A web framework is a software library that is designed to support the development of web applications. There are many frameworks that have been developed including Ruby on Rails, Django, Laravel, ASP.NET, Angular, and Express. But in this guide, we will be looking at how to install and use Django KDE Neon / Kubuntu Linux system.
Django is a free, open-source high-level web framework based on Python. It was invented to meet the needs of experienced web developers by eliminating repetitive tasks which make the development process time-saving and easy. It generally reduces the hassle that comes with developing web applications.
Features of Django Framework
- Ridiculously fast in development with less coding
- Loosely coupled to reduce risks of data loss
- Secure and helps developers to avoid security mistakes
- Scalable and flexible to meet even the heaviest demands.
- Clean design making it maintainable.
- Complete and Fully Loaded with extras used to handle common web development tasks
- Versatile in that it can be used to build different web applications
In this guide, I will show you how to
- Install Django on KDE Neon
- Create a Django application
Install Django Framework on KDE Neon / Kubuntu
To Install Django, You are required to set up python and pip in your system.
Setup Python and Pip on KDE Neon / Kubuntu
Update the package index first by running the following command:
sudo apt update
If there are any upgrades required use the command the next command to upgrade the packages.
sudo apt upgrade
By default python is installed in the system, You can test this using
If not then install using
sudo apt install python3
The installation is successful as shown below
To confirm the installation use
$ python3 --version
The version is displayed as follows
pip which is a package manager for python packages
sudo apt install python3-pip
If prompted on disk space to be used, type
Y to continue with the installation.
To check the version use the command:
The version is displayed as follows
Install Django on KDE Neon/Kubuntu from the Repository
Now install Django using the commands shown below:
sudo apt install python3-django
This install from the repository as below
To check the installation was successful, use
It displays the version as below
Creating a Sample Project using Django
First, install Python virtual environment on your Kubuntu / KDE Neon system.
sudo apt install python3-virtualenv
If prompted with disk space type
Y to continue with the installation
Then create a directory for your project using
Then change to that directory using
Next will be to create a new virtual environment.
$ virtualenv newproject created virtual environment CPython3.8.10.final.0-64 in 159ms creator CPython3Posix(dest=/home/ubuntu/django-app/newproject, clear=False, global=False) seeder FromAppData(download=False, pip=latest, setuptools=latest, wheel=latest, pkg_resources=latest, via=copy, app_data_dir=/home/ubuntu/.local/share/virtualenv/seed-app-data/v1.0.1.debian.1) activators BashActivator,CShellActivator,FishActivator,PowerShellActivator,PythonActivator,XonshActivator
Go to the
newproject directory and activate the environment
Then install packages into the isolated environment using
Now install Django using the pip command
$ pip3 install django (newproject) [email protected]:~/django-app/newproject$ pip3 install django Collecting django Downloading Django-4.0.3-py3-none-any.whl (8.0 MB) |████████████████████████████████| 8.0 MB 10.2 MB/s Collecting asgiref<4,>=3.4.1 Downloading asgiref-3.5.0-py3-none-any.whl (22 kB) Collecting backports.zoneinfo; python_version < "3.9" Downloading backports.zoneinfo-0.2.1-cp38-cp38-manylinux1_x86_64.whl (74 kB) |████████████████████████████████| 74 kB 7.4 MB/s Collecting sqlparse>=0.2.2 Downloading sqlparse-0.4.2-py3-none-any.whl (42 kB) |████████████████████████████████| 42 kB 4.3 MB/s Installing collected packages: asgiref, backports.zoneinfo, sqlparse, django Successfully installed asgiref-3.5.0 backports.zoneinfo-0.2.1 django-4.0.3 sqlparse-0.4.2
The output is as follows
Now create a Django project named
technixleo . You can replace the name with however you want to save the file.
django-admin startproject technixleo
Navigate to the new directory using:
You can check the contents of the application by using
Now edit the configuration files inside
On the ‘ALLOWED_HOSTS’ configuration, input your System’s IP address as below.
ALLOWED_HOSTS = ['your-server-ip-address']
If you have more than one Ip address you want to access the Django server just separate them with a comma.
Next, we will migrate the database for our Django project.
Migrate the Django database using the following command.
$ python3 manage.py migrate Operations to perform: Apply all migrations: admin, auth, contenttypes, sessions Running migrations: Applying contenttypes.0001_initial... OK Applying auth.0001_initial... OK Applying admin.0001_initial... OK Applying admin.0002_logentry_remove_auto_add... OK Applying admin.0003_logentry_add_action_flag_choices... OK Applying contenttypes.0002_remove_content_type_name... OK Applying auth.0002_alter_permission_name_max_length... OK Applying auth.0003_alter_user_email_max_length... OK Applying auth.0004_alter_user_username_opts... OK Applying auth.0005_alter_user_last_login_null... OK Applying auth.0006_require_contenttypes_0002... OK Applying auth.0007_alter_validators_add_error_messages... OK Applying auth.0008_alter_user_username_max_length... OK Applying auth.0009_alter_user_last_name_max_length... OK Applying auth.0010_alter_group_name_max_length... OK Applying auth.0011_update_proxy_permissions... OK Applying auth.0012_alter_user_first_name_max_length... OK Applying sessions.0001_initial... OK
By default, the Django framework uses the SQLite database.
After that, create a new admin user for your Django project.
python3 manage.py createsuperuser
Now type your username, email address, and password, then press enter.
Note: use a strong password and not be like me 🙂
Run Django Application
Run the Python Django runserver command below.
python3 manage.py runserver 0.0.0.0:8000
The server starts running as shown below
Open your browser and access the Django application with your server IP and port 8000
You can get your System IP address by using
ip a command.
Add admin to the end of the address to log in to the admin dashboard.
Enter your credentials to log in to the administration dashboard. This allows you to create users and groups.
You have learned how to set up Python and Pip in your system which in turn led to installing Django from the repository. You also learned how to create a Django application in an isolated environment. You also learned how to run the Django application on a web browser which in turn shows the installation is successful.
