Django reverse

Hi,
Can someone please explain what reverse means here?
What are we reversing?
Thanks,

class Author(models.Model):
    """Model representing an author."""
    first_name = models.CharField(max_length=100)
    last_name = models.CharField(max_length=100)
    date_of_birth = models.DateField(null=True, blank=True)
    date_of_death = models.DateField('Died', null=True, blank=True)

    class Meta:
        ordering = ['last_name', 'first_name']

    def get_absolute_url(self):
        """Returns the url to access a particular author instance."""
--->    return reverse('author-detail', args=[str(self.id)])

    def __str__(self):
        """String for representing the Model object."""
        return f'{self.last_name}, {self.first_name}'

Hello @Rafael_Green

i tried to search the js api but did not find function with same signature

so not sure if it api related to django or custom function in the code

but unfortunately could not help and have a nice day

first, thanks for your attempt to help.
second, it’s python, not js
and the reverse is django related function

you welcome
oh my bad sorry i thought it js

i found this
https://www.django-rest-framework.org/api-guide/versioning/#reversing-urls-for-versioned-apis

not sure if it the same function you talking about here or not

and have a nice day
