m2m

[myOmikron]

Would be nice to have m2m relations with this syntax

#[derive(Model)]
pub struct Repo {
    #[rorm(id)]
    pub id: i64,

    #[rorm(m2m, on_update = "Cascade", on_delete = "Cascade")]
    pub owners: Many2Many<m2m!(User::F.repos)>,
}

#[derive(Model)]
pub struct User {
    #[rorm(id)]
    pub id: i64,

    #[rorm(m2m, on_update = "Cascade", on_delete = "Cascade")]
    pub repos: Many2Many<m2m!(Repo::F.owners)>,
}
