What does Django’s @property do?

Django’s @property is a Python decorator that allows you to define a method as a property, which means that you can access it like an attribute, without calling it a method. The @property decorator is used to create getter methods in a class.

If you want to know about it properly then just check out this example. It will help you to understand what does @property actually do.

Let’s consider a model class named Employee with three fields: first_name, last_name and full_name (the concatenation of first_name and last_name fields).

class Employee(models.Model):
    first_name = models.CharField(max_length=50)
    last_name = models.CharField(max_length=50)

    @property
    def full_name(self):
        return f"{self.first_name} {self.last_name}"

In the above example, the full_name method is decorated with the @property decorator, which allows it to be called an attribute.

You can now access the full_name property on an instance of the Employee model as shown below:

employee = Employee.objects.get(id=1)
print(employee.full_name)  # Output: John Doe

Here, we are calling the full_name property of the employee object directly as if it were an attribute. The full_name property method is automatically called behind the scenes and the result is returned.

The @property decorator provides a way to encapsulate class properties and make the code more readable and expressive. It can also be used to perform additional operations before returning the value of the property.
