How to get value in class view?

Question

Django

There is such a design, class-based view, how can I get the value of a specific property of my own object?
For example, the value of the property name or last_accessed? Tried get_context_data methods but didn't figure out
models.py

class Author(models.Model):
    salutation = models.CharField(max_length=10)
    name = models.CharField(max_length=200)
    email = models.EmailField()
    last_accessed = models.DateTimeField()

views.py

class AuthorDetail(DetailView):
    model = Author
    template_name = 'author_detail.html'

Where to get? In the template, in the logic of the view? If inside a view, then in any method, including the notorious get_context_data(), you can access the object by calling the get_object() method:

def get_context_data(self, **kwargs):
    author = self.get_object()
    kwargs.update(last_accessed=author.last_accessed,
                  name=author.name)
    return super().get_context_data(**kwargs)

If we are talking about a template, then by default a variable with an object is called unpretentiously - object. Respectively. in the text of the template, you can write

Hi, {{ object.name }}, you're seen at {{ object.last_accessed }}

If you don't like the object name, you can specify the name of this variable through the context_object_name attribute of your CBV:

class AuthorDetail(DetailView):
    context_object_name = 'author'
    model = Author
    template_name = 'author_detail.html'

and it will be possible to write in the template:

Hi, {{ author.name }}, you're seen at {{ author.last_accessed }}
