I've been stuck here for two days.
The error came out of nowhere.
One sec ago, it was all ok. Then, the error jumped out.
I am not a programmer. Coding is just a hobby. I have no one I can consult with.
So please please please, save me.
LATEST UPDATES
The project is working now. It is totally creepy and strange. Below is what I did:
In #app/aftersales/url.py
path('', views.aft,name='aft'),
path('aft/edit/<int:id>',views.aft_edit,name='aft_edit'),
path('view/<int:id>',views.aft_view,name='aft_view'),
]
I added 'aft/' in the second path(). Totally out of desperation.
obviously, it's wrong. And error popped.
I deleted the 'aft/'.
Then everything goes back to normal.
I have no idea what happened.
Thanks to everyone who gave me advice! Deeply!

Answer 1

Without seeing your views I can't be sure, but the issue is likely in your template due to the way arguments are being passed into your template tag.
<td>
</td>
Remove the key / equals sign and simply pass the argument value. Assuming the context you're passing the template includes itm this should render the links correctly and the reverse match error will go away.
Before: id=itm.id
After: itm.id
Note that I tested this on one of my own templates by adding the arguments as key value pairs like in your example and got the same error.
