Replace:
url(r'^$', turk_post, name='post', {'SSL':True}),
with:
url(r'^$', turk_post, name='post', kwargs={'SSL':True}),
The Django url
is a function defined like this:
def url(regex, view, kwargs=None, name=None, prefix=''):
# et cetera
(hence your error as the function expects a keyword argument)
