I am working on an app to host some books online. I cant figure out the
best way to represent a one to many relationship.
Basically, a Book has multiple Chapters, but a Chapter can only be in
one book.
Looking at the docs, this seems to be the way to represent this:
------
class Book(models.Model):
class Chapter(models.Model):
book = models.ForeignKey(Chapter)
------
Is that right? This seems a little counterintuitive to me, and something
like this seems to make more sense:
------
class Book(models.Model):
chapters = models.ManyToManyField(Chapter)
class Chapter(models.Model):
------
Of course, that means that a chapter can be placed on multiple books.
The second example, also seems to make it a little easier to work with
Books, as I can do:
Book.objects.all()
and get the Chapters associated with each book.
So, what is the "correct" way to model this relationship?
Thanks for any input...
