Create custom renditions from django url fields
Project description
django-url-renditions
django-url-renditions allows to define rendition process to django url fields. This works pretty well with https://github.com/bradleyg/django-s3direct and Heroku.
It comes with a Graphene Query
that enable renditions in your GraphQL schema.
Install
pip install django-url-renditions
Add url_renditions
to your INSTALLED_APPS
Define your model
from django.db import models
from url_renditions.fields import FileUrlWithRenditions
# django-url-renditions comes with a simple image resizer method.
# Look at the implementation if you need something more specific
from url_renditions.resize_image import ResizeImage
class Track(models.Model):
original_artwork = models.URLField()
artwork = FileUrlWithRenditions(
source='original_artwork',
use_job_runner=True, # if we want to queue the job with django_rq
renditions={
'small': ResizeImage('80x80'),
'medium': ResizeImage('300x300'),
}
)
That way, when a Track
model get created with an original_artwork
, artwork
will be automatically polulated with two renditions: small
and medium
.
To access them, use:
r = my_track.artwork.rendition_set.get(name='small')
print('url:', r.href, 'width:', r.width, 'height:', r.height)
Graphql with Graphene
Add url_renditions.graphql_schema.Query
to your root query.
import graphene
import url_renditions.graphql_schema # noqa
class Query(
...
url_renditions.graphql_schema.Query,
graphene.ObjectType):
pass
schema = graphene.Schema(query=Query)
Then when you ask for
{
track(id: "VHJhY2s6OA==") {
artwork {
renditions {
medium {
href
width
height
}
}
}
}
}
You get
{
"data": {
"track": {
"artwork": {
"renditions": {
"medium": {
"href": "https://images.unsplash.com/photo-1474314170901-f351b68f544f",
"width": 300,
"height": 300
}
}
}
}
}
}
