Making a URL shortner app in Django
In this article, we will see how to make a URL shortner app in Django. It is a simple app which will convert a long URL into a short one. We will achieve this using a Python library, not any Django-specific library, so you can use this code in any Python project.
First of all, create a Django project and an app. Do some basic settings like including urls of app and including app in INSTALLED_APPS in settings.py.
Example
Install the pyshorteners module −
pip install pyshorteners
In app's urls.py −
from django.urls import path
from .views import url_shortner
urlpatterns = [
path('', url_shortner.as_view(), name="url-shortner"),
]
Here we set the viewset as view on home url.
Now in views.py −
from django.shortcuts import render
import pyshorteners
from django.views import View
class url_shortner(View):
def post(self, request):
long_url = 'url' in request.POST and request.POST['url']
pys = pyshorteners.Shortener()
short_url = pys.tinyurl.short(long_url)
return render(request,'urlShortner.html', context={'short_url':short_url,'long_url':long_url})
def get(self, request):
return render(request,'urlShortner.html')
Here we created a view with two request handler functions, get handler will render the frontend html and post handler will get the long URL and re-render our frontend with the short URL.
Create a templates folder in app's directory and add urlShortner.html in it and write this −
<!DOCTYPE html>
<html>
<head>
<title>Url Shortner</title>
</head>
<body>
<div >
<h1 >URL Shortner Application</h1>
<form method="POST">{% csrf_token %}
<input type="url" name="url" placeholder="Enter the link here" required>
<button >Shorten URL</button>
</form>
</div>
</div>
{% if short_url %}
<div>
<h3>Your shortened URL /h3>
<div>
<input type="url" id="short_url" value={{short_url}}> <button name="short-url">Copy URL</button> <small id="copied" class="px-5"></small>
</div>
<br>
<span><b>Long URL: </b></span> <a href="{{long_url}}">{{long_url}}</a>
</div>
{%endif%}
</body>
</html>
This is the frontend which will take the long URL and send the request, then it returns the short URL.
