A Django app to export a database dump and media files

This app provides a few views to export the database and the media-root. Default templates are provided for an easy integration with django.contrib.admin.

Currently mysql and sqlite3 database backends are supported.

Additionally the app provides some Amazon S3 integration. Exporting a database dump directly to S3 and listing the bucket contents is implemented.

I originally posted the views on djangosnippets a few month ago here

Installation

Add the folder export to your Python-Path.

Then add export to your INSTALLED_APPS setting:

INSTALLED_APPS = (
    ...
    'export',
)

Then hook the app into your url-conf, for example diretly under the admin url-space:

urlpatterns += patterns('',
    url(r'^admin/export/', include('export.urls')),
)


Be sure to add this pattern before the django.contrib.admin pattern,
otherwise your urls will never be picked up, because they are catched by
the ``r'^admin/(.*)'`` pattern.

Now add Links to the export views to your Admin Index Template, or anywhere else you like. The Links to the views are accessible via:

Export Database: {% url export_database %}
Export Database to S3: {% url export_database_s3 %}
Export Media Root: {% url export_mediaroot %}
List S3 Bucket: {% url export_list_s3 %}

Settings

There are currently two optional settings:

MYSQLDUMP_CMD : The command used to dump a mysql database.
                Defaults to: '/usr/bin/mysqldump -h %s --opt --compact \
                --skip-add-locks -u %s -p%s %s | bzip2 -c'

SQLITE3DUMP_CMD: The command used to dump a sqlite2 database.
                 Defaults to: 'echo ".dump" | /usr/bin/sqlite3 %s | bzip2 -c'

DISABLE_STREAMING: Normally an exported file would get streamed to the client
                   in small chunks. If you are using ConditionalGetMiddleware
                   or GZipMiddleware, this will break the streaming and
                   results in zero-byte-size files. Set this option to
                   ``True`` will disable streaming.

                   Keep in mind that, in this case, the exported file
                   will held entirely in RAM until it's fully transmitted
                   to the client. Defaults to: ``False``

                   See http://code.djangoproject.com/ticket/7581 for details.

To enable Amazon S3 support there are two steps:

  • first install the S3 python library (can be found on the amazon website)
  • then add a few settings with your credentials:
    • settings.AWS_ACCESS_KEY_ID
    • settings.AWS_SECRET_ACCESS_KEY
    • settings.AWS_BUCKET_NAME
