An In-Depth Comparison – Flask vs Django

According to the 2019 Stack Overflow developer survey, Python has risen in the ranks of programming languages. This popularity is not only due to applications in artificial intelligence or big data. Python can be used to build server-side web applications.

Both Django and Flask are hugely popular as Python Web frameworks. In this article, we’ll compare two widely used Python Web Frameworks.

(Note: I’m a big fan of another Python Web Framework called Masonite, so I’ll keep this comparison as objective as possible though).

Framework Installations

Both frameworks can be installed with the package-management system pip.

Flask installation

Flask installation is as simple as below:

pip install Flask touch app.py

BashCopy

Put the source-code below into app.py:

from flask import Flask app = Flask(__name__) @app.route("/") def hello(): return "Hello World!"

PythonCopy

You can run your app with this command:

FLASK_APP=app.py flask run

That’s it! Your Flask application is available on URL http://localhost:5000/.

Django installation

You need to scaffold a bunch of files to start.

pip install Django django-admin startproject django_project python manage.py runserver

BashCopy

Now that the server’s running, visit http://127.0.0.1:8000/ with your Web browser. You’ll see a “Congratulations!” page.

Project layout

Django provides a conventional project structure with several applications. But you should create your own project’s structure when using Flask.

Framework Configurations

Flask Configurations

The config attribute of the Flask object is as a config object. For example:

# app.py app = Flask(__name__) app.config['TESTING'] = True

PythonCopy

Django Configurations

A Django settings file contains all the configuration of your Django installation. Here are a couple of example settings:

# settings.py TESTING = True

PythonCopy

Routing

Flask Routing

Flask provides a route() decorator to tell Flask what URL should trigger a function:

# app.py @app.route('/') def hello_world(): return 'Hello, World!'

PythonCopy

Django Routing

Django lets you design URLs however you want:

# urls.py from django.urls import path from . import views urlpatterns = [ path('/', views.home), ]

PythonCopy

Templates

Django ships with a template engine called Django Template Languageand Flask ships with Jinja. Both template engines implement two main features: Template inheritance, Blocks or sections, if/else, for-loops.

Object Relational Mapping (ORM)

Django web framework includes a default ORM that can be used to interact with the application database.

User.objects.all()

Flask does not come with ORM capabilities by default. You need to manually add it if you want. Many Flask Developers prefer SQLAlchemy for database access.

User.query.all()

Admin Interface

Django provides a functional admin module automatically based on your project models. The developers even have the option to customize the admin interface to meet specific business requirements.

Community

Several popular websites use Django: Mozilla, Instagram, The Washington Times and so on. Flask is used by Pinterest or LinkedIn.

REST API

With the JavaScript’s frameworks popularity, REST APIs can be used to perform requests and receive responses via HTTP.

REST API in Flask

There are many Flask extensions to help you build RESTful services: Flask-RESTful for example. But you can use what Flask provides itself:

# app.py from flask import Flask, jsonify app = Flask(__name__) todos = [ { 'name': 'Learn Flask' }, { 'name': 'Learn SQLAlchemy' } ] @app.route('/todos', methods=['GET']) def get_todos(): return jsonify({'todos': todos})

PythonCopy

REST API in Django

Django Rest Framework (or simply DRF) is a powerful module for building web APIs using Django. It’s very easy to build model-backed APIs that have authentication policies and are browsable.

Django or Flask?

There’s no clear winner between Django and Flask, as everything depends on your final goal. Flask and Django both have their strengths and weaknesses. Django is very complete, with regard to ORM, admin interface etc. It’s well documented. But Django has a steep learning curve. Flask might be a better choice because you can learn it fast.

What is Django?

Django is a web framework coded in Python. It is open-sourced and was developed for programmers to create applications and websites faster. The framework is maintained by the Django Software Foundation. Django offers flexibility, scalability, and reliability to developers. Learn more about the Django applications.

It is very secure owing to its user authentication system that makes handling user accounts and passwords easy.

Being open-source, you can download the source code easily. It has a powerful community that constantly enhances the framework by adding plug-ins and updates.

How model queries work in Django

How model queries work in Django

Welcome to my blog, hey everyone in this article we are going to be working with queries in Django so for any web app that you build your going to want to write a query so you can retrieve information from your database so in this article I’ll be showing you all the different ways that you can write queries and it should cover about 90% of the cases that you’ll have when you’re writing your code the other 10% depend on your specific use case you may have to get more complicated but for the most part what I cover in this article should be able to help you so let’s start with the model that I have I’ve already created it.

**Read More : **How to make Chatbot in Python.

Read More : Django Admin Full Customization step by step

let’s just get into this diagram that I made so in here:

django queries aboutDescribe each parameter in Django querset

we’re making a simple query for the myModel table so we want to pull out all the information in the database so we have this variable which is gonna hold a return value and we have our myModel models so this is simply the myModel model name so whatever you named your model just make sure you specify that and we’re gonna access the objects attribute once we get that object’s attribute we can simply use the all method and this will return all the information in the database so we’re gonna start with all and then we will go into getting single items filtering that data and go to our command prompt.

Here and we’ll actually start making our queries from here to do this let’s just go ahead and run** Python manage.py shell** and I am in my project file so make sure you’re in there when you start and what this does is it gives us an interactive shell to actually start working with our data so this is a lot like the Python shell but because we did manage.py it allows us to do things a Django way and actually query our database now open up the command prompt and let’s go ahead and start making our first queries.
