Reverse for 'modification' with no arguments not found issue
Hello everyone,
I know I may ask this question for another time for some of you but after
an hour of research, I'm still stuck with this issue of "No Reverse Match".
Here is my problem :
- First, I using forms to put information in my DB (tickets) ;
- I want to be able to edit those informations (check if a ticket has
been handled) ;
- When I'm trying to call again my form to edit my information, even if
I give a specific ID, no way to reach it.

Re: Reverse for 'modification' with no arguments not found issue
Thanks James for your help.
Indeed, I tought about that problem but I already managed to see an number
on an other page, as well as using that ID to read information behind my
informations (as you can see in the third line I gave on "lire.html"). A
number is printed. How can I know that it is an *int* and not a *string*
use in there ?

Re: Reverse for 'modification' with no arguments not found issue
My "home" variable is defined with a view : def home(request): """ Acceuil du site qui recense toutes nos requêtes pour le moment """ return render(request, 'insertion/accueil.html', locals()) Which redirect to my homepage. The line with a problem is that one return render(request, 'insertion/modification.html', locals()) And I really can't figure it out why, according the fact that "locals()" contains my variable and even if I send directly my variable instead, I get the same !
