Wiki-like markup for sub templates
I wanted to have the possibility to use a wiki-like markup style in my flatpages for various purposes (embedding images, quoting, etc.) After a few dead ends I came up with this, which is quite nice I think. > It basically takes a named tag, loads the corresponding template, passes in all arguments, renders the template and replaces the named tag with the result. *The markup looks like this:* > [[example:value to pass|option1=somevalue option2=values can have spaces too! without having to put them in quotes option3=some other value]] *This results in:* * Filter tries to load wiki/wiki_example.html * If it is loaded, it passes an WikiElement containing the value and the options to the template, renders it and replaces the tag with the rendered template *In the "wiki/wiki_example.html" template you can use it like this:* {{param.value}} {{param.opts.option1}} Or loop over param.opts.iteritems.

Basic logic filters
Usage: {% if item|IN:list %} The item is in the list. {% endif %} {% if customer.age|LE:18 %} Go play out here. {% endif %} {% if product.price|add:delivery_cost|GT:balance %} Insufficient funds. {% endif %} You've got the idea.

Code syntax highlighting templatetag
Replaces <code> blocks with syntax highlighted code. Use CSS to actually get the colours you want, look at pygments documentation for extracting css for various styles. This snippet has the advantage of falling back on <pre> if anything goes wrong, and attempting to guess the syntax of code, falling back on python.

Logging solution for mod_python/FCGI
The solution is based on [dballanc's snippet](http://www.djangosnippets.org/snippets/420/). Can easily be combined with any of the [SQL tracing solutions](http://www.djangosnippets.org/tags/debug/). You might want to run a separate logging server and redirect your logs there. Please refer to the [logging reference manual](http://docs.python.org/lib/module-logging.html).

filter/search a newforms select widget
Adds a filter input above a select widget that allows live-filtering on the client-side (no ajax) in Firefox. Example: make_fields_searchable(ModelItemForm, { 'publisher': {'set_size': 8}, 'developer': {'set_size': 8}, 'genre': {}, 'platform': {} })

Automatically trim newforms text fields
Makes sure the value a user entered into a a text-based field is automatically trimmed during form cleaning / validation. The 'field' parameter is expected to be a newforms.fields.Field _instance_.Only modifies str and unicode descending values, and passes everything else on untouched. Example: form = form_for_model(Person) make_trimming(form.fields['name'])

AMF Message passing through Middleware
Middleware for communicating with Flash Player via Flashticle and Django. Setup a view at /gateway/math/multiply like so: def multiply(request, m1, m2): return m1 * m2 Then in your Flex/Flash app you call "math.multiply" on a NetConnection pointing to http://domain.com/gateway/ Does not yet support authentication.

CleanCharField
I was about to start an online community but every time you allow people to post something as a comment you never know what they come up to, especially regarding profanities. So I come up with this idea, I put together some code from the old style form validators and the new newform style, plus some code to sanitize HTML from snippet number [169](http://www.djangosnippets.org/snippets/169/), and the final result is a CharField that only accept values without swear words, profanities, curses and bad html. Cheers.

bigger textfields in admin panel
Sometimes a textarea field is to small for usage. I add some JavaScript and CSS to resize all textareas a little dynamically: The JS change the size in dependence text-lengthen. You should store this snippet into a file like this: templates_django/admin/base_site.html

Logging Middleware
This is a simple Logging Middleware that uses the python logging functions. Simply drop this snippet in a file in your project such as `logmw.py` (don't try to call it `logging.py` though), then add the class to MIDDLEWARE_CLASSES in your settings file. (for instance, `'mysite.logmw.LoggingMiddleware'`) Updated 8/25/08: added PhonyLogger class that swallows log messages when logging is disabled, so code doesn't have to care if it's on or not (thanks to goodness for suggesting the idea, though I missed it before)

CSS Preprocessor
Here is a Django view that turns code like this: @variables { $varcolor: #333; } body { color: $varcolor; padding: 20px; } .space { padding: 10px; } .small { font-size: 10px; } #banana(.space, .small) { margin-bottom: 10px; } And turns it into something like this: body { color: #333; padding: 20px; } #banana { padding: 10px; font-size: 10px; margin-bottom: 10px; } .small { font-size: 10px; } .space { padding: 10px; } Notice the variables declaration at the top. The other feature is *extending* - here #banana extends .space and .small. The url.py entry might look something like this: (r'^css/(?P<css>(\w|-)+)\.css$','csspp.csspp'), Here referencing csspp.py in your path (root directory of your site probably). The code also looks for a CSS_DIR setting in your settings file. You will probably want to point straight to your media/css/ directory. **Known problems** * There is now way of extending selectors that are already extending something else. In the example code there is now way to extend #banana since it is already extending .small and .space.
