Functional overview
In previous chapters, diagrams at the start represented views, templates, and end-to-end functionalities. This chapter, however, shifts the focus to implementing model inheritance and creating custom model fields, topics not easily captured in our usual diagrams. Instead, you will see specific diagrams to illustrate these concepts throughout the chapter.
The source code for this chapter can be found at https://github.com/PacktPublishing/Django-5-by-example/tree/main/Chapter12.
All the Python modules used in this chapter are included in the requirements.txt file in the source code that comes with this chapter.
