Am trying to develop an app for student management. Every thing seems to be working fine. but am receiving an errors at some point. If i open the list view it shows all the student, if i click a student photo it will open a detail view of that student for me, then if i click add button inside the view it will show me (NoReverseMatch at /add_subj/3/
Reverse for 'detail' with arguments '('',)' not found. 1 pattern(s) tried: ['(?P[0-9]+)/$'] ). I want to be able to add subject to a particular id. Please need some help, am new in django.
