Snippet List
YUI Autocomplete
This snippet allows you to use YUI's autocomplete widget in a easy way. 1. Download YUI (http://developer.yahoo.com/yui/) library and put it into MEDIA folder (in my case I put YUI/build/ directory as base/yui/ in my MEDIA folder) 2. Create lookup view for your autocomplete field. See 'test_ajax_ac' function to see how this lookup view may be built. You have to define JsonResponse somewhere in your files. JsonResponse is taken from: http://www.djangosnippets.org/snippets/154/ 3. Define url for newly created view in urls.py (in usual way) 4. Include necessary .js and .css files in your page (see example in test_ajax.html) 5. Assign widget to a field - see form's __init__ at UserForm in the example. Additional (optional) parameters are: format_result_fname (name of javascript function for formatting results - see YUI docs for examples)), item_select_handler_fname (name of javascript function for handling item select event (see YUI docs)). When using YUI take care about proper skin - you'll possibly need to define wrapper like: `<div class="yui-skin-sam">....</div>` around your html code.

simple string formatting filter
I use this filter quite a bit to keep my templates less cluttered. Instead of: {%if some_variable%}, {{some_variable}}{%endif%} I can write: {{some_variable|format:", %s"}} A common one I use is: {{some_variable|format:"<p>%s</p>"}}

Extended Paginator
Generate a list of page links like: First Prev 1 2 3 *4* 5 6 7 Next Last To use: 1. Put Paginator.py into your app directory 2. Copy pagination.html to your templates directory 3. pass a paginator object to your Context 4. include the pagination.html template on the page you wanted paginated Feel free to send ideas for improvement. If enough people ask, I'll package this as a single app and perhaps even make the template inclusion into a templatetag for even easier use.

Incrementally Return CSV
The first function (ftype_batch) is a view that passes the first part of the CSV filename and a queryset intended to write out to the file. run_batch prepares the HttpResponse for incrementally writing, and write_batch actually writes out the data. The logic in write_batch is custom to what I need done, but as long as the csv writer receives a sequence to write, it should work.

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.

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).
