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 JQuery Calendar in ModelForm
The important code really is just setting up the base site to use jquery and then using the javascript function to show the calendar on a widget with the .vDateField class set. The DateField modeltype automatically gets the css class .vDateField when using ModelForms.

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 }}
