Remove self links middleware

This simple middleware replaces all 'a href' links to the current page to the 'span' elements. This very usefule from the usability point of view. For example, user open in bowser page http://svetlyak.ru/blog/, and this middleware will replace all 'a' elements on this page, which refer to the '/blog/'. Because of this, link 'Blog' in the main menu, become a simple 'span'. Next, when user goes to the next page, a post with full comments list ('/blog/123/'), for example, the item 'Blog' in the main menu become a link again! To use this middleware, just add it to the list of middleware classes: MIDDLEWARE_CLASSES = ('utils.middleware.RemoveSelfLinks',)

Django Registration without username

A simple adaptation of RegistrationFormUniqueEmail from django-registration http://code.google.com/p/django-registration to allow users to register without using a username. This works great with the code from this comment: http://www.djangosnippets.org/snippets/74/#c195 to allow users to completely eliminate the need for a username.

Forms splitted in fieldsets

This template tag build a Form splitted in fieldsets. The fieldsets are configured with a second parameter, that is a tuple like the one used in the Admin class in models in the attribute "fields". You pass to the template the form and the tuple and than use them as parameters for the templatetag. You can take a look at the source and modify It to build forms the way you like. It is very useful If you do not like the way Django build forms with the methods as_p, as_ul or as_table and also do not like to write html by hand.

PDF generation directly using HTML

This is an extract of an example for use of "pisa" <http://www.htmltopdf.org> in "django". It shows the easiest way possible to create PDF documents just using HTML and CSS. In "index" we see the definition of the output of a form in which HTML code can be typed in and then on the fly a PDF will be created. In "ezpdf_sample" we see the use of templates and contexts. So adding PDF to your existing Django project could be just a matter of some lines of code.

URL based breadcrumbs

This is a simple URL based breadcrumb filter I'm using on a site I'm currently building. To use it, just throw the code into template-tag file, and simply pass the current url in a page template like so {{ request.get_full_path|breadcrumbs }} As an example of how to style it, wrap it in a unordered list with an id of breadcrumb, and then in your styles use #breadcrumb li { display: inline; }. On a contact form for a site user, this will produce something along the lines of you are here : [home](/) » [users](/users/) » [username](/username/) » contact form Hopefully someone may find it useful.

Extensible exception handling middleware

This exception middleware abstracts the functionality of the builtin exception handling mechanisms, but makes them extensible by inheritance. Just add it (or some subclass) to the top of your active middleware list. You can use this to [make your admin emails more informative](http://www.djangosnippets.org/snippets/631/) or [log errors to a file](http://www.djangosnippets.org/snippets/639/).

Automagically import settings from installed applications

Use this snippet at the end of your main settings.py file to automagically import the settings defined in each app of `INSTALLED_APPS` that begins with `APPS_BASE_NAME`. Set `APPS_BASE_NAME` to the base name of your Django project (e.g. the parent directory) and put `settings.py` files in every app directory (next to the `models.py` file) you want to have local settings in. # works in the Django shell >>> from django.conf import settings >>> settings.TEST_SETTING_FROM_APP "this is great for reusable apps" Please keep in mind that the imported settings will overwrite the already given and preceding settings, e.g. when you use the same setting name in different applications. Props to [bartTC](http://www.djangosnippets.org/users/bartTC/) for the idea.

htmlentities

The built-in escape filter only works with certain characters. It works great in environments where you can declare your charset (UTF-8). However, not everything can handle anything outside of the ASCII charset. This replaces all non-ASCII characters with their encoded value as `&#174;` for ®, for example.

Time ranges like 7-9 p.m.

Template filter to format a start and end time in to a range.

Stop tests at the first failure

**Note**: The `--failfast` argument in Django since version 1.2 does this. Use this snippet for earlier versions. If a large number of your unit tests get "out of sync", it's often annoying to scan through a large number of test failures which overflow the terminal window's scroll buffer. This library strictly stops after the first failure in a doctest suite. If you're testing multiple applications, it also stops after the first test suite with failures in it. So effectively you'll get one failure at a time. This code has been tested with doctests only so far. You can also fetch the latest source from [my repository](http://trac.ambitone.com/ambidjangolib/browser/trunk/test/).

Decorating urlpatterns

One thing I wanted for a while was the ability to basically apply something like @login_required to a bunch of urlpatterns in one go, instead of having to decorate each and every view manually. In this example, the latter two views will always raise a 404.

Breadcrumbs for flatpages

Custom template filter to generate a breadcrumb trail for a flatpage. Say you have a series of flatpages with URLs like /trunk/branch/leaf/ etc. This filter looks at the URL of a given flatpage, figures out which of the leftwards text chunks correspond to other flatpages, and generates a string of anchored HTML. Usage: {% load make_breadcrumb_trail %} {{ flatpage.url|crumbs:flatpage.title }}
