Struct ManyToMany 

pub struct ManyToMany<M: Model>(pub Vec<<M as Model>::Pk>, _);

A many-to-many relation field. The pivot table is auto-generated by rango makemigrations.

Example

#[derive(Model)]
struct Article {
    id: FieldUuid,
    tags: ManyToMany<Tag>,                      // auto pivot table

    #[field(through = "ArticleTag")]
    contributors: ManyToMany<User>,             // explicit pivot table
}

Tuple Fields

0: Vec<<M as Model>::Pk>

Always empty when loaded from the database: use .prefetch_related(Model::FIELD) and .prefetched::<M>() to load the related rows.
