Django for Everybody (DJ4E)

We look at why Django is a popular web technology and compare it to other web development technologies like PHP.

This walks through the installation steps for Django on PythonAnywhere.

During this class you will be using the command line interface (shell) to work with Linux on PythonAnywhere. Since Linux is the operating system used by most of the cloud servers in production, it is good for you to have a basic understanding of the Linux command line interface. In this section we do a quick overview of using the Shell on PythonAnywhere. For this module you watch a video and take a quiz.

This is a quick look at databases in general and the basic operations (CRUD) in Structured Query Language (SQL). We don't go too far into SQL because we will be using Django's model capabilities to build the databases for our application.

We do a quick look at how Python supports the Object-Oriented programming pattern.

This section explores how we define models in Django and then we build the data models and explore the administration interface for our application.

We briefly cover the basics of the HyperText Markup Language (HTML) that is the markup for web pages. The recorded lectures are from Web Applications for Everybody.

We briefly cover the basics of cascading Style Sheets (CSS) that allow us to style the markup for web pages.

We cover the concept of the Model-View-Controller (MVC) in web applications.

We finally get to looking at the core of a Django application - the views and templates.

We cover how GET and POST work, how forms are constructed from HTML, how we protect our applications against Cross-Site Scripting Forgery (CSRF), and how we handle browser refreshes after POST.

We look at the generic views capability within Django.

In this lesson you will be presented a specification for a simple application. There is no new material - but you might want to review material to help with this assignment.

Now that we have covered most of the components of a Django web application through the Django tutorials, it is a good time to review the structure of a Django application and also look at some of the low level details on how web browsers work with web servers.

In this module, we install and run a very small implementation of the 'Django' web server. It is only a few hundred lines of code and demonstrates the techniques used in the Django application.

We explore how cookies work in the browser and how to set and read cookies in Django. We then explore how cookies are used to support sessions in Django and how we use sessions in Django.

We explore the design of one-to-many data models.

This exercise explores the interaction between authentication and our application.

We cover how to use the Django built in forms objects and their connection to Django models to futher simplify our view processing.

In this assignment we build a small CRUD application from scratch to support an autos database that we will use as a base to build on going forward. This will serve as a way to review some of the concepts in the tutorial that we might have covered a little too quickly.

This module will build a second CRUD application to make sure you know how to make new applications according to a specification. It is a great time to review important concepts in the course in the context of your first complete application.

In this lesson you will be presented with a sample application and you are to replicate its fuctionality. There is no new material - but you might want to review material to help with this assignment.

We start the Django 5.2 Marketplace application by checking out a copy of a GitHub repository and getting it running on PythonAnywhere.

We cover how we mark objects as 'owned' by Django users.

We explore crispy forms and bootstrap menus and then use owned rows we write the first iteration of the marketplace application.

We take a quick look at the JavaScript language.

We do a quick look at how the JavaScript language supports the Object-Oriented pattern.

We add pictures to our classified ads application.

We further explore the design of many-to-many data models and write a Django script to load comma-separated (CSV) data into many-to-many tables.

We add comments to our marketplace application.

We look at particular aspects of the JavaScript run-time in a browser including manipulation of the Document Object Model(DOM) and event handling.

In this section we look at JavaScript Object Notation (JSON). JSON is commonly used as a syntax to exchange data between code running on the server (i.e. in Django) and code running in the browser in JavaScript.

We add favorites to our marketplace application.

We add search a feature our marketplace application.

This is a set of assignments centered around the Mozilla Developer Network Django tutorial.

A set of assignments based on the Django Girls tutorial. Build a blog step by step on PythonAnywhere.
