timeto template filter

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.

isoutc template filter

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.

FuzzyDateTimeField

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.

Language aware template loader

If you try to load a template named filename.LANG.html it will try to load filename.de.html first, then filename.html afterwards (assuming that German is the currently selected language). Usage: Put in a file named langtemplateloader.py under your project, and replace django's default filesystem loader with this in the TEMPLATE_LOADERS section of settings.py: TEMPLATE_LOADERS = ( 'myproject.langtemplateloader.load_template_source', # 'django.template.loaders.filesystem.load_template_source', 'django.template.loaders.app_directories.load_template_source', 'django.template.loaders.eggs.load_template_source', )

Dynamic import from an installed app

This is an example how to dynamically import modules other than `models.py` from installed apps. It allows you to define the full module path just once in `INSTALLED_APPS` in the settings. Using this technique makes it possible to write extensible and reusable apps as mentioned in [Abstract Models and Dynamicly Assigned Foreign Keys](http://djangotricks.blogspot.com/2009/02/abstract-models-and-dynamicly-assigned.html). Probably, it would be great to have some helpers for doing this in django itself. For example: from django.db import models from django.utils import importlib def import_installed(path): """ Imports a module from an installed app >>> import_installed("myapp.forms") <module 'myproject.apps.myapp.forms'> """ app_name, module = path.split(".", 1) app = models.get_app(app_name) return importlib.import_module(app.__name__[:-6] + module) UPDATE: Reported as ticket [#10703](http://code.djangoproject.com/ticket/10703)
