Introduction to django with Creating a Simple helloworld App

2 minute read

In this post, we will install Django and will create our first app.

Prepare Environment

Create Directory

First, let’s create a different directory for our django project.

$ mkdir django_tut
$ cd django_tut/

Create and Activate Virtual Environment

Now, let’s create a virtual environment using Miniconda/Anaconda. You can also use pipenv

If you do not know, how to install Miniconda/Anaconda, visit this post first:

Data Science Work Environment setup on Linux/Mac

$ conda create --name django python=3.6
$ source activate django

Install Django

Now, let’s install django using pip

$ pip install django==2.1

Create First Project

Create Project

A project may have several apps running within it.

We will create our first project named first_project in the current directory.

$ django-admin startproject first_project .

Run Server

Now, run the following command to launch our server.

$ python runserver

Let’s open in the browser. If we have the following page, django has been succesfully installed.

Create First App

Create App

Let’s create our first app named hello.

$ python startapp hello

Connect app with project

We have created our first app. However, the django Project does not know about it yet.

So, to connect the app with the project, let’s open the file under first_project directory and add hello under INSTALLED_APPS. Check the last line, we have added hello in the list.

# Application definition

Create a view

Now, let’s create a view for the target URL. To do that, we will open the file under hello directory which looks like as follows:

from django.shortcuts import render
# Create your views here.

Now, let’s add the following lines:

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

# Create your views here.
# View is created as functions
def createView(request):
	return HttpResponse('Hello World')

Here, we have created a view named createView and used HttpResponse to print Hello World on the screen.

Now, let’s restart the server.

$ python runserver

Now, let’s open in the browser. However, we see, it doesn’t work (page not found).

This means, we will have to create a URL for our app.

Create URL

So, we will have to create and link the url in file under first_project directory again.

If we open the file. it will look like as follows:

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

urlpatterns = [

Now, let’s create a custom URL for our app.

from django.contrib import admin
from django.urls import path
from hello.views import createView

urlpatterns = [
path('hello/', createView),

Now, reload the browser page and it will work just fine.
