django-shorturls ================ A custom URL shortening app for Django, including easy ``rev=canonical`` support. Most code was originally by Simon Willison; see http://simonwillison.net/2009/Apr/11/revcanonical/ for details. Improved slightly and packaged by Jacob Kaplan-Moss. Patches welcome: http://github.com/jacobian/django-shorturls Usage ===== So, you want to host your own short URLs on your Django site: 1. In your settings, define a set of prefixes for short URLs:: SHORTEN_MODELS = { 'A': 'myapp.animal', 'V': 'myapp.vegetable', 'M': 'myapp.mineral' } The keys are string prefixes; they can be any string, actually, but since we're going for short a single character is probably good. Values are the (hopefully-familiar) ``"<app-name>.<model-class>"`` used by Django to identify a model. Remember: ``app-name`` is the (case-sensitive) last bit of your app's name in ``INSTALLED_APPS``, and ``<model-class>`` is your model class's name, lowercased. Make sure your models have a ``get_absolute_url()`` method defined. 2. Wire up the redirect view by adding to your URLconf:: ('^short/', include('shorturls.urls')) 3. If you'd like to quickly link to shortened URLs in your templates, stick ``"shorturls"`` in ``INSTALLED_APPS``, and then in your templates do:: {% load shorturl %} <a href="{% shorturl object %}">...</a> (where ``object`` is a model instance). Alternatively:: {% load shorturl %} {% revcanonical object %} This generates the whole ``<link rev="canonical" href="...">`` tag for you. That's it. If you'd like more control, keep reading. Settings ======== Available settings are: ``SHORTEN_MODELS`` You've seen this one. ``SHORT_BASE_URL`` If defined, the ``shorturl`` and ``revcanonical`` template tags will prefix generated URLs with this value. Use this if you've got a shorter domain name you'd like to use for small URLs. For example, given ``SHORT_BASE_URL = 'http://exm.pl/'``, ``{% shorturl obj %}`` would return something like ``http://exm.pl/AbCd``. ``SHORTEN_FULL_BASE_URL`` The domain to redirect to when redirecting away from the small URL. Again, you'll use this if your short URL base and your "real" site differ. If not defined, the redirect view will try to guess the proper domain by consulting the ``django.contrib.sites`` framework, if installed, or the requested domain, if not.
