Tests
-----
The tests should run with tox. Running `tox` will run all tests for all environments.
However, it is possible to run a certain environment with `tox -e `, a list of all environments
can be found with `tox -l`. These tests require the dependencies of the different engines defined in
the documentation. It is possible to install these dependencies into a vagrant image with the
Vagrantfile in the repo.User Support
============If you need help using sorl-thumbnail browse https://stackoverflow.com/questions/tagged/sorl-thumbnail
and posts your questions with the `sorl-thumbnail` tag.How to Use
==========Get the code
------------Getting the code for the latest stable release use 'pip'. ::
$ pip install sorl-thumbnail
Install in your project
-----------------------Then register 'sorl.thumbnail', in the 'INSTALLED_APPS' section of
your project's settings. ::INSTALLED_APPS = [
'django.contrib.admin',
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.messages',
'django.contrib.staticfiles','sorl.thumbnail',
]Templates Usage
---------------All of the examples assume that you first load the thumbnail template tag in
your template.::{% load thumbnail %}
A simple usage. ::
{% thumbnail item.image "100x100" crop="center" as im %}
{% endthumbnail %}See more examples in the section `Template examples`_ in the Documentation
Model Usage
-----------Using the ImageField that automatically deletes references to itself in the key
value store and its thumbnail references and the thumbnail files when deleted.
Please note that this is only compatible with django 1.2.5 or less.::from django.db import models
from sorl.thumbnail import ImageFieldclass Item(models.Model):
image = ImageField(upload_to='whatever')See more examples in the section `Model examples`_ in the Documentation
Low level API
-------------You can use the 'get_thumbnail'::
from sorl.thumbnail import get_thumbnail
from sorl.thumbnail import deleteim = get_thumbnail(my_file, '100x100', crop='center', quality=99)
delete(my_file)See more examples in the section `Low level API examples`_ in the Documentation
Using in combination with other thumbnailers
--------------------------------------------Alternatively, you load the templatetags by {% load sorl_thumbnail %}
instead of traditional {% load thumbnail %}. It's especially useful in
projects that do make use of multiple thumbnailer libraries that use the
same name (``thumbnail``) for the templatetag module::{% load sorl_thumbnail %}
{% thumbnail item.image "100x100" crop="center" as im %}
{% endthumbnail %}Frequently asked questions
==========================Is so slow in Amazon S3!
------------------------Possible related to the implementation of your Amazon S3 Backend, see the `issue #351`_
due the storage backend reviews if there is an existing thumbnail when tries to
generate the thumbnail that makes an extensive use of the S3 APIA fast workaround if you are not willing to tweak your storage backend is to set::
THUMBNAIL_FORCE_OVERWRITE = True
So it will avoid to overly query the S3 API.
