Simple login script from a nub

The utility of a login script is self-evident. As I learned about Django's built-in user authentication features, I whipped up this script and figured that I'd post it here. I am by no means an expert and would appreciate any constructive criticism. However, per the rules of this site, this is working code and not work in progress. Thanks Also: I wrote a blog post explaining the script for those who are interested: http://bit.ly/bwIL

Test if sessions are working

I wasn't sure if my setup supported sessions properly. This view helped me make sure. Usage: fill the inputs with text and make sure that these values traverse a couple of requests. If it doesn't work then maybe the session backend you've set is broken?

Management command decorator

A quick-and-dirty, and extremely simple, decorator to turn a simple function into a management command. This still requires you to have the management directory structure, but allows you to name your primary method whatever you want, and encapsulates the basic functionality of an argument-accepting management commmand. The function's docstring will be used for the command's help text if the `help` arg is not passed to the decorator. Simple usage: from myapp.utils import command @command() def my_command(): print "Hello, world" I'm not too familiar with the intricacies of decorators and management commands, so this could probably (most likely) be improved upon, but it's a start. **Update**: I've taken this a bit farther and put my work up on bitbucket: https://bitbucket.org/eternicode/django-management-decorators/src

File storage with a better rename method

A file storage which uses a more sane rename method for existing files. Add `DEFAULT_FILE_STORAGE = 'site.storage.BetterNameFileSystemStorage'` (obviously changing `site.storage` to the module which you put this inside)

pyserver -- runserver alias

I use Django's built-in development server all the time, but get tired of typing out the command to run it, and if I'm testing some custom admin css/js, I *really* get tired of typing out the command that correctly directs the middleware to use my admin media dir. So I added this alias to my .bashrc and when I'm in a project's root, I just type 'pyserver' and the development server fires up, automatically passing an --adminmedia arg if I have some custom admin media for the project (otherwise it's 'runserver' as always). Note: This relies on the convention that my custom admin media will be in a folder called admin_media that resides at the project's base. Of course, change it to whatever convention you use. I'm not a bash expert or anything, but this works for me ;)

NonceField for disabling autocompletion

For disabling autocomplete and security purpose, this snippet defines a CharField with a randomness name for each request of the form. This is useful for turning off autocomplete for credit card input in all browsers, without breaking the xhtml validation. * [https://wiki.mozilla.org/The_autocomplete_attribute_and_web_documents_using_XHTML#Security](https://wiki.mozilla.org/The_autocomplete_attribute_and_web_documents_using_XHTML#Security) * [http://en.wikipedia.org/wiki/Cryptographic_nonce](http://en.wikipedia.org/wiki/Cryptographic_nonce)

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 `®` for ®, for example.

admin filters as select boxes

This templatetag let's you output a form with select boxes instead of the ul's for filters. Uses some hacks to get the param names out of query strings. This would be a lot easier if filterspecs defined params instead of query strings (if filter tag would handle the encoding)

CustomChoiceField, Selectable label field version of ModelChoiceField

**The problem** ModelChoiceField always uses __unicode__ or __str__ to fill the labels. I needed to dynamically select which field to use for the labels. **The solution** My approach copies a lot from [this blog](http://oebfare.com/blog/2008/feb/23/overriding-modelchoicefield-labels/) with some modifications to make it more dynamic. There are some proposals to fix on this [Ticket #4620]( http://code.djangoproject.com/ticket/4620) **How to use** Include the code on your forms.py (or whatever you are using) and use the CustomChoiceField with the extra argument label_field instead of ModelChoiceField. Hope it helps someone.
