Comment (by jameshfis...@gmail.com):
To update the filters by zanuxzan:
{{{
from django.forms import ChoiceField
from django import template
register = template.Library()
@register.filter(name='field_value')
def field_value(field):
"""
Returns the value for this BoundField, as rendered in widgets.
"""
if field.form.is_bound:
if isinstance(field.field, FileField) and field.data is
None:
val = field.form.initial.get(field.name,
field.field.initial)
else:
val = field.data
else:
val = field.form.initial.get(field.name,
field.field.initial)
if callable(val):
val = val()
if val is None:
val = ''
return val
@register.filter(name='display_value')
def display_value(field):
"""
Returns the displayed value for this BoundField, as rendered in
widgets.
"""
value = field_value(field)
if isinstance(field.field, ChoiceField):
for (val, desc) in field.field.choices:
if val == value:
return desc
return value
}}}
