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

Links to Views

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.

Links to Views

The DTL allows us to create links to Views directly. What is meant by this? The URL addresses to Views can be changed while the development process. DTL finds the using URL automatically through the URL pattern name.

Look at the implemented URL pattern inside the urls.py file:

The DTL has tools that insert links from the URL pattern through the pattern name into the HTML page. Such operations are performed using the following syntax:

For example, the link to the post list:

Note

The quotes inside the url function and the href parameter should be different.

Result

Now we have this link in the main page in the browser:

The HTML document structure in browser:

The link opens the http://127.0.0.1:8000/posts/ URL address in your browser.

Thus, you can create links to any endpoint of your application, and changing the URL address will not affect the pages, which protects you from additional changes in the HTML pages.

Everything was clear?

Thanks for your feedback!
