Colleagues, good afternoon!
There is a model book and a model chapter. Each book has many chapters. Each chapter is tied to a specific book, and if the slug of the chapter is made unique, then when book1 - chapter1, I cannot create book2 - chapter 2, an error is generated. If you make the slug non-unique, then an error is issued that one argument was expected, but 2 was passed.
How can I solve this problem? I want the slug to be a number and django understands that along the path / book1 / 1 / you need to take a slug with number 1, which is tied to book1 specifically, and not to pay attention to the slug with number 1, but tied to book2.
if the slug is unique, then I calmly end up in the right book and the right chapter, but everything collapses when I need to get there as intended.
The path is built like this: / book1 / 1 (chapter) / etc.
book2 / 1 / etc
class Book(models.Model):

class Chapter(models.Model):
book= models.ForeignKey(Book, verbose_name="title", on_delete=models.CASCADE)
number = models.PositiveIntegerField(verbose_name="num chapter")
slug = models.SlugField(unique=True, verbose_name="slug_to", null=True, blank=True)
def save(self, *args, **kwargs):
self.slug = self.number
super().save(*args, **kwargs)
