Hi! can you include the urls.py code? this is mainly because you have not included the <id> within the url setup

I think the problem is in the data into turf_id. Are you sure that turf_id contains only integer value? it's strange the problem with argument: '('',)' - try to verify the data passed with turf_id if are correct...

i used turf_id from django default id column. my doubt is the django default id column isn't integer?

[Migui Galan]

thank you! i think this is because you are not looping or have a turf_id in the template. by 'loop' or have you tried '/add_time_lot/<int:turf_id>/'?

thank you for your replay. i tried  path('/add_time_slot/<int:turf_id>/', views.add_time_slot, name='add_time_slot'),
 but i getting the same error. when i  manually type  this /add_time_slot/1/  in the address bar i  get the page that's what i don't understand

To resolve this issue, you should check the place in your code where
the URL reversal with the name 'add_time_slot' is happening with an
empty argument (''). Ensure that the argument being passed to the URL
reversing function isn’t empty and correctly matches the URL pattern
specified in your URL configuration.
