Comment (by rednaw):
Regardless of the use case, your issue should be able to be solved like
this:
{{{
from django.core.urlresolvers import reverse
from django.http.response import HttpResponseRedirect
from django.utils.functional import SimpleLazyObject
def my_view(request):
SimpleLazyObject(lambda:
HttpResponseRedirect(reverse('core:frontpage')))
}}}
But unfortunately this doesn't work at the moment because `LazyObject`
(which `SimpleLazyObject` implements) doesn't implement `__iter__`. This
is required because the `BaseHandler` of `wsgiref` loops through response
objects, which invokes `__iter__`, but if since `LazyObject` doesn't
implement `__iter__` it falls back to `__getitem__` which won't work.
I opened an issue for this:
https://code.djangoproject.com/ticket/23838
I'll make a pull request for the `__iter__` method, when that will be
merged, the code snipped above will work.
