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 %}
Original idea from this stackoverflow answer

from django import template
from django.contrib.contenttypes.models import ContentType
register = template.Library()
@register.filter
def content_type(obj):
if not obj:
return False
return ContentType.objects.get_for_model(obj)
