This blog will discuss Django's fundamentals and applications. It will also explain why Django is a good choice for currency API integration. Additionally, the blog includes a step-by-step guide for integrating the CurrencyFreaks Currency Conversion API.
What is Django?
Django is a free and open-source web application framework. It is written in Python and follows an MVC architecture pattern.
Django focuses on simplicity and speed in app building. It adheres to the DRY (Don't Repeat Yourself) principle. This keeps the code neater and developers more efficient.
The framework has built-in modules for common tasks. These include user authentication, database integration, URL management, and security features. Django also mitigates general-purpose threats like XSS and CSRF.
It enhances security and speeds up web development. Its scalability and strong community support make it appealing for developers.
Real-Life Applications Using Django

Django's flexibility and built-in security make it ideal. It supports high-end web-based application development with ease and accommodates features such as product management feature requests and a priority roadmap input, enhancing its adaptability for diverse use cases.
Why Should You Choose Django for currency API Integration?
Django is excellent for currency exchange API integration. It simplifies API requests through pre-installed modules, making it suitable for managing historical rates and monthly requests efficiently. This ensures fast retrieval and processing of currency data without hidden fees.
Its ORM (Object Relational Mapper) integrates seamlessly with various databases. This improves storage and data management, supporting tasks such as international sales for e-commerce stores and international brands.
Django prioritizes application security. It protects against threats like XSS, CSRF, and SQL injection. Users remain safe during transactions, even with a high requests volume.
Caching solutions enhance data-loading speed. Frequently changing views load without delays, which is critical for annual billing and quarterly briefing calls in business environments.
Django's modular structure allows easy modifications. Applications can be updated as needed for business requirements, offering platinum support click solutions for enhanced customer satisfaction.
The framework suits projects of any size. It handles real-time currency exchange rate applications effectively, including features like historical rates and high-volume monthly requests.

How Do You Integrate CurrencyFreaks currency API with Django?
1. Set Up the Django Project
Step 1.1: Install Django
Install Django using pip:
pip install django
Step 1.2: Create a Django Project
Create a new Django project named currency_exchange:
django-admin startproject currency_exchange
cd currency_exchange
Step 1.3: Create a Django App
Create an app named exchange within your project:
python manage.py startapp exchange
2. Configure the Django Project
Step 2.1: Register the App
In currency_exchange/settings.py, add the exchange app to INSTALLED_APPS:
INSTALLED_APPS = [
...,
'exchange',
]
Step 2.2: Set Up URLs
Project URLs (currency_exchange/urls.py)
Update your urls.py file to include the app URLs and a homepage route:
from django.contrib import admin
from django.urls import path, include
from django.views.generic import TemplateView
urlpatterns = [
path('admin/', admin.site.urls),
path('api/', include('exchange.urls')), # API routes
path('', TemplateView.as_view(template_name='exchange/index.html'), name='home'), # Homepage
]
App URLs (exchange/urls.py)
Create a new urls.py file in the exchange app directory and add API routes for fetching currency data.
from django.urls import path
from . import views
urlpatterns = [
path('supported-currencies/', views.get_supported_currencies, name='supported_currencies'),
path('convert/', views.convert_currency, name='convert_currency'),
]
3. Backend Logic for APIs
Step 3.1: Add Views
In exchange/views.py, add the following views to handle API requests:
from django.http import JsonResponse
import requests
def get_supported_currencies(request):
api_key = 'your_currencyfreaks_api_key' # Replace with your API key
url = 'https://api.currencyfreaks.com/v2.0/supported-currencies'
response = requests.get(url)
if response.status_code == 200:
return JsonResponse(response.json())
return JsonResponse({'error': 'Failed to fetch supported currencies'}, status=500)
def convert_currency(request):
api_key = 'your_currencyfreaks_api_key' # Replace with your API key
from_currency = request.GET.get('from', 'USD')
to_currency = request.GET.get('to', 'EUR')
amount = float(request.GET.get('amount', 1))
url = f'https://api.currencyfreaks.com/v2.0/rates/latest?apikey={api_key}&base={from_currency}&symbols={to_currency}'
response = requests.get(url)
if response.status_code == 200:
data = response.json()
if to_currency in data.get('rates', {}):
rate = float(data['rates'][to_currency])
converted_amount = round(rate * amount, 2)
return JsonResponse({'from': from_currency, 'to': to_currency, 'rate': rate, 'converted_amount': converted_amount})
return JsonResponse({'error': 'Failed to fetch conversion rate'}, status=500)
4. Frontend (Single File)
Step 4.1: Create the HTML File
Place the HTML, CSS, and JavaScript code in a single file named index.html within the exchange/templates/exchange/ directory.
File: exchange/templates/exchange/index.html
<!DOCTYPE html>
