RadioSelectWithHelpText

A Django form widget which displays help text for individual items in a set of radio buttons. It overrides the RadioSelect widget, adding a small bit of HTML after each <input> element, with the help text for each item. It was developed for a Django Dash project I'm working on (called transphorm.me), so isn't as feature-rich as it could be, but if you have any trouble installing it - or if I've miscopied any of my code in my rush - please let me know.

Parsing Tag decorator

A simple decorator to register a template.Node object as a tag, without the need to write the usual "`token.split_contents()` yatta yatta blatta blatta" function. The decorator should be called with the name of the tag, and an optional `required` named argument in case your tag requires a minimum number of arguments. Please note that all the arguments in the templatetag call will be passed to the node (except the templatetag name and the `for` and `as` keywords) in the order given. Suggestions etc are very welcome, of course =)

DRY template rendering decorator update

Based fully on [snippet 1929](http://www.djangosnippets.org/snippets/1929/) **The update is:** It checks to see the view returns an instance of HttpResponse and returns that rather than trying to render it. This allows you to return something like `HttpResponseRedirect('/')`, or use a normal `render_to_response` to use a different template. *Also updates cleandict as per comment on original snippet* In this case the 'render_template' decorator assumes there is a myview.html template. this keeps things simple and you DRY. Hope it helps.

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?

Load initial form fields from GET parameters

It is often convenient to be able to specify form field defaults via GET parameters, such as /contact-us/?reason=Sales (where "reason" is the name of a form field for which we want a default value of "Sales"). This snippet shows how to set a form's initial field values from matching GET parameters while safely ignoring unexpected parameters.

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)
