this should not be a new file but rather an update for models just want to highlight the category model update

models.py

class Category(models.Model):
    name = models.CharField(max_length=100, unique=True)
    description = models.TextField(max_length=255, blank=True)

    def __str__(self):
        return self.name
    
    class Meta:
        verbose_name_plural = "Categories"
