using with django rest framework

Could you explain how to use django-hashids with DRF correctly when trying to make post request consider this model and serialize files below

model.py

class  Author(models.Model):
	hashid = HashidsField()
	name = models.CharField(max_length=255)
	
class  Book(models.Model):
	hashid = HashidsField()
	name = models.CharField(max_length=255)
	author= models.ForeignKey(Author, on_delete=models.CASCADE)

serilizers.py

class  AuthorSerlizer(serializers.ModelSerializer):
	id = serializers.CharField(source="hashid", read_only=True)
	class  Meta:
		model = Author
		fields = "__all__"
		
class  BookSerlizer(serializers.ModelSerializer):
	id = serializers.CharField(source="hashid", read_only=True)
	author= serializers.PrimaryKeyRelatedField(
	pk_field=serializers.CharField(source="hashid"),
	queryset=Author.objects.all(),
	)
	class  Meta:
		model = Book
		fields = "__all__"



payload = {
"author":  "4JaYJV",
"name":  "book1"
}

this payload raises

"author":  ["Incorrect type. Expected pk value, received str."]}

Thanks in advance

I was able to get this working using DRF's SlugRelatedField

I added this to my model:

hashid = HashidsField(real_field_name="id")

And this to my viewset:

lookup_field = "hashid"

Finally, I changed my PrimaryKeyRelatedField on my Serializer to a SlugRelatedField:

post = SlugRelatedField(slug_field="hashid") # Whatever else you have
