The Django problem with "set.all" returns nothing in the template

Question

Hi Stackoverflow people, You will help with the following.

My urls:

path('Autorow/szczegoły/<int:id>/', views.Szczegoly_autorzy, name='Szczegoly_autorzy'),

My views:

def Szczegoly_autorzy(request, id):
   autor = get_object_or_404(Author, pk=id)
   return render(request, 'Szczegoly_autorzy.html', {'autor': autor})

My models:

class Author(models.Model):
   zdjecie_autora = models.ImageField(null=False, blank=True, upload_to='zdjecia_autorow')
   imie_nazwisko = models.CharField(max_length=100, unique=True)
   data_urodzenia = models.DateField(null=True, blank=True)
   informacje = models.TextField()


def __str__(self):
    return self.imie_nazwisko



class Book(models.Model):
    tytul = models.CharField(max_length=60, unique=True)
    autor = models.ForeignKey(Author, on_delete=models.CASCADE)
    opis = models.TextField(null=True, blank=True)
    rok_wydania = models.DateField(null=True, blank=True)
    zdjecie = models.ImageField(null=False, blank=True, upload_to='zdjecia_ksiazek')



def __str__(self):
    return self.tytul

Templates:

        {% for ksiazki in autor.ksiazki_set.all %}
                    <li><a href="{%  url 'Szczegoly_ksiazki' ksiazki.id %}">"{{ ksiazki }}"</a></li>
        {% endfor %}

I don't see the list of books the author wrote in my templates. This is my second app and it works in the first one, but I don't know where I'm making a mistake here. Help me

Consider using English language in your code as field/variable names. Naming your fields/variables in Polish is not good practice. — token, Jan 31 '20 at 07:09

You should use autor.book_set.all instead of autor.ksiazki_set.all

For more info, go through this SO post, What is related_name used for in Django?
