URL not matching url pattern in Django - django

Question

I'm trying to learn Django, went through the official tutorial and giving it a try on my own. I've created a new app and can access the index page but I can't use pattern matching to go to any other page. Here is my monthlyreport/url.py
from django.urls import path
from . import views
#app_name = 'monthlyreport'
urlpatterns = [
path('', views.index, name='index'),
path('<int:question_id>/', views.detail, name='detail'),
]
and my monthlyreport/views
from django.shortcuts import render
from django.http import HttpResponse
from django.template import loader
from django.contrib.auth.mixins import LoginRequiredMixin
from django.views import generic
from .models import Report
def index(request):
report_list = Report.objects.all()[:5]
template = loader.get_template('monthlyreport/index.html')
context = {
'report_list': report_list,
}
return HttpResponse(template.render(context, request))
def detail(request, question_id):
return HttpResponse("You're looking at question %s." % question_id)
The debug for http://127.0.0.1:8000/monthlyreport/0 is showing
Using the URLconf defined in maxhelp.urls, Django tried these URL patterns, in this order:
monthlyreport [name='index']
monthlyreport <int:question_id>/ [name='detail']
polls/
admin/
accounts/
The current path, monthlyreport/0, didn’t match any of these.
Again, using http://127.0.0.1:8000/monthlyreport/ to go to index works fine, but I cant match the integer. I would really appreciate any suggestions, I am very, very confused at this point.

Answer 1

Problem with your code is of one slash(/). In your root urls.py file, from where you must have used something like:
path('monthlyreport', include('monthlyreport.url'))
So, the problem here is that you should have ending / in your path if you are setting your urls in monthlyreport.url like:
urlpatterns = [
path('', views.index, name='index'),
path('<int:question_id>/', views.detail, name='detail'),
]
Or else, you have to put slash(/) infront of every new path like:
urlpatterns = [
path('', views.index, name='index'),
path('/<int:question_id>/', views.detail, name='detail'),

Solution
In summary, convinient solution is adding slash(/) after path in urls.py file. Like:
path('monthlyreport/', include('monthlyreport.url'))
