FuzzyDateTimeField is a drop in replacement for the standard [DateTimeField](http://docs.djangoproject.com/en/dev/ref/forms/fields/#datetimefield) that uses [dateutil.parser](http://labix.org/python-dateutil#head-a23e8ae0a661d77b89dfb3476f85b26f0b30349c) to clean the value. It has an extra keyword argument `fuzzy=True`, which allows it to be more liberal with the input formats it accepts. Set `fuzzy=False` for more strict validation.

Use this template filter to produce an ISO format UTC datetime string from a [timezone aware](http://docs.python.org/library/datetime.html#datetime.tzinfo) [datetime](http://docs.python.org/library/datetime.html#datetime.datetime) object. Usage example in a template: `<input name="when" type="hidden" value="{{ dt|isoutc }}"`. You must have [dateutil](http://labix.org/python-dateutil) installed for `tz.tzutc()` to work. And of course, you'll need to load it as a [custom tag](http://docs.djangoproject.com/en/dev/howto/custom-template-tags/#howto-custom-template-tags) to use it. The output format differs from python's [datetime.isoformat](http://docs.python.org/library/datetime.html#datetime.datetime.isoformat) by ignoring the `microsecond` and including a "Z" suffix for the UTC timezone. For ease of use, it is also not double quoted as the standard suggests.
This is a more compact version of django's [timeuntil](http://docs.djangoproject.com/en/dev/ref/templates/builtins/#timeuntil) filter that only shows hours & minutes. If used like `{{ dt|timeto }}`, will produce output like "1hr 30min". If you know for sure that the server has the same timezone as the [datetime](http://docs.python.org/library/datetime.html#datetime-objects) value, then you don't need [datetutil.tz](http://labix.org/python-dateutil#head-587bd3efc48f897f55c179abc520a34330ee0a62) for utc time conversion.
give diggbar users something to think about (http://daringfireball.net/2009/04/how_to_block_the_diggbar)
This is based on snippets 29 and 43, both of which had good ideas, and I thought, "why not combine them?" Given the new_topic string above, the resulting slug will be: "test-long-string-which-has-many-words-here" John Crawford Note - requires python 2.5, for list comprehensions. Otherwise you could just use a for loop to build the clean_list.
This piece of code allows the quickly set the locale to a different language. This can be used for instance in cron jobs to send emails to users in their specific language. This is pretty rough code, it be better to create an object, having two functions: set_locale and reset_locale. set_locale would than contain steps 1 to 4 (and return the request object on succes), reset_locale would be step 6 Enjoy!
This snipped get the latest rss links from delicious from a DELICIOUS_USER that you have to define in your settings. I use this snippet in the [trespams code blog](http://trespams.com) to inform the visitor about the last links I have bookmarked. This is a modified version of [snipped 819](http://www.djangosnippets.org/snippets/819/) to allow using any variable in the template to obtain the results. It also added a 6 hours caché for the rss.
Slightly shonky implementation of a custom URL shortening view, as [described on my blog](http://simonwillison.net/2009/Apr/11/revcanonical/). Depends on [baseconv.py](http://www.djangosnippets.org/snippets/1431/)
usage: {{ object.content|wordbreak:"10" }} This means if any word is 10 characters or longer, a `­` will be placed every 10 characters. This is to break long words which may break the appearance of a page. The output of this is HTML safe as the content has been conditionally escaped.
While working on my website projects today I had the idea to use HTML/JS instead of a IP database to localize the dates and times shown on the websites. Here are the snippets to use the JS snippets as filters for Django running on Google App Engine. You can use those filters on datetime objects.
If you want to do your own JSON serialization of [datetime](http://docs.python.org/library/datetime.html#datetime.datetime) objects instead of using DjangoJSONEncoder, use `simplejson.dumps(o, default=encode_datetime)`. The `encode_datetime` method will convert the datetime object to UTC and output an ISO format string just like the [isoutc template filter](http://www.djangosnippets.org/snippets/1424/).
If you have JSON objects with `datetime` attributes that you want to decode to python [datetime](http://docs.python.org/library/datetime.html#datetime.datetime) objects, you can use `decode_datetime` as a [simplejson](http://simplejson.googlecode.com/svn/tags/simplejson-2.0.9/docs/index.html) object hook. `simplejson.loads(s, object_hook=decode_datetime)`.
Based on [svetlyak](http://www.djangosnippets.org/users/svetlyak/)'s [nofollow filter](http://www.djangosnippets.org/snippets/312/). This one processes only external URL's. Links with internal URL's will be returned unmodified. There's one gotcha; I preferred to have false positives instead of false negatives. So, it will nofollow `href="some/relative/path/"` for example. If you must do relative paths do it like this: <a href="./some/relative/path">link text</a>
Example mixin for creating and removing thumbnails on a model. Also adds some methods for accessing an url for an image size. It might be a better idea to use a custom image field instead of this approach. Idea for getting the image url for different sizes from http://code.google.com/p/django-photologue Example usage <pre> >>> p.get_small_image_url() u'http://127.0.0.1:8000/site_media/photos/small_someimage.jpg' </pre>
