【实例简介】Django 3 Web Development Cookbook - Fourth Edition (Aidas Bendoraitis)
Django 3 Web Development Cookbook, Fourth Edition, will guide you
through every stage of the web development process with the Django 3.0
framework. We start with the configuration and structuring of the project.
Then, you will learn how to define the database structure with reusable
components, and how to manage it throughout the lifetime of your project.
The book will move on to the forms and views used to enter and list the
data. We'll proceed with responsive templates and JavaScript to augment
the user experience. Then we will enhance Django's template system with
custom filters and tags to be more flexible for frontend development. After
this, you will tailor the administration interface in order to simplify the
workflow of content editors. From there, we shift focus to the stability and
robustness of your project, helping to secure and optimize your apps. Next,
we examine how to efficiently store and manipulate hierarchical structures.
Then we will demonstrate that collecting data from different sources and
providing your own data to others in a range of formats is simpler than you
might think. We will then introduce you to some tricks for programming
and debugging your Django project code. We will move on with a few of
the available options for testing your code. Just before the end of the book,
