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. Thank you
all in advance.
