That is true, but of course in Django the field is an object, and it is
the object that knows it's name.
There is nothing to stop you declaring a field in a model called
'person_name' but also doing this in the code :
user_name = instance.person_name
In Django the user_name variable will only have the name 'person_name',
but not user_name, as the field objects need to know their names on the
model (and their names on the views/forms).

Subject: [Python-ideas] Re: Extract variable name from itself
A little late, but the requirement to "Extract variable name from
itself" is widely used in Django. Each field in a Django model, knows
it's own variable name
user_name = models.CharField(...)
The instance of CharField knows that it's variable name is "user_name",
so that it can name the row in the database the same.
On startup Django runs through the Model class searching for instances
of Field and gets the name that way
