Chapter 2 provides some best practices for Django projects
Best practices aim to optimize the results of production or management practices and reduce the likelihood of error. Some practical methods described in this chapter will be used in the future, which can be regarded as the foundation of project knowledge. Each section will be illustrated with examples.
Chapter 3 Project demand analysis, functional design and technology selection This chapter will analyze what functions need to be realized from the user’s point of view, learn demand analysis, Markdown write project demand documents, close to the principle of “high cohesion, low coupling”, modular design of website functions. The technology selection of the front and back end, and the version of each software.

This chapter introduces Django’s advanced knowledge, such as many-to-many foreign keys in ORM, while implementing the requirements. First use the general class view ListView/DeleteView development function, and then explain the framework of the source code, and then is the Python language in the MRO algorithm, according to the business → framework → source code →Python bottom algorithm order from shallow to deep explanation.
This chapter begins with two of the most common functional requirements in q&A services: slug for detail pages and tag management. According to DRY principle in software development, customize QuerySet in the model class, imitate the mainstream question and answer class website, realize the article Markdown edit and real-time preview effect, implement the function after analyzing CreateView/UpdateView source code.
Chapter 8 GenericRelation relational model class and RequestFactory class test view implementation q&A function: This chapter focuses on the core features of the product, and the business logic is quite complex. First, we’ll take a look at the user-question-answer-uplike/favorit-adopt relationship, and then introduce Django’s contentTypes. GenericForeignKey and GenericRelation are used to solve the problem. In our test cases, we’ll use a more enterprise-friendly approach — the RequestFactory class directly tests the view.
Chapter 9 [Private message] Message query set design, sending and receiving processing private message function includes private message record, online reply, private message prompt, the difficulty lies in the real-time push of the back-end message, this chapter first explains the design of message model class and query set to realize the user to send messages and receive messages processing, and then the principle of WebSocket. Django Channels, consumer Channels, routing, and WebSocket authentication in Django applications.
This chapter is the key and difficult point of the project, and will focus on it. The content includes the analysis of the business scenario of the notification function, the design and implementation of the notification processor, the further practice of WebSocket programming, what is the ASGI server, And how the ASGI request channel service (Redis) inherits the AsyncWebSocketConsumer class to make users connect, disconnect, and receive notifications asynchronously.
In this chapter, you will learn how to use Django-haystack + ElasticSearch to search for articles, updates, questions, users, and tags. You can install and configure Elasticsearch, generate indexes in real time through haystack, and sort search results.
In this chapter, you will learn how to optimize Django projects, including functionality, caching, SQL, etc. Then you will learn how to deploy Python applications, the various WSGI/ASGI protocols, and the use of Nginx reverse proxies.
