Does Django have any template tags to generate common HTML markup? For example, I know that I can get a url using
{% url mapper.views.foo %}

Here is a list of all template tags and filters built into Django. Django core doesn't have as much HTML helpers as Rails, because Django contributors assumed that web developer knows HTML very well. As stated by saturdaypalace, it's very unlikely for AJAX helpers to be added to Django, because it would lead to coupling Django with a specific JavaScript library.
It's very easy to write your own template tags in Django (often you need just to define one function, similiar to Rails). You could reimplement most of Rails helpers in Django during a day or two.
