链接 urls&views 后，“hello world”在 django 中不可见

Question

i have just now started learning the django basics,but i have been keeping on facing a problem with the urls & views. i do not get the "Hello world" after i reload or even try adding myapp name in the url

wrote this code for the project url

from django.contrib import admin
from django.urls import include, path

urlpatterns = [
    path('', include('calc.urls')),
    path('admin/', admin.site.urls),
]

wrote this for myapp urls

from django.urls import path
from . import views

urlpatterns = [
    path('', views.home, name='home'),
]

wrote this for the views

from django.shortcuts import render
from django.http import HttpResponse

# Create your views here.
def home(request):
    return HttpResponse("Hello world");

what is the mistake i am doing?

link: http://127.0.0.1:8000/calc

Answer 1

You are not setting the correct URL. Also have you added your in installed apps? if yes then visit: http://127.0.0.1:8000

or add calc in your url to use http://127.0.0.1:8000/calc

urlpatterns = [
    path('calc', views.home, name='home'),
]

Answer 2

Is your myapp urls file inside a folder called calc? If it isn't then try doing something like this:

Change include('calc.urls') to include('\the folder name in which myapp urls is in\.urls')

Then use the http://127.0.0.1:8000 and it should work.
