Automate unique slugs

If you want unique values for a slug field, but don't want to bother the user with error messages, this function can be put into a model's save function to automate unique slugs. It works by appending an integer counter to duplicate slugs. The item's slug field is first prepopulated by slugify-ing the source field. If that value already exists, a counter is appended to the slug, and the counter incremented upward until the value is unique. For instance, if you save an object titled Daily Roundup, and the slug daily-roundup is already taken, this function will try daily-roundup-2, daily-roundup-3, daily-roundup-4, etc, until a unique value is found. Call from within a model's custom save() method like so: `unique_slug(item, slug_source='field1', slug_field='field2')` where the value of field slug_source will be used to prepopulate the value of slug_field. Comments appreciated!

send_mail wrapper with DEBUG email trapping

By using this simple wrapper instead of Django's default send_mail function, you gain the peace of mind of knowing that when settings.DEBUG == True, all the emails will be sent to you instead of the original recipient. Handy for testing.

Restrict Middleware

This is a _very basic_, _easily foolable_, restriction method implemented in a Django middleware. However, for low security sites that need a cursory barrier to entry (without the ability to assign/administer user accounts), this does very well. All of the features are fairly well-documented in the code.

  • restrict

Auth decorators with 403

These decorators are based on user_passes_test and permission_required, but when a user is logged in and fails the test, it will render a 403 error instead of redirecting to login - only anonymous users will be asked to login.

  • user_passes_test
  • 403

Command Line Script Launcher

I often write short test or development scripts that are intended as one-offs. I typically want to execute these scripts from the command line but am always forgetting the necessary steps to set up the Django environment [as described here][bennett]. This snippet allows you execute arbitrary Python scripts from the command line with the context of a given project: python manage.py execfile /path/to/some/script.py Add the code to a file named `execfile.py` within the `management/commands` directory of one of your apps ([see here][ref] for details).

Stateful paginator, digg style

**This code will throw deprecation warnings in newer Django checkouts - see the http://www.djangosnippets.org/snippets/773/ for an improved version that should work with the recent trunk.** objects = MyModel.objects.all() paginator = DiggPaginator(objects, 10, body=6, padding=2, page=7) return render_to_response('template.html', {'paginator': paginator} {% if paginator.has_next %}{# pagelink paginator.next #}{% endif %} {% for page in paginator.page_range %} {% if not page %} ... {% else %}{# pagelink page #} {% endif %} {% endfor %} http://blog.elsdoerfer.name/2008/03/06/yet-another-paginator-digg-style/

Prettify HTML body contents in HTTP response

This is an enhancement of snippet [#172](http://djangosnippets.org/snippets/172/). Here I use [BeautifulSoup](http://www.crummy.com/software/BeautifulSoup/) — far more easier to install through pip in a virtualenv, and possibly a bit more maintained — to format and properly indent the rendered HTML from templates. I also added a check to only tidy contents in a `DEBUG=True` environment, regarding high impact on performance while doing so in production. Last, it's compatible with Django 1.2.x.
