Hibernate many-to-many delete.

Question

Hello,

I have many-to-many relationship in NHibernate between two classes Actor and Movie.

    public ActionResult removeMovieFromActor(int MovieId, int ActorId)
    {
        ViewData["SectionTitle"] = "Usunięcie filmu";
        ActorsRepository ar = new ActorsRepository();

        Actor act = ar.getActor(ActorId);

       //what to do here?

        return RedirectToAction("listMovies");
    }

How can I remove a Movie from act.Movies and make that persistent to the db?

Answer 1

Hard to tell without seeing more of your model and how your mapped your relationships. Assuming you have IList<Movie> Actor.Movies...

Movie movie = mr.GetMove(MovieId);
act.Movies.Remove(movie);
ar.Update(act);
