Managing Google AppEngine datastore maintenance
This code defines a decorator that inform users of your site when the Google AppEngine data store is in read-only mode during maintenance periods. Use it as a decorator on your views that require write access to the data store. @requires_datastore_write def update(request): ... Create a `maintenance.html` Django template (or change the name in the code) with the message that the user will see, something like: This application is currently in maintenance mode and some operations are temporarily unavailable. Thanks for trying back later. Sorry for the inconvenience.

Use MEDIA_URL in flatpages with SSL
This is a copy of [snippet 654](http://djangosnippets.org/snippets/654/), modified to allow dynamic MEDIA_URL, as you might need that for SSL in combination with [snippet 1754](http://djangosnippets.org/snippets/1754/). This is a template filter to enable the use of the MEDIA_URL setting in content from the flatpages database table. It searches for {{ MEDIA_URL }} and replaces it with the current MEDIA_URL added by a context processor. Note: To set up, drop the above code into a file called media_url.py in your templatetags directory in one of your INSTALLED_APPS, and add the filter to your flatpages template like so: {% load media_url %} {{ flatpage.content|media_url:MEDIA_URL }}
