What is the purpose of the Django ORM?

Vaibhav Kothia May 26, 2023 0 Comments

The Django ORM (Object-Relational Mapper) is a powerful tool that enables developers to interact with databases using Python instead of SQL. It helps developers to create, retrieve, update, and delete records from the database with minimal effort.

For example, if you wanted to get a list of all the users in your database, you could use the Django ORM to do this:

users = User.objects.all()

This would return a list of all the users in your database. The Django ORM makes it easy to query the database and get the data you need with minimal effort.

How do you structure a Flask application?

A Flask application is typically structured as follows:

1. Create the application instance:

app = Flask(__name__)

2. Configure the application:

app.config[‘SECRET_KEY’] = ‘your_secret_key_here’

3. Define routes:

@app.route(‘/’)
def index():
return ‘Hello World!’

4. Create the database:

from flask_sqlalchemy import SQLAlchemy

db = SQLAlchemy(app)

5. Create models:

class User(db.Model):
id = db.Column(db.Integer, primary_key=True)
username = db.Column(db.String(80), unique=True, nullable=False)
email = db.Column(db.String(120), unique=True, nullable=False)

6. Create views:

@app.route(‘/users’)
def show_users():
users = User.query.all()
return render_template(‘users.html’, users=users)

7. Create templates:

Users

{% for user in users %}

{{ user.username }} – {{ user.email }}

{% endfor %}

8. Run the application:

if __name__ == ‘__main__’:
app.run()

What is Flask?

Flask is a web framework written in Python. It is a microframework that provides basic features for creating web applications. It is designed to make getting started quick and easy, with the ability to scale up to complex applications.

For example, a basic Flask application might look something like this:

from flask import Flask

app = Flask(__name__)

@app.route(‘/’)
def hello():
return ‘Hello, World!’

if __name__ == ‘__main__’:
app.run()
