Django URLs (Django 2.0+)

August 10, 2018

Note: Skip this tutorial and mark it as “complete” if you’re using Django 1.11 and go to the next tutorial.

This is only meant for students who are learning Django 2.0 and above, as Django changed how it handles url’s in versions 2.0 and above.

We’re about to build our first webpage: a homepage for your blog! But first, let’s learn a little bit about Django URLs.

What is a URL?

A URL is simply a web address. You can see a URL every time you visit a website – it is visible in your browser’s address bar. (Yes! is a URL! And is also a URL.)

Every page on the Internet needs its own URL. This way your application knows what it should show to a user who opens that URL. In Django, we use something called URLconf(URL configuration). URLconf is a set of patterns that Django will try to match the requested URL to find the correct view.

How do URLs work in Django?

Let’s open up the mysite/ file in your code editor of choice and see what it looks like:

"""mysite URL Configuration
from django.urls import path, include
from django.contrib import admin
urlpatterns = [

As you can see, Django has already put something here for us.

Lines between triple quotes (''' or """) are called docstrings – you can write them at the top of a file, class or method to describe what it does. They won’t be run by Python.

The admin URL, which you visited in the previous chapter, is already here:



This line means that for every URL that starts with admin/, Django will find a corresponding view. In this case, we’re including a lot of admin URLs so it isn’t all packed into this small file – it’s more readable and cleaner.

Your first Django URL!

Time to create our first URL! We want ’’ to be the home page of our blog and to display a list of posts.

We also want to keep the mysite/ file clean, so we will import URLs from our blog application to the main mysite/ file.

Go ahead, add a line that will import blog.urls. Note that we are using the include function here so you will need to add that import.

Your mysite/ file should now look like this:

from django.urls import path, include
from django.contrib import admin
urlpatterns = [
    path('', include('blog.urls')),

Django will now redirect everything that comes into to blog.urls and looks for further instructions there.


Create a new empty file named in the blog directory. All right! Add these first two lines:

from django.urls import path
from . import views

Here we’re importing Django’s function path and all of our views from the blog application. (We don’t have any yet, but we will get to that in a minute!)

After that, we can add our first URL pattern:

urlpatterns = [
    path('', views.post_list, name='post_list'),

As you can see, we’re now assigning a view called post_list to the root URL. This URL pattern will match an empty string and the Django URL resolver will ignore the domain name (i.e., that prefixes the full url path. This pattern will tell Django that views.post_list is the right place to go if someone enters your website at the ’’ address.

The last part, name='post_list', is the name of the URL that will be used to identify the view. This can be the same as the name of the view but it can also be something completely different. We will be using the named URLs later in the project, so it is important to name each URL in the app. We should also try to keep the names of URLs unique and easy to remember.

If you try to visit now, then you’ll find some sort of ‘web page not available’ message. This is because the server (remember typing runserver?) is no longer running. Take a look at your server console window to find out why.

Your console is showing an error, but don’t worry – it’s actually pretty useful: It’s telling you that there is no attribute ‘post_list’. That’s the name of the view that Django is trying to find and use, but we haven’t created it yet. At this stage, your/admin/will also not work. No worries – we will get there.
