ERROR: (models.E015) 'ordering' refers to the nonexistent field, related field, or lookup 'name'

Question

I simply can't understand why I get this error:

(models.E015) 'ordering' refers to the nonexistent field, related field, or lookup 'name'

from django.db import models

class Category(models.Model):
    name = models.CharField(max_length=255),
    slug = models.SlugField()

    class Meta:
        ordering = ('name',)

    def __str__(self):
        return self.name

    def get_absolute_url(self):
        return f'/{self.slug}'

Answer 1

Ah, I guess it is the comma at the end of the name field declaration...

Answer 2

Remove the comma and have it this way:

class Meta:
    ordering = ('name')

Then run the makemigrations && migrate commands.
