Comment (by mitar):
Maybe I am wrong. This simple version works quite nicely:
{{{
@register.simple_tag
def urltemplate(viewname):
urlconf = urlresolvers.get_urlconf()
resolver = urlresolvers.get_resolver(urlconf)
prefix = urlresolvers.get_script_prefix()
possibilities = resolver.reverse_dict.getlist(viewname)
if len(possibilities) != 1:
# TODO: Template tags should not the throwing exceptions (only if
TEMPLATE_DEBUG is true)
raise NotImplementedError
possibility, pattern, defaults = possibilities[0]
if len(possibility) != 1:
# TODO: Template tags should not the throwing exceptions (only if
TEMPLATE_DEBUG is true)
raise NotImplementedError
result, params = possibility[0]
for param in params:
result = result.replace('%%(%s)s' % param, '{%s}' % param)
return prefix + result
}}}
