Answer 1

You are using a @dataclass way of defining your model. I'm not aware that will work... It should be:

class Feature(models.Model):
    name = models.CharField(max_length=100)
    details = models.CharField(max_length=200)

Also, have you run migrations? (I suspect not or I think you'd have seen an error here). You should run python manage.py makemigrations followed by python manage.py migrate when you create or amend a model definition - this is what creates/changes it in the DB, and without that there's not a lot to display in admin anyway...

It's possible if you ran migrate it created an "empty" model maybe, since you were missing the = - I really don't know exactly what this code would do without testing it.
