Django vs Flask choosing the best python framework

In this article, Django vs. Flask – Choosing the Best Python Framework, we will describe the significant aspect of these frameworks and choose the best framework that’s perfect for you. So let’s discuss these frameworks.

Introduction to Django

Django is a high-level Python framework that encourages the perfection of your project’s design.

It’s free and open source web application framework developed by professional developers.

Django is fast, secure, exceedingly scalable, and incredibly versatile.

Django was explicitly created for simplifying the creation of complex projects. It facilitates low coupling, less coding, and the natural use of the make-up component.

Pros of Django

  • The Django framework has an MVC architecture comprising of an object-relational mapper (ORM) that moves data models and a relational database, a system processing HTTP requests, and a regular-expression-based URL dispatcher.
  • It’s a light weighted framework with a standalone server for the development and testing of applications.
  • It has a caching framework that uses any cache methods.
  • Django supports four database backend like PostgreSQL, Oracle, MySQL, and SQLite.
  • Django has a growing community of developers, with conferences held every year in different countries.
  • It’s been used in some well-known sites like Instagram, Udemy, Spotify, and more.

Introduction to Flask

Flask is a web framework written in Python. It has good syntax that’s easy to understand.

Its built-in technology is easy to understand; this makes it easy for beginners to get started with.

Flask focuses on users request and the responses to deliver back to its user.

It doesn’t require a particular tool or libraries; no database abstraction layer except third party libraries which are imported to provide common functions.

Pros of Flask

  • Flask contains a development server and a debugger.
  • It produces extensive documentation of projects.
  • Flask offers extensions available to enhance features desired. It is Unicode based, with fully integrated support for unit testing.
  • Flask is based on two micro frameworks a utility library for Python programming called Werkzeug, and a template engine called Jinja.
  • It’s used by popular websites such as LinkedIn, Pinterest, and more.

Why use Django?

Django has a fast growing community. It has over eighty thousand questions on stack overflow and also set of quality blogs from several developers.

Encountering a problem while coding wouldn’t be an issue as answers to the most challenging issues are already available on the internet.

We would try to differentiate between Django and Flask in attempting to add data into a database

Using a ModelForm in Django, the data will be automatically inserted into the form. Here we will try to create a structure in which a user creates a post. This post form will take in 2 values, the title of the post and the content of the post.

So the first thing we have to do is create our database. We will call our database, Post. It will only have two fields: title and content.



#models.py File

from django.db import models

class Post(models.Model):

title= models.CharField(max_length=300, unique=True)

content= models.TextField()

This is a primary database. We have a title and a content field. Now we’ll create our template file named createpost.html we are going to have the form where a user can submit a post. This is a simple form that only contains two fields: title and content.


<head>

<title>Create a Post </title>

</head>

 
<body>

<h1>Create a Post </h1>

<form action="" method="POST">

{% csrf_token %}

Title: <input type="text" name="title"/><br/>

Content: <br/>

<textarea cols="35" rows="8" name="content">

</textarea><br/>

<input type="submit" value="Post"/>

</form>

</body>

 
</html>

We need a name attribute with each form field because this is how we will extract the data that the user enters into the area.

Lastly, we have our views.py file. In this file, we will take the data that the user has entered into the form fields and insert the data into a database. The following code in the views.py file does this.



from django.shortcuts import render

from .models import Post

 
 
def createpost(request):

if request.method == 'REVIEW':

if request.REVIEW.get('title') and request.REVIEW.get('content'):

review=Review()

post.title= request.REVIEW.get('title')
post.content= request.REVIEW.get('content')
post.save()
 
return render(request, 'posts/create.html')
 
else:

return render(request,'posts/create.html')

This is how data is inserted into a database from an HTML form in Django.

Using Django will reduce your expenses in developing applications because it doesn’t require massive tool and libraries compared to Flask. Its database system can be applied widely to produce complex projects.

Why use Flask?

Flask has a smaller community compared to Django. It uses a variety of libraries for building a complex project, but its best suited for a smaller project. Flask has a flexible framework. Flask’s Hello World app has to be the simplest out there, having just seven lines of code.



from flask import Flask
app = Flask(__name__)
 

@app.route("/") # take note of this decorator syntax, it's a common pattern

def hello():

return "Hello World!"
 
if __name__ == "__main__":

app.run()

The following code will display “Hello world.”

Most of its functionality is extremely extensible. It’s Modular and has a light weighted design. Its framework provides HTTP request handling. Its API is coherent and easy to deploy during production.

Conclusion

Django makes it easier to build better Web apps more quickly and with less code.  Flask doesn’t need a particular tool or library, and it’s also preferable for smaller projects. Both frameworks are great to use, but only the framework that’s ideal for your project development should be considered.
