Goal:
127.0.0.1:8000/about
Should give:
welcome to to about us page
127.0.0.1:8000/contact
Should give:
welcome to contact page
Problem:
Both are giving "page not found at /"
This error:
This is my folder structure:
This is my main project "taskmate"'s urls.py:
from django.contrib import admin
from django.urls import path, include
urlpatterns = [
path('admin/', admin.site.urls),
path('task/',include('todolist_app.urls')),
path('todolist/',include('todolist_app.urls')),
]
And for todolist_app, these are my details:
Urls.py:
from django.urls import path
from todolist_app import views
#from . import views
urlpatterns = [
path('', views.todolist),
path('contact', views.contact,name='contact'),
path('about', views.about, name="about"), #the path can be anything.
]
Views.py:
from django.shortcuts import render
from django.http import HttpResponse
# Create your views here.
def todolist(request):
context={'welcome_text':"welcome to todo list app"}
return render(request, 'html/todolist.html',context)
def contact(request):
context={'welcome_text':"welcome to contact page"}
return render(request, 'html/contact.html',context)
def about(request):
context={'welcome_text':"welcome to to about us page"}
return render(request, 'html/about.html',context)
I'm suspecting that the problem is in my main project urls.py as I've not included any details about contact and about URLs there. So, I did this there.
from django.contrib import admin
from django.urls import path, include
urlpatterns = [
path('admin/', admin.site.urls),
path('task/',include('todolist_app.urls')),
path('todolist/',include('todolist_app.urls')),
path('about/',include('todolist_app.urls')),
]
The website runs but the goal isn't achieved. Which is obvious because about/ is getting mapped to same URL like todolist/
It shows what the URLs
http://127.0.0.1:8000/task/
And
http://127.0.0.1:8000/todolist/
were Showing instead of what it should be showing.
Now, I think I need to fix the todolist_app urls.py
from django.urls import path
from todolist_app import views
#from . import views
urlpatterns = [
path('', views.todolist),
path('contact', views.contact,name='contact'),
path('about', views.about, name="about"), #the path can be anything.
]
I'm not sure how to fix that. The first thing that I don't understand there is
path('', views.todolist),
should mean any urls 127.0.0.1:8000/ should be giving "welcome to todolist app", but only 127.0.0.1:8000/todolist gives it.
And the views mapping for "contact" and "about" are clearly not working.
How do I fix this issue?
CodePudding user response：
So to achieve your goal, we have to change the project url file as:
path('admin/', admin.site.urls),
path('task/',include('todolist_app.urls')),
path('',include('todolist_app.urls')), # change as this
Then you can get
127.0.0.1:8000/about showing "welcome to about page"
127.0.0.1:8000/contact showing "welcome to contact page"
127.0.0.1:8000/ showing "welcome to todolist app page"
The problem here was in project url file when you add path('todolist/',include('todolist_app.urls')), every urls in the todolist app will be prefixed with the given string in project url file.
You can refer Django - URL Mapping for more.
CodePudding user response：
Add a slash after your route:
from django.urls import path
from todolist_app import views
urlpatterns = [
path('', views.todolist),
path('contact/', views.contact,name='contact'),
path('about/', views.about, name='about'), #the path can be anything.
]
