ok.. shame on me.. it works with: $author_tutorial = new AuthorTutorial(); $author_tutorial->author_id = $author->getId(); $author_tutorial->tutorial_id = $tutorial->getId(); $author_tutorial->save();
But how do I check for duplicates - if the $author is already linked with the tutorial? Do I need to do a SELECT manually or is their some function like: $tutorial->hasAuthor($author)?
