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 ?

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.

lire.html

...

<h1 style="padding-top : 40px">{{ req.name }}</h1>

<p class="infos">Soumis par moi le {{ req.fromd|date:"DATE_FORMAT" }}</p>

  <p><strong>ID :</strong> {{ req.id }}</p>

  <p><strong>Type de test :</strong> {{ req.typeOfTest }}</p>
