Offload sorl thumbnail rendering to a render view.

Installation

Usage

Note

Make sure you have sorl thumbnails configured.

# settings.py
INSTALLED_APPS = (
    # ...
    'async_thumbnail',
    # ...
)

# urls.py
urlpatterns = [
    # ...
    path('', include('async_thumbnail.urls')),
    # ...
]

{% load async_thumbnail %}

<!-- Default -->
<img src="{% async_thumbnail object.image "900x600" crop="center" %}">

<!-- Save as var -->
{% async_thumbnail object.image "900x600" crop="center" as im %}
<img src="{{ im.url }}" width="{{ im.width }}" height="{{ im.height }}">

FetchFromCacheMiddleware

When you use the default full page caching middleware, it may be a good idea to replace it with this middleware. This prevents cache from being updated when the content contains a render URL.

Warning

In case you’re using things like source sets or lazy loading techniques this may be a bad idea.

# settings.py
MIDDLEWARE = (
    'django.middleware.cache.UpdateCacheMiddleware',
    # ...
    'async_thumbnail.middleware.FetchFromCacheMiddleware',
)

ASYNC_THUMBNAIL_ENDPOINT

ASYNC_THUMBNAIL_PATTERN_NAME
