Django URLS

URLs in Django are in the format of regular expressions, which are easily readable by human’s. A Regular Expression also called regex is a format for search pattern which is much cleaner and easy to read for the humans and is very logical. We will learn how to import the view functions and connecting different url-conf files with the main urls.py file. First, we will have to import the view function that we want our server to run when the URL is matched. For that, we have to import the function from the views.py file.

urls.py:

from django.contrib import admin

from django.urls import path

#from helloworld.views import Index

from helloworld.views import Hello

urlpatterns = [

path('admin/', admin.site.urls),

path('helloworld/',Hello)

]

​

view.py:

​

#from django.shortcuts import render

from django.http import HttpResponse

​

def Hello(request):

   return HttpResponse("Hello")

​

Different formats of url:

There are many way to write django path here we include some important for Django any projects:

​

• By using path and its method:

       path('helloworld/',Hello)

​

• Using path with name:

       from django.urls import path

       from . import views

       urlpatterns = [

         path('', views.Hello, name='Hello'),

        ]

​

• Using url regular expression: 

        url(r'^$', views.Hello, name='Hello' )
