i found out maybe because my url did not declare correctly, i mean the
format for example the following works:
urlpatterns = patterns("",
url("^techspec/(?P<slug>.*)", views.tsmodeldetail, name="tsmodeldetail"
),
)
as long as "techspec/(?P<slug>.*)" without "/", it will work.
But then, why this happen, can't understand what cause this problem.
