How do I manage database relationships in Django APIs?

In Django, you can manage database relationships using ForeignKey, OneToOneField, and ManyToManyField. Would you like to know more about a specific type?

Can you explain ForeignKey and how to use it?

Sure! A ForeignKey is a field that creates a many-to-one relationship. You define it in your model like this: author = models.ForeignKey(Author, on_delete=models.CASCADE).

What does on_delete=models.CASCADE do?

The on_delete=models.CASCADE option means that when the referenced object is deleted, all related objects will also be deleted.

Are there any best practices for using these relationships?

Yes, it's best to use related_name for reverse relationships, and always consider the implications of cascading deletes.
