django-dummy-thumbnails 0.1.1

Add dummy_thumbnails to the INSTALLED_APPS:

INSTALLED_APPS = [
    # ...
    'easy_thumbnails',
    'dummy_thumbnails',
    # ...
]

Add dummy thumbnail generator to THUMBNAIL_SOURCE_GENERATORS:

THUMBNAIL_SOURCE_GENERATORS = (
    'dummy_thumbnails.contrib.thumbnailers.easy_thumbnails.source_generators.dummy_thumbnail',
)

If you are using the included images, don’t forget to collect the static files and create a symlink:

./manage.py collectstatic --noinput
./manage.py dummy_thumbnails_symlink_dummy_images

Now the following would work:

{% load thumbnail %}

<img src="{% thumbnail 'None1' 640x480 crop %}" alt="" />
<img src="{% thumbnail 'None2' 480x640 crop %}" alt="" />
<img src="{% thumbnail 'None3' 200x200 crop %}" alt="" />

Add sorl.thumbnail to the INSTALLED_APPS:

INSTALLED_APPS = [
    # ...
    'sorl.thumbnail',
    'dummy_thumbnails',
    # ...
]

Set the dummy thumbnail engine as THUMBNAIL_ENGINE:

THUMBNAIL_ENGINE = 'dummy_thumbnails.contrib.sorl_thumbnail.engines.DummyThumbnailsEngine'

If you are using the included images, don’t forget to collect the static files and create a symlink:

./manage.py collectstatic --noinput
./manage.py dummy_thumbnails_symlink_dummy_images

Now the following would work:

{% load thumbnail %}

{% thumbnail 'None1' "640x480" crop="center" as im %}
    <img src="{{ im.url }}" width="{{ im.width }}" height="{{ im.height }}" />
{% endthumbnail %}

{% thumbnail 'None2' "480x640" crop="center" as im %}
    <img src="{{ im.url }}" width="{{ im.width }}" height="{{ im.height }}" />
{% endthumbnail %}

{% thumbnail 'None3' "200x200" crop="center" as im %}
    <img src="{{ im.url }}" width="{{ im.width }}" height="{{ im.height }}" />
{% endthumbnail %}
