django-medusa Description

django-medusa is a Django app that allows rendering a Django-powered website into a static website a la Jekyll, Movable Type, or other static page generation CMSes or frameworks. django-medusa is designed to be as simple as possible and allow the easy(ish) conversion of existing dynamic Django-powered websites -- nearly any existing Django site installation (not relying on highly-dynamic content) can be converted into a static generator which mirror's that site's output.Given a "renderer" that defines a set of URLs (see below), this uses Django's built-in TestClient to render out those views to either disk, Amazon S3, or to Google App Engine.At the moment, this likely does not scale to extremely large websites.Optionally utilizes the multiprocessing library to speed up the rendering process by rendering many views at once.For those uninterested in the nitty-gritty, there are tutorials/examples in the docs dir:- Tutorial 1: Hello WorldRenderer classesRenderers live in renderers.py in each INSTALLED_APP.Simply subclassing the StaticSiteRenderer class and defining get_paths works:from django_medusa.renderers import StaticSiteRendererclass HomeRenderer(StaticSiteRenderer): def get_paths(self): return frozenset()renderers = A more complex example:from django_medusa.renderers import StaticSiteRendererfrom myproject.blog.models import BlogPostclass BlogPostsRenderer(StaticSiteRenderer): def get_paths(self): paths = items = BlogPost.objects.filter(is_live=True).order_by('-pubdate') for item in items: paths.append(item.get_absolute_url()) return pathsrenderers = Or even:from django_medusa.renderers import StaticSiteRendererfrom myproject.blog.models import BlogPostfrom django.core.urlresolvers import reverseclass BlogPostsRenderer(StaticSiteRenderer): def get_paths(self): # A "set" so we can throw items in blindly and be guaranteed that # we don't end up with dupes. paths = set() items = BlogPost.objects.filter(is_live=True).order_by('-pubdate') for item in items: # BlogPost detail view paths.add(item.get_absolute_url()) # The generic date-based list views. paths.add(reverse('blog:archive_day', args=( item.pubdate.year, item.pubdate.month, item.pubdate.day ))) paths.add(reverse('blog:archive_month', args=( item.pubdate.year, item.pubdate.month ))) paths.add(reverse('blog:archive_year', args=(item.pubdate.year,))) # Cast back to a list since that's what we're expecting. return list(paths)renderers = Renderer backendsDisk-based static site rendererExample settings:INSTALLED_APPS = ( # ... # ...

The app.yaml file contains the URL mappings to upload the entire site as a static files.App Engine generally follows filename extensions as the mimetype. If you have paths that don't have an extension and are not HTML files (i.e. "/foo/json/", "/feeds/blog/", etc.), the mimetype from the "Content-Type" HTTP header will be manually defined for this URL in the app.yaml path.Usage1. Install django-medusa into your python path (TODO: setup.py) and add django-medusa to INSTALLED_APPS.2. Select a renderer backend (currently: disk or s3) in your settings.3. Create renderer classes in renderers.py under the apps you want to render.4. django-admin.py staticsitegen5. ???6. Profit!ExampleFrom the first example in the "Renderer classes" section, using the disk-based backend.$ django-admin.py staticsitegenFound renderers for 'myproject'...Skipping app 'django.contrib.syndication'...
