Hi all, I need help. I keep getting this issue, NoReverseMatch at / Reverse for 'productsgrouping-update' with arguments '('',)' not found. 1 pattern(s) tried: ['update/(?P<url_id>[0-9]+)/$']
not sure what am doing wrong. Any time I put url tag {% url 'productsgrouping-update' lista.id%} in html i get the error. Both url work as stand alone,* /index* and */index/update/1/* but when i put url tag all hell break loose.. I strugling for a week now.
