Template filter that divides a list into exact columns

Template filter that divides a list into an exact number of columns. The number of columns is guaranteed. Example (list == [1,2,3,4,5,6,7,8,9,10]): {% for column in list|columns:3 %} <ul> {% for item in column %} <li>{{ item }}</li> {% endfor %} </ul> {% endfor %} Result: <ul> <li>1</li> <li>2</li> <li>3</li> <li>4</li> </ul> <ul> <li>5</li> <li>6</li> <li>7</li> </ul> <ul> <li>8</li> <li>9</li> <li>10</li> </ul> By Davide Muzzarelli

ModelList class

This class makes easier the job of rendering lists of model instances in django templates. It's intended to mimic the behavior of the Model Forms in that it contains the code needed to render it as an HTML table and makes it easy to handle all the model lists from a single view (as it's usually done with the generic views for creating and updating model instances). It also supports pagination and provides hooks for subclassing and customizing the rendered fields, column titles and list order. Basic example: `class Account(Model):` `name = models.CharField(max_length=MAX_LENGTH)` `responsible = models.CharField(max_length=MAX_LENGTH)` `email = models.EmailField()` `class AccountModelList(ModelList):` `class Meta:` `model = Account` `fields = ['name', 'responsible'] #email won't get a column` The model list would be instantiated with something like: `model_list = AccountModelList(instances=account_queryset)` Then a table header can be rendered with model_list.as_table_header(), while the table rows can be rendered calling as_table() on each model_list.items element.

JavaScript implementation of Python xrange() builtin

I don't like not having the `range()/xrange()` in JavaScript &mdash; particularly when working with [Underscore.js](http://documentcloud.github.com/underscore/) and other such libraries &mdash; so I wrote it. It's not rocket science, but it might help make the world a slightly less annoying place for a couple of people.

CountryField (UN Country List, 3 Char Codes)

**Adapted from** [CountryField](http://www.djangosnippets.org/snippets/494/) - **Initial thanks to marinho** Uses the UN country list listed in the source - this provides the 3 character ISO country code. Ordered by display value and not country code. Just place anywhere you like and import CountryField to use. `country = CountryField(verbose_name="Country", help_text="The registrant's country of residence.")`
