Proxy models offer a valuable mechanism in Django to create “virtual” models that inherit the fields (columns), methods, and behaviors of an existing model without introducing actual changes to the underlying database table.

This can significantly enhance your project’s organization, maintainability, and code readability, especially when dealing with different objects that share a common base or require slight variations.

Important Features and Benefits of Proxy Models

Metaclass Inheritance: Proxy models utilize the __metaclass__ attribute to create a new model class directly from another model. This approach avoids the need for explicit field definitions, keeping your code concise.

Customization: You can customise proxy model by —

• Defining custom managers or querysets through the queryset or objectsattribute to efficiently retrieve relevant data.
