Re: Reverse for 'reg/{{post.pk}}/' with arguments '()' and keyword arguments '{}' not found. 0 pattern(s) tried: []

Have you done the django tutorial ? It help a lot when starting with django.

Your problem come from site1/urls.py . `include(admin.site.urls)` work
because you import admin. `include(site1.reg.urls)` cannot work
because site1 is not defined.

Also, the djangogirls tutorial [1] have a great chapter about form.
