:
#  - 's3' for Amazon S3, Minio and any other S3-compatible object
#    storage
#  - 'gs' for Google Cloud Storage
#  - 'abs' for Azure Blob Storage
IMGPROXY_PROTOCOL = 's3'

# Set the following to the bucket name that imgproxy uses.
IMGPROXY_BUCKET_NAME = 'nerv_angel_captures'

# Set both of the following to the appropiate values of
# `IMGPROXY_KEY` and `IMGPROXY_SALT` of your imgproxy server.
IMGPROXY_KEY = 'ThisIsNotASecureKeyAtAll'
IMGPROXY_SALT = 'SeriouslyThisSaltIsVeryInsecure'

# Set the following to the publicly accessible URL of your imgproxy
# server.
IMGPROXY_HOST = 'https://imgproxy.infra.nerv.tld'

# Set the following variable to the available resolutions your API
# provides.
#
# The format is `(<width>, <height>)`.
IMGPROXY_RESOLUTIONS = (
    (640,  480),
    (800,  600),
    (1024, 768),
)

# In case you want to skip imgproxy url generation, set this flag to True.
# When generation is being skipped, all the resolutions return the url of
# the source file if possible or None.
IMGPROXY_SKIP = False

In serializers.py:

...
from drf_imgproxy.serializers import ImgproxyResizeableImageField
...


class AngelActivity(ModelSerializer):
    ...
    captured_photo_thumbs = ImgproxyResizeableImageField(
        read_only=True,
        source='captured_photo'
    )
    ...
