Upload with photo rotate/crop tools and python backend

Reusable web app to work with file and photo uploads.

• contains JS multifile drag and drop upload UI with instant thumbnails and progress bars upload/static/upload.js
• python/PIL backend for upload, cropping, autocrop and rotation of photos
• seamless integration into Django projects
• image cropping UI (uses jQuery)

Thumbnails are generated using imagemagick.

Generic foreign key allows to associate uploads with any content object (user profile, staff profile, message, album, page, gallery, listing). This way uploaded files can be grouped into collections too.

Installation (into a Django project)

To get the latest version from GitHub

pip3 install -e git+git://github.com/fmalina/upload.git#egg=upload

Add upload to your INSTALLED_APPS

INSTALLED_APPS = (
    ...,
    'upload',
)

Configure your settings to suit, see upload/app_settings.py. You can use the collection model provided.

Add the upload URLs to your urls.py

urlpatterns = [
    ...
    url(r'^upload/', include('upload.urls')),
]

Create your tables

./manage.py migrate upload

Usage

Setup a collection

This app supports multiple collections (or your custom model) with multiple files in each collection.

Add files

Drag and drop upload photos and files into your application. Files can have alternative description and are orderable.

Remarks

Upload shines best for sites that need ability to upload photo galleries.

It will automatically shard the storage folder so as to not hit ext3 subfolder limit (~32000 folders).

Included is also a backup management tool to sync/download publicly uploaded files from server to a local machine.

Integration

Simple integration works out of the box.

To upload files for any model taking advantage of generic foreign key, link:

<a href="{% url 'upload_edit' app_label model(lower) object_id %}">Upload</a>

So a profile picture upload link might look like:

<a href="{% url 'upload_edit' 'auth' 'user' request.user.pk %}">Upload</a>

An important view to reuse or use as inspiration in a custom integration is views_post.FilesEditView.

Example settings

import os

APP_ROOT = os.path.abspath(
    os.path.join(os.path.dirname(__file__), '..'))

STATIC_URL = '/static/'
MEDIA_URL = '/media/'
STATIC_ROOT = APP_ROOT + STATIC_URL
MEDIA_ROOT = STATIC_ROOT + 'media/'

Access control

You can control editing access by implementing is_editable_by method on your collection model such as:

def is_editable_by(self, user):
    if user.pk == self.user_id or user.is_staff:
        return True
    return False

The above ensures that a collection is only editable by its user and staff.
