Django: sorl-thumbnail and easy-thumbnail in same project

Question

I'm working on and project that uses two separate modular Django apps. However, one app requires easy-thumbnails and the other requires sorl-thumbnails. Unfortunately, the two thumbnail libraries make use of the template tag syntax {% load thumbnail %}, so they clash and break when a template using them tries to render.

Are there any approaches to solve this type of clash? (For example, a template option does to the effect of {% load thumbnail as easy_thumbnail %}). Am I going to have to fork one of the apps and replace one of the thumbnail libraries with another? If so, which should I choose to go with?

Thank you for considering my question, Joe

Answer 1

In Django 1.9, you can use the libraries option of DjangoTemplates to include a tag library under a specified name. In the example below, the thumbnail library from sorl.thumbnail is included under the name sorl_thumbnail.

Note: the templatetag itself is not changed within the template... ie. remains thumbnail

Usage:

settings.py

TEMPLATES = [
    {
        'BACKEND': 'django.template.backends.django.DjangoTemplates',
        'DIRS': [os.path.join(BASE_DIR, "foo", "templates")],
        'APP_DIRS': True,
        'OPTIONS': {
            'context_processors': [
                'django.template.context_processors.debug',
                'django.template.context_processors.request',
                'django.contrib.auth.context_processors.auth',
                'django.contrib.messages.context_processors.messages',
            ],
            'libraries': {
                'sorl_thumbnail': 'sorl.thumbnail.templatetags.thumbnail',
            },
        },
    },
]

your_template.html

{% load sorl_thumbnail %}
{% thumbnail mymodel.image "640x480" crop="center" as im %}
    <img src="{{ im.url }}" width="{{im.width}}" height="{{im.height}}"/>
{% endthumbnail %}
