Customizing models
Model methods are custom functions written within a model class that provide added functionality related to a single record within a table. They let us create our own business logic and format field data as we need to. Django provides us with several default methods and we can also write our own custom methods. Custom methods can combine fields and return data derived from those two or more fields. Decorators are sometimes used in combination with model methods to provide even more functionality.
Some methods can let us perform special operations when an object is saved and/or deleted at the database level. Other methods are used when queries are performed or when rendering an object within a template. We will discuss some of the methods that Django provides and then demonstrate their uses. For a complete breakdown of the full capabilities of using Django's model methods, visit their documentation, found here: https://docs.djangoproject.com/en/4.0/topics...
