Should TRIM delete *all* whitespace, or just leading/trailing
whitespace? Trim functions usually just remove leading/trailing
whitespace.

You may be able to get away with simply using
{{ story.tease.strip }}
If you need to remove *all* whitespace, not just the
leading/trailing whitespace, you'll have to create your own
filter to do it. However, it's a fairly simple filter process:
import re
from django.template.defaultfilters import stringfilter
from django import template
register = template.Library()
whitespace_re = re.compile(r'\s')
@register.filter(name='remove_whitespace')
@stringfilter
def remove_whitespace(s):
return whitespace_re.sub('', s)
If the above "{{ story.tease.strip }}" doesn't work for some
reason (because "tease" is an object rather than a string, most
likely), you can create a filter out of it the same way, only using
@register.filter(name='strip')
@stringfilter
def strip(s):
return s.strip()
Either of these should then be usable as
{{ story.tease|strip }}
or
{{ story.tease|remove_whitespace }}
