## How to use
Use this [admin filter](https://docs.djangoproject.com/en/1.8/ref/contrib/admin/#django.contrib.admin.ModelAdmin.list_filter) together with a numeric field to allow filtering changlist by field
values range (in this case, age groups):
For example, to group customers by age groups:
class Customer(models.Model):
# ...
age = models.IntegerField()
age.list_lookup_range = (
(None, _('All')),
([0, 2], '0-2'),
([2, 4], '2-4'),
([4, 18], '4-18'),
([18, 65], '18-65'),
([65, None], '65+'),
))
class CustomerAdmin(admin.ModelAdmin):
list_filter = [('age', ValueRangeFilter), ]
## Inspiration
[This snippet](https://djangosnippets.org/snippets/587/) (for django < 1.4) inspired me to make this work for newer django versions.
Render a given instance of collections.Counter into a 2 column html table.
Optionally accepts `column_title` keyword argument which sets the table
key column header.
Usage:
{% counter_table event_counter column_title='event type' %}
The above will render the a table from the `event_counter` variable with the first (key) column set to "event type".
See below for an example template (i.e `counter_table.html`)
{% load i18n %}
<table>
<thead>
<tr>
<th>{{column_title|capfirst}}</th>
<th>{% trans "count"|capfirst %}</th>
</tr>
</thead>
<tbody>
{% for key, count in most_common %}
<tr>
<td>{{key}}</td>
<td>{{count}}</td>
</tr>
{% endfor %}
</tbody>
<tfoot>
<tr>
<td>{% trans "total"|capfirst %}</td>
<td>{{total_count}}</td>
</tr>
</tfoot>
</table>

Custom template filter to retrieve a content type of a given model instance. Useful for ModelForms which want to set the content_type field (i.e: GenericForeignKey).
### A usage example:
{% load helpers %}
{% with instance|content_type as ctype %}
<input type="hidden" name="content_type" value="{{ ctype.pk }}">
{% endwith %}
