Build a Banking System API with DJANGO Restframework

We're going to take you step-by-step to build a modern, fully open-source,Banking System RESTful API using Python, Django Rest Framework.

This course will teach you exactly how to build one with Django, Python, Django Rest Framework, and more.

Section 1| Django start project

1 - Requirements: no code

Prerequisites required include:

• Python 3
• Pip 3
• Virtualenv
• Django == 3.2.9

Django Installation Instructions

• Make directory in your workspace: mkdir banksystem_project

• Navigate into banksystem_project

  cd banksystem_project

• Create a python virtual environment to install django and other dependecies in the future.

  virtualenv .env

  .env is the directory where we install the packages.

• Activate the virtual environment.

  source .env/bin/activate

• Install Django framework. We are going to use django==3.2.9 in this tutorial.

  pip3 install django==3.2.9

OR

pip install django==3.2.9 If python3 is the default version running.

• Create django project:

  django-admin startproject banksystem

That's it !!!!! You did it 😃 👏 👏

If you want to see the blank project we created follow the link below.

1 - Blank Django Project

Now lets create an application called api inside our project banksystem. To learn more about django applications.

2 - Create api app

Run the following command in your root folder where manage.py lives.

./manage.py startapp api

The app api will be created and your whole project folder structure should look like this.

[banksystem_project]/
├── [banksystem]/
│   ├── __init__.py
│   ├── settings.py
│   ├── urls.py
│   └── wsgi.py
|____[api]/
|    |__ __init__.py
|    |__ models.py
|    |__ views.py
|    |__[migrations]/
|    |  |___ __init__.py
|    |
|    |__admin.py
|    |__tests.py
|
└── manage.py

Include api application in django settings.py

  INSTALLED_APPS = [
  'django.contrib.admin',
  'django.contrib.auth',
  'django.contrib.contenttypes',
  'django.contrib.sessions',
  'django.contrib.messages',
  'django.contrib.staticfiles',
  'api',
]

Learn about django project structure.

Section 2| Django Rest Framework

1 - Introduction: no code

2 - Install Django Rest Framework

Install using pip ...

pip install djangorestframework====3.12.4
pip install Markdown==3.3.6      # Markdown support for the browsable API.
pip install django-filter==21.1  # Filtering support

Add 'rest_framework' to your INSTALLED_APPS setting in settings.py.

INSTALLED_APPS = (
    ...
    'rest_framework',
)

If you're intending to use the browsable API you'll probably also want to add REST framework's login and logout views. Add the following to your rooturls.py file. Location of urls.py banksystem_project/banksystem/urls.py

urlpatterns = [
    ...
    url(r'^api-auth/', include('rest_framework.urls'))
]

Note that the URL path can be whatever you want.
