20650	Filter tag accepts escape filter as a parameter	grzesiof@…	nobody	"The docs state that the `filter` tag doesn't work with safe or escape (https://docs.djangoproject.com/en/dev/ref/templates/builtins/#filter).
But because of a bug in the code it does. This piece of the filter implementation is supposed to handle it:

{{{
if getattr(func, '_decorated_function', func).__name__ in ('escape', 'safe'):
            raise TemplateSyntaxError
}}}
(https://github.com/django/django/blob/master/django/template/defaulttags.py#L668)

But because of the way safe and escape are defined, the decorated name is matching the filter name only for safe:
{{{
@register.filter(""escape"", is_safe=True)
def escape_filter(value):

@register.filter(is_safe=True)
def safe(value):
}}}
https://github.com/django/django/blob/master/django/template/defaultfilters.py#L442
https://github.com/django/django/blob/master/django/template/defaultfilters.py#L400

Perhaps the easiest solution would be to alter the escape_filter definition."	Bug	closed	Template system	1.5	Normal	fixed		bmispelon@…	Accepted	1	0	0	0	1	0
