If Ecto.build_assoc(post, :comments, body: "Excellent!")
is equivalent to %Comment{post_id: post.id, body: "Excellent!"}
, why do we have build_assoc
in Ecto? I found it sometimes confusing to use.

Those are equivalent, yes. The goal of build_assoc is to allow you to work on the association names instead of the key names. That’s it.
