Description

In https://docs.djangoproject.com/en/2.0/topics/db/examples/many_to_many/ , the text says there are two Publication objects ("a couple" and "both"), but the code example creates three, and uses three.

Create a couple of Publications:

p1 = Publication(title='The Python Journal')
p1.save()
p2 = Publication(title='Science News')
p2.save()
p3 = Publication(title='Science Weekly')
p3.save()

[...]

Create another Article, and set it to appear in both Publications:

a2 = Article(headline='NASA uses Python')
a2.save()
a2.publications.add(p1, p2)
a2.publications.add(p3)
