Gets the list element at the given index **Example** {% for item1 in list1 %} <p>List1 element: {{ item1 }}</p> <p>List2 element: {{ list2|get_at_index:forloop.counter0 }} {% endfor %}
Template filter that truncates the text when it exceeds a certain number of characters. It deletes the last word only if partial. Adds '...' at the end of the text, only if truncated. Examples (text == 'Lorem ipsum dolor sit amet', len(text) == 26) {{ text|truncatewords_by_chars:30 }} 'Lorem ipsum dolor sit amet' {{ text|truncatewords_by_chars:25 }} 'Lorem ipsum dolor sit...' {{ text|truncatewords_by_chars:21 }} 'Lorem ipsum dolor sit...' {{ text|truncatewords_by_chars:20 }} 'Lorem ipsum dolor...'

Template filter that divides a list into an exact number of columns. The number of columns is guaranteed.

Often I want to call a custom manager method in the template, something like Snippet.objects.get_latest(). I hate writing custom templatetags to do all that work, so instead I've written a filter that will work for any. Here's how I use it: {% for snippet in "cab.snippet"|call_manager:"top_rated"|slice:":5" %}
Nicely output all form errors in one block, using field labels rather than the field attribute names.
Improved version of my snippet #1346. Now works correctly with multiple usernames and hash tags. Both twitter usernames and hashtags are converted into links to twitter profiles and twitter search. Updated, forgot about underscores in usernames.
A filter that changes a preparsed date from [Ultimate Feedparser](http://www.feedparser.org/) to a regular datetime instance. Now you can -for example- pass a feed parsed by feedparser to a template and do this: {% for item in feed.entries %} Title: {{ item.title }}<br /> Date: {{ item.updated_parsed|feedparsed|date:"Y-m-d" }} {% endfor %}
A template filter which returns "a" or "an" depending on the phonetic value of given text.
Generate QR Code image from a string with the Google charts API http://code.google.com/intl/fr-FR/apis/chart/types.html#qrcodes Exemple usage in a template {{ my_string|qrcode:"my alt" }} will return the image tag with * src: http://chart.apis.google.com/chart?chs=150x150&cht=qr&chl=my_string&choe=UTF-8 * alt: my alt"
Couldn't get the original to work, and wanted more functionality (scale on x or y coordinates) <img src="{{ object.image.url }}" alt="original image"> <img src="{{ object.image|thumbnail:"250w" }}" alt="image resized to 250w x (calculated/scaled)h "> <img src="{{ object.image|thumbnail:"250h" }}" alt="image resized to (calculated/scaled)w x 250h h "> <img src="{{ object.image|thumbnail:"250x200" }}" alt="image resized to 250wx200h "> <img src="{{ object.image|thumbnail }}" alt="image resized to default 200w (or whatever you default it to) format"> Original http://www.djangosnippets.org/snippets/192/ Adapted http://www.djangosnippets.org/snippets/955/ Sampled From: http://batiste.dosimple.ch/blog/2007-05-13-1/ http://vaig.be/2008/05/17/stdimagefield-improved-image-field-for-django/
A couple of useful template filters for splitting a list (or QuerySet) up into rows or columns.
UPDATED: This now supports an argument for the initial header level. This is a modified version of `django.contrib.markup` that allows you to highlight code via [pygments](http://pygments.pocoo.org/). The code block can be used as: `Here's a paragraph, and a code example: .. code:: language *insert code here* continue with your normal document.` Setup: Insert the snippet into `mysite/templatetags/rest.py`, then add `mysite` to your installed apps in `settings.py`. In your template, `{% load rest %}` and `{{ mycontent|rest }}`.
