How can i fix Page not found 404 in django? - django

Question

Hi ive been coding my first website and then try running the product page I get this error
*Page not found (404)
Request Method: GET
Request URL: http://127.0.0.1:8000/products
Using the URLconf defined in myshop.urls, Django tried these URL patterns, in this order:
admin/
The current path, products, didn't match any of these.
You're seeing this error because you have DEBUG = True in your Django settings file. Change that to False, and Django will display a standard 404 page.*
how can I solve this? Here is my code...
my views page code
from django.http import HttpResponse
from django.shortcuts import render
def index(request):
return HttpResponse('Hello world')
def new(request):
return HttpResponse('New Products')
productsurls code
from django.urls import path
from . import views
urlpatterns = [
path('', views.index),
path('new', views.new)
]
myshopurls
from django.contrib import admin
from django.urls import path, include
urlpatterns = {
path('admin/', admin.site.urls),
path('products/', include('products.urls'))
}

Answer 1

Most probably, you are facing this problem because you have not include your app "products" in the "settings.py" file.
-> After checking your code I can conclude that"myshop" is your project and "products" is your app.
So, you will have to go in settings.py file under which you will find a list "INSTALLED_APPS".
Inside INSTALLED_APPS -> You will have to include your app.
Go to "apps.py" file of the "products" app and copy the name of the "config" class.
After that in your settings.py file, you will have to write 'products.apps.(paste the name of config class)'.
Most probably name of your config class will be "ProductsConfig" -> So, you will have to write 'products.apps.ProductsConfig',
Hope it will work !

You have to include the app under INSTALLED_APPS in settings.py file.
So your settings.py file should read like so
INSTALLED_APPS = [
# Built In Apps
'django.contrib.admin',
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.messages',
'django.contrib.staticfiles',
# User Defined Apps
'product.apps.ProductConfig',
]
Tip - If you are confused as to how to include the name under installed Apps. It should be like so
<myapp>.apps.<name_of_class_in_myapp/apps.py_file>
Basically navigate to your app folder -> apps.py file and check the name of the class. It will be like so
from django.apps import AppConfig
class ProductConfig(AppConfig):
default_auto_field = 'django.db.models.BigAutoField'
name = 'product'
You want the name of this class. ProductConfig.
Note - Local apps should always be added at the bottom because Django executes the
INSTALLED_APPS setting from top to bottom. We want the core Django apps to be available before our app.
The reason for listing the app like
'product.apps.ProductConfig',
is because it is best practice and helps if in future if you decide to use Django Signals.
