-----------------------------+---------------------------------
If you define a view `v2` like this:
{{{
def view(request):
pass
v1 = functools.partial(view)
v2 = functools.partial(v1)
}}}
then set `v2` as the view for some url, then you'll get an attribute error
if you try reverse() on it :
AttributeError: 'functools.partial' object has no attribute '__module__'
{{{
File "/home/gstarck/work/public/python/django-
all/django/django/urls/base.py", line 91, in reverse
return force_text(iri_to_uri(resolver._reverse_with_prefix(view,
prefix, *args, **kwargs)))
File "/home/gstarck/work/public/python/django-
all/django/django/urls/resolvers.py", line 323, in _reverse_with_prefix
self._populate()
File "/home/gstarck/work/public/python/django-
all/django/django/urls/resolvers.py", line 183, in _populate
self._callback_strs.add(pattern.lookup_str)
File "/home/gstarck/work/public/python/django-
all/django/django/utils/functional.py", line 35, in __get__
res = instance.__dict__[self.name] = self.func(instance)
File "/home/gstarck/work/public/python/django-
all/django/django/urls/resolvers.py", line 141, in lookup_str
return callback.__module__ + "." + callback.__class__.__name__
AttributeError: 'functools.partial' object has no attribute '__module__'
}}}
I have a patch / test case for this..
