"Reverse for 'page' with no arguments not found. 1 pattern(s) tried" in Django-CodePudding

I started testing and studying Django recently and I'm building some projects to learn and test it. I tried looking for answers in the documentation but was unable to find any, if you can send me the documentation reference to solve this with your solution/tip, I'd appreciate it.

I'm trying to pass an argument through the URL in Django, the url changes and the int appears on the browser when redirecting (i.e. http://127.0.0.1:8000/edit-contact/1 - 1 being put dinamically from the "redirecting") but, apparently, the view function can't recognize it.

button I'm using to redirect and send the argument

<a href="{% url 'edit-contact' contato.id%}" >
  Edit contact
</a>

urls.py file:

urlpatterns = [
    path('', views.index, name='index'),
    path('busca/', views.search, name='busca'),
    path('<int:contato_id>', views.details, name='detalhes'),
    path('edit-contact/<int:contato_id>',
         views.edit_contact, name='edit-contact'),

]

view function I'm using to capture the request

@login_required(redirect_field_name='login')
def edit_contact(request, contato_id):
    if request.method != 'POST':
        form = ContatoForm()

        return render(request, 'contatos/detalhes.html', {'form': form, 'contato_id': contato_id})

Traceback:

CodePudding user response：

Does it put a "/" after the 1? On your browser url I.e 127.1.1.8000/edit-contact/1/
