[Dbix-class] Best possible way to retrieve data using relationship

[linuxsupport]

Hi,

I am trying to find best way to fetch data from multiple table using
DBIx::Class relationship.

I have 3 tables as follows.

Articles ( id, title, sort_text) primary key =3D> id
ArticleAuthor (article_id, author_id) primary key =3D> (article_id, author_=
id)
Author (id, author_name) primary key =3D> id

Relationship.

Article.pm
has_many(article_author =3D> "Article::Author", "article_id")

ArticleAuthor.pm
has_many(author =3D> "Author", "id")

I want to get title and sort_text from articles table and author_name form
author table for a given id.
I tried this
$schema->resultset('Article)->search(
{
   id =3D> '1'
},
{ join =3D> { article_author =3D> author }
  prefetch =3D> { article_author =3D> author }
}
);

This returns me all the table filelds from all three table, I tried to put
something columns =3D> [qw/ title sort_text author_name/] but did not work.

I want to know if above is correct way to use relationship? or is there a
better way of doing the same?
And how I can get only required columns.

Thanks
