By default all forms created using inlineformset_factory are displayed as tables (because there is only a .as_table method) and there are no .as_p or .as_ul methods in them, so you need to do that by hand.
The proper looking email links rendered to the browser are not in the source code that way, and are rendered by javascript, so robots can't extract it. Its a trick way to have the email displayed properly without getting spamed as a result. Unless the robots are getting smarter, this has worked for me thus far.

Django tagging by default doesn't provide a templatetag to get the related objects for another object. Even though this is implemented as a model. Still, one can use the existing templatetags to achieve the same outcome. Of course, writing a custom templatetag would be more efficient in terms of database access.
As a quick, simple way to take a list of items make a table with n items per row I added a custom template filter for modulo of an integer. To make the custom filter first create a "templatetags" directory in your application folder then add an empty file called "__init__.py" in that new directory. Finally add a file "myapp_tags.py" with the above code in it. In the template you load your custom filter with {% load pictures_tags %} and then you can make a table with n elements per row using a simple for loop and in if statement. This works because if ( for_loop.counter modulo n ) is zero ("if not" evaluates to True on zero values), then it makes a new table row. You might note that if the number of items in list is a multiple of n, there will be an empty row at the end... preventing that adds needless complexity so I left that out!
All you need to do is include the file you save this as in your other templates. The css and javascript is right in the file. Fully customizable. Very easy. Click a date to choose a single date. Click a second date to choose a range. A third click will act as a first click. note: you also will want to customize the django template specific variables in elements with ids: s_date e_date cal_month if you change those, it's not even really django specific, but i use this in my form for time off requests at work.

JavaScript template for [GoogleAdmin](http://www.djangosnippets.org/snippets/1144/). Also requires the [google.html](http://www.djangosnippets.org/snippets/1145/) template. Install in `gis/admin` somewhere in your template path.
HTML template for [GoogleAdmin](http://www.djangosnippets.org/snippets/1144/). Also requires the [google.js](http://www.djangosnippets.org/snippets/1146/) template. Install in `gis/admin` somewhere in your template path.
You can place this code above your form and it will list out all errors in your form if there are errors. Sometimes I like listing the errors at the top of the form because I think it looks cleaner. Make sure you add error_messages={'required': 'My detailed error here'} in your view.py for your form.
This is a fairly small bit template that, if placed in your_project_dir/templates/admin/prepopulated_fields_js.html will override the template that is normally pulled by the preopulated fields templatetag in the admin. The result is that you can successfully specify a ForeignKey or other field involving choices as a source for prepopulate_from in your admin.py. It works just as well when there are multiple fields of both the text and choice variety.
This snippet uses the [django-environment project](http://code.google.com/p/django-environment/). Django-environment is used to provide "environment variables" to django apps.
Extension of the idea from [WuzHere example from Google IO](http://code.google.com/p/wuzhere/) about creating one compressed js or css file. Original code used not very elegant if statements. I've changed it to template tags. On production server it will also use current version id. Insert code in *cssjs.py* file in *templatetags* dir in your application and use as below (more details in docs): `<script type="text/javascript" src="/media/jsmergefile.js"></script>` **This code does not compress CSS and JS on the fly, because GAE is read-only and using Datastore is too heavy.**
