Django error browser is unable to connect at 127.0.0.1:8000/products/

问题

I am creating my first Django project. I have successfully installed Django version 2.1. When I created the project, the project was successfully launched at the url 127.0.0.1:8000. Then I ran the command python manage.py startapp products. Products folder was also successfully created in the project. Then inside the products folder, I opened: views.py

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


def index(request):
    return HttpResponse('Hello World')

then products/urls:

from django.urls import path
from . import views

urlpatterns = [
    path('', views.index)
]

Inside the main project folder, I opened urls.py and I modified the code:

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

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

Then the url http://127.0.0.1:8000/products/ was not opening on browser. Browser is giving the "Unable to connect" error. I am using the PyCharm IDE. I will really appreciate your answer.

回答1:

In you settings.py add the app to the INSTALLED_APPS list as:

 INSTALLED_APPS =
 [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'products' # <-- your product app 
]

And modify ALLOWED_HOSTS list as:

ALLOWED_HOSTS = ['localhost', '127.0.0.1']

Then run the application:

python manage.py runserver 127.0.0.1:8080.

回答2:

Check if you had ran the command below:

python manage.py runserver

If you had run the above command and the error persists, try to run on the global address 0.0.0.0

python manage.py runserver 0.0.0.0:8000

OR on a different port

python manage.py runserver 0.0.0.0:8001
