perhaps delete the comment then 🙂

Ah yes, on line 5! Sorry, I will fix it ASAP. Thank you!

I was thinking about:
changeset = Ecto.Changeset.put_change(post, :permalinks,
perhaps should be
changeset = Ecto.Changeset.put_change(changeset, :permalinks,

As according to Ecto.Changeset docs:

put_change(changeset, key, value)

Specs:

put_change(t, atom, term) :: t

As the documentation for Repo.insert! says, it receives a model (post) or a changeset and it always returns the model (post) in case of success. It raises on failures.

# Let’s track the new permalinks
changeset = Ecto.Changeset.put_change(post, :permalinks,
[%Permalink{url: “example.com/thebest”},
%Permalink{url: “another.com/mostaccessed”}]
)

# Now let’s insert the post with permalinks at once!
post = Repo.insert!(changeset)

Should the post on line 5 be changeset?
