Templatetag for JS merging and compression

**Javascript merging and compression templatetag** One of the most important things for improving web performance is to reduce the number of HTTP requests. This is a templatetag that merges several javascript files (compressing its code) into only one javascript. It checks if this merged file is up to date, comparing modification time with the other javascripts to merge. Usage: {% load jsmerge %} {% jsmerge mergedfile js/file1.js js/file2.js js/file3.js %} The previous code will: 1. Search in `settings.MEDIA_ROOT` for all files passed by parameter. 2. Create a `/path/to/media_root/mergedfile.js` (if it doesn't exist or it's not up to date). This file is a merging plus compression of all javascripts. 3. Return this HTML fragment: `<script type="text/javascript" src="/media_url/mergedfile.js"></script>`

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.

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).

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'])

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.

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)
