Are a way of propagating changes made to your Django models (which represent your database schema) into the actual database schema. They are a core part of Django's ORM (Object-Relational Mapping) system and help you manage the database schema in a versioned and structured manner.

Is a high-level, open-source web framework for building web applications using the Python programming language. It follows the model-view-template (MVT) architectural pattern and is designed to facilitate rapid development while promoting clean, pragmatic design.

Python programming language

It is interpreted, build upon object-oriented approach, with dynamic semantics, and yes it s high-level programming language. Actively using for rapid development, scripting and gluing part of existing apps.

I can’t stand Django template language. Do I have to use it?

I think this template engine is the best thing ever, but I know that choosing a template language runs close to religion. There’s nothing about Django that requires using the template language, so if you’re attached to Jinja2, Mako, or whatever it's ok.

How can I see the raw SQL queries Django is running?

Make sure your Django DEBUG setting is set to True. Then import connection from django.db. connection.queries is only available if DEBUG is True. It’s a list of dictionaries in order of query execution. Each dictionary has the sql and time property.

If I make changes to a model, how do I update the database?

Take a look at Django’s support for schema migrations. If you don’t mind clearing data, your project’s manage.py utility has a flush option to reset the database to the state it was in immediately after migrate was executed.

Create and set up simple Django project

Create virtual environment and working directories for Django.

Let’s make a directory.


mkdir Project

Go there


cd Project

Installing a virtual environment


python -m venv .venv

Now, activate virtual environment.


source ./.venv/bin/activate


source ./.venv/Scripts/activate

To check a successful activated virtual environment, execute this command to be sure:


pip list

We will see either 0 or a couple of them. Or we can run a next command on the Linux system.


which python

And if the displayed path to Python is in our working directory, i.e. Project/.venv so everything is working.

How to create Django project

Install a package called Django.


pip install django

Start a new project called Project1


django-admin startproject Project1

Go to Project1


cd Project1

Accept all migrations.


./manage.py migrate

How to start Django project / testing it

Now you can be able to start start testing(local) server.


./manage.py runserver

If everything is done right, you shall see:
