[Dbix-class] Many to many relationship searching

[jakac]

Hello,

I am developing application using Catalyst & Postgres and I have a =

simple many to many
relationship that includes following three tables:

- categories (category_id primary key, category_name, users_id, ......)
- articles (article_id primary key, title, content.......)
- categories_articles_rel (rel_id primary key, category_id, article_id)

My schema includes:
# CATEGORIES
__PACKAGE__->has_many( "categories_articles_rel",  =

"MyDB::CategoriesArticlesRel",  { "foreign.category_id" =3D> =

"self.category_id" }, );

# ARTICLES
__PACKAGE__->has_many( "categories_articles_rel", =

"MyDB::CategoriesArticlesRel", { "foreign.article_id" =3D> =

"self.article_id" }, );

# CATEGORIES_ARTICLES_REL
__PACKAGE__->belongs_to( "category_id", "MyDB::Categories",  { =

category_id =3D> "category_id" },);
__PACKAGE__->belongs_to( "article_id", "MyDB::Articles", { recipients_id =

=3D> "recipients_id" }, );


Now I want to get a list of all articles that are in categories that are =

owned by
certain user and order them by some field... Using the plain SQL I would =

normally write:

select a.* from articles a, categories c, categories_articles_rel rel
where
a.article_id =3D rel.article_id
and
c.category_id =3D rel.category_id
and
c.user_id =3D '$someuser'
order by a.title;

(if I want to order by title)

So now my question is - how to do this using DBIx::Class?

Thank you!
