Combine 2 CharFields to form an attribute

I want combine the first_name and last_name fields to create a full_name field. Which will then be used to create the slug.

I get NameError: name 'self' is not defined with this code.

class Employee(models.Model):
    first_name = models.CharField(max_length=50)
    last_name = models.CharField(max_length=50, null=True, blank=True)
    full_name = self.first_name + " " + self.last_name 
    slug = AutoSlugField(null=True, default=None, unique=True, populate_from='full_name')

you can create a property in the class. This returns slug property as 

>>> e.slug
'sandesh-daundkar'

class Employee(models.Model):
    first_name = models.CharField(max_length=50)
    last_name = models.CharField(max_length=50, null=True, blank=True)
    slug = AutoSlugField(null=True, default=None, unique=True, populate_from='full_name')

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