1. Get Started

This section provides an introduction to Django and its key concepts. It covers the explanation of Django as a web framework, the MVT architectural pattern it follows, and the steps to initialize a new project using Django. The section also includes instructions on running the server.

What is Django?

Model-View-Template

Challenge: Build the Project

2. Write the First Page

If you are ready to write your first HTML page on Django - now is the time. Here you can learn how to respond to web requests using the Python programming language.

Connect View to URL

Challenge: Write your View

3. Models

Do you think that building a database using Python is not possible? It's not true! Let's start to do it with Django!

How to create a Model?

Challenge: Zoo Market Table

4. Working with Database

If you already know how to build a database, then it's time to manipulate data from it. Django ORM is a tool that allows you to work with data from a database. Let's take a look at it, shall we?

Update and Delete Data

Challenge: CRUD with Person

5. Templates

The HTTP response as a string doesn't look good. It is worth correcting this by using DTL technology, which allows you to dynamically generate beautiful HTML pages and return them to the user.

Template Folder

6. Request Handling

You can learn how to answer requests in the previous sections but how to transfer information and process it? Passing data via HTTP request and retrieving is easy. You just have to figure it out, you can find help here.

Distribution of Request Methods

Request Data Extract

Create Post with Input Data

What is Model?

Model is a class that represents a table from a database. Attributes of a model class are attributes of a table in the database (columns or fields).

Instances of this class are records (data) in the database.

Consider the table below for a better understanding:

Look at the attributes of this table on the ER diagram.

The ER diagram represents the table structure. We can build this structure in the Django project using the Django ORM.

Note

Object Relation Mapping (ORM) is an interface for database manipulation.

The code of this table structure should look like this:

Where:

Product is a table name.
name, price, and quantity are attributes of the Product table.
models is a package with Django ORM tools.

Note

The id field is created automatically in Django. We will describe this later.
