In #24133 was added deprecation warning when `self.success_url` contains
old %-style Python formatting strings.
However, `success_url` could be a lazy object like `reverse_lazy` and
trying to call `re.search` on lazy object results in `TypeError`:
{{{
../../../../.envs/lingui-next/lib/python3.4/site-
packages/django/views/generic/edit.py:166: in get_success_url
if re.search(r'%\([^\)]+\)', self.success_url):
_ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _
_ _ _
pattern = '%\\([^\\)]+\\)'
string = <django.utils.functional.lazy.<locals>.__proxy__ object at
0x10678ca90>
flags = 0
def search(pattern, string, flags=0):
"""Scan through string looking for a match to the pattern,
returning
a match object, or None if no match was found."""
> return _compile(pattern, flags).search(string)
E TypeError: expected string or buffer
../../../../.envs/lingui-next/lib/python3.4/re.py:166: TypeError
}}}
