Django-JFU - A Django Library for jQuery File Upload
Django-JFU is designed to simplify the tasks involved in integrating jQuery
File Upload (https://github.com/blueimp/jquery-file-upload) into Django.
Django-JFU assumes very little and leaves the model/view design up to the user.
Other Django - jQuery File Upload implementations are full-featured but
generally serve more as demonstrations than libraries for existing
applications.
If you seek a tool to ease the integration of jQuery File Upload into your
Django application while still having a great degree of freedom, you may find
this package useful.

Installation
pip install django-jfu
.- Add 'jfu' to
INSTALLED_APPS
in your project settings.py file. - Add 'django.template.context_processors.request' and 'django.template.context_processors.static' to
TEMPLATE_CONTEXT_PROCESSORS
in settings.py. - Run
python manage.py collectstatic
.
Usage
Django-JFU provides simple customizable template tags and override-able
templates that do the work of integrating the jQuery File Upload CSS and
JavaScipt and the HTML implementation found in the jQuery File Upload demo.
To place the jQuery File Upload widget in a template, simply insert the
following within it::
{% load jfutags %}
{% jfu %}
Then create a view that will handle the uploaded files.
The URL for the view is expected to be named 'jfu_upload' by default,
although this can be customized (see Customization below).
Here is an example implementation:
In your urls.py
file::
...
url( r'upload/', views.upload, name = 'jfu_upload' ),
# You may optionally define a delete url as well
url( r'^delete/(?P<pk>\d+)$', views.upload_delete, name = 'jfu_delete' ),
In your views.py
file::
import os
from django.conf import settings
from django.urls import reverse
from django.views import generic
from django.views.decorators.http import require_POST
from jfu.http import upload_receive, UploadResponse, JFUResponse
from YOURAPP.models import YOURMODEL
@require_POST
def upload( request ):
# The assumption here is that jQuery File Upload
# has been configured to send files one at a time.
# If multiple files can be uploaded simulatenously,
# 'file' may be a list of files.
file = upload_receive( request )
instance = YOURMODEL( file = file )
instance.save()
basename = os.path.basename( instance.file.path )
file_dict = {
'name' : basename,
'size' : file.size,
'url': settings.MEDIA_URL + basename,
'thumbnailUrl': settings.MEDIA_URL + basename,
'deleteUrl': reverse('jfu_delete', kwargs = { 'pk': instance.pk }),
'deleteType': 'POST',
}
return UploadResponse( request, file_dict )
@require_POST
def upload_delete( request, pk ):
success = True
try:
instance = YOURMODEL.objects.get( pk = pk )
os.unlink( instance.file.path )
instance.delete()
except YOURMODEL.DoesNotExist:
success = False
return JFUResponse( request, success )
Customization
Django-JFU is designed to be very customizable.
The Django-JFU template tag optionally takes two arguments: the name of the
template to load and the name of the URL pointing to the upload-handling
view.::
{% load jfutags %}
{% jfu 'your_fileuploader.html' 'your_uploader_URL_name' %}
A custom template can extend from the master Django-JFU template
jfu/upload_form.html
. There are several blocks which may be overriden for
the purpose of customization:
- JS_OPTS - The options supplied to the jQuery File Upload
fileupload
function. - JS_INIT - The initializing JavaScript
- FILE_INPUT - The file input for the upload form.
The blocks above are most-likely what you will want to override when seeking to
customize. For instance, one would go about adding a few options to the
fileupload function in this manner::
# your_fileuploader.html
{% extends 'jfu/upload_form.html' %}
{% block JS_OPTS %}
autoUpload: true,
maxNumberOfFiles: 5,
sequentialUploads: true,
{% endblock %}
There are several other blocks too:

The included JavaScript and CSS can be updated or suppressed by overriding
these blocks ::
# your_fileuploader.html
{% extends 'jfu/upload_form.html' %}
{% block JS_JQUERY %}
<script src={{STATIC_URL}}/js/my.newer.jquery.js />
{% endblock %}
{% block CSS_BOOTSTRAP %}
{% comment %}
This is already included.
{% endcomment %}
{% endblock %}
or by replacing the static files themselves.
Demo
If you have downloaded from the repository, a simple demo application has been
included in the 'demo' directory.
To test it out, enter the 'demo' directory and run ::
./setup && ./run
Note that virtualenv is required for the demo to function.
