How to display filters in Django admin?

Question

Django

Hello. I'm learning django - there was a problem in the process of learning. It was necessary to add filters to the admin.py file as in the lesson, but nothing comes out. Already tried from all sides...
admin.py

from django.contrib import admin
from . import models


admin.site.register(models.Example)
admin.site.register(models.Author)
admin.site.register(models.Book)
admin.site.register(models.Place)
admin.site.register(models.Restaurant)
admin.site.register(models.Waiter)
admin.site.register(models.Publication)
admin.site.register(models.Article)




class AuthorAdmin(admin.ModelAdmin):
    list_display = ['name' , 'surname']
    # list_display = [field.name for field in models.Author, meta.fields]  какая то ошибка в этой строке
    # exclude = ['name'] # прячет поле name
    # fields = ['name', 'surname'] # показывает поле
    # list_filter = ['name']
    # search_fields = ['name', 'surname']
    # search_fields = [field.name for field in models.Author, meta.fields]


class Meta:
    model = models.Author


admin.site.register(models.Author, AuthorAdmin)

here is models.py

from django.db import models




class Example(models.Model):
    integer_field           = models.IntegerField()
    positiv_field           = models.PositiveIntegerField()
    positive_small_field    = models.PositiveSmallIntegerField()
    big_integer_field       = models.BigIntegerField()
    float_field             = models.FloatField()
    binary_field            = models.BinaryField()
    boolean_field           = models.BooleanField()
    char_field              = models.CharField(max_length=5)
    text_field              = models.TextField(max_length=20)
    date_field              = models.DateField(auto_now=True)
    date_time_field         = models.DateTimeField(auto_now_add=True)
    decimal_field           = models.DecimalField(max_digits=8, decimal_places=2)
    email                   = models.EmailField()
    file_field              = models.FileField(upload_to='file')
    image_field             = models.ImageField(upload_to='images')


class Author(models.Model):
    name       = models.CharField(max_length=50, verbose_name = 'Имя')
    surname    = models.CharField(max_length=50, verbose_name='Фамилия')
    date_birth = models.DateField(auto_now=False, verbose_name='Дата рождения')

    def __str__(self):
        return 'Имя : %s Фамилия : %s' %(self.name, self.surname)

    class Meta:
        verbose_name = 'Автор'
        verbose_name_plural = 'Авторы'

class Book(models.Model):
    CHOICE_GENRE = (
        ('comedy' , 'Comedy'),
        ('tragedy' , 'Tragedy'),
        ('drama' , 'Drama'),
    )


    author = models.ForeignKey(Author, on_delete=models.CASCADE)
    title  = models.CharField(max_length=50)
    text   = models.TextField(max_length=1000)
    genre  = models.CharField(max_length=50, choices=CHOICE_GENRE)

    def __str__(self):
        return self.title


class Place(models.Model):
    name = models.CharField(max_length=50)
    address = models.CharField(max_length=80)

    def __str__(self):
        return '%s the place' % self.name

class Restaurant(models.Model):
    place = models.OneToOneField(Place, on_delete=models.CASCADE)
    serves_hot_dog = models.BooleanField(default=False)
    serves_pizza = models.BooleanField(default=False)

    def __str__(self):
        return '%s the restaurant' % self.place.name

class Waiter(models.Model):
    restaurant = models.ForeignKey(Restaurant, on_delete=models.CASCADE)
    name = models.CharField(max_length=50)

    def __str__(self):
        return '%s the waiter at %s' % (self.name, self.restaurant)


class Publication(models.Model):
    title = models.CharField(max_length=30)

    def __str__(self):
        return self.title

    class Meta:
        ordering = ('title', )

class Article(models.Model):
    headline = models.CharField(max_length=100)
    publications = models.ManyToManyField(Publication)

    def __str__(self):
        return self.headline

    class Meta:
        ordering = ('headline', )

produces the following picture
Tried to prescribe as in docs 2.2 - ie. in admin.py import Author - but the output always has an error - the final is always the same - it is impossible to register AuthorAdmin.
I've already broken my whole brain - help me out with advice please ...
