How do I set up model relations in Django?

In Django, you can set up model relations using ForeignKey, OneToOneField, and ManyToManyField. Which one are you interested in?

Can you explain ForeignKey in more detail?

Sure! A ForeignKey creates a many-to-one relationship. For example, if you have a Book model and an Author model, each book can be linked to one author, but an author can have multiple books.

How do I implement a ManyToManyField?

To implement a ManyToManyField, you simply define it in your model like this: authors = models.ManyToManyField(Author). This allows each book to have multiple authors and each author to write multiple books.

What are some best practices for using model relations?

Some best practices include using related_name for reverse lookups, keeping your models clean, and using the Django admin to visualize relationships.
