Django Version Viewer

Version Viewer provides Django Admins (with appropriate permission) the ability to view the Python packages and versions used within the project.

This tool can be used in several ways. It provides:

a template tag which inserts a link onto a template. Clicking that link opens up a pop up modal displaying installed Python packages.
a DjangoCMS toolbar entry. When clicked, a popup will display installed Python packages.
a CSV export of installed Python packages.
a queryable endpoint that displays installed Python packages.

You may also configure which users have access to the link and endpoint.

Installation

To install the Django Version Viewer, simply:

pip install django-version-viewer

Add the following to INSTALLED_APPS in settings.py

INSTALLED_APPS = [
    'django_version_viewer'
]

Add django_version_viewer urls and extend `admin/index.html`

Django Version Viewer needs to extend the admin/index.html and append it's urls to your urls.py. In your urls.py add:

admin.site.index_template = 'admin/custom_index.html'
admin.autodiscover()

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

# Note that you can now make a GET request to the route `r'^django_version_viewer/'` to see
# a list of your app's installed pip dependencies returned in JSON.

In your templates/admin/ dir, create a custom_index.html.

<!-- custom_index.html -->
{% extends "admin/index.html" %}

{% load i18n pip_version_viewer_tags %}

{% block content %}
{% show_pip_package_versions %}
{{ block.super }}
{% endblock %}

Django CMS integration

If Django CMS is installed, a new menu item will be added to the CMS Toolbar Page Menu that will allow opening the version viewer popup.

Permissions

You can set your own access permissions on the template tag and route by defining your own Accessor class. This class must have a allow_access method that returns a boolean. By defualt, django_version_viewer only allows superusers access to the route and template tag.

# Django Version Viewer settings:
ACCESSOR_CLASS_PATH = 'mypathto.my.AccessorClass'

# the default class only allows superusers access
django_version_viewer.mixins.SuperuserAccessor
