Javascript 续集：“；模型尚未定义”的；当跨多个数据库建立关系时

我正在尝试实例化每个数据库的一个续集。DB1中的一些表与DB2中的表有关系，反之亦然。其中一个关系是DB1.usilisateur.contenuprogence_id=>DB2.Contenu.id和DB2.Contenu.usilisateur_id=>DB1.usilisateur.id

以下是Usilizateur模型：

@Table
export default class Utilisateur extends Model<Utilisateur> {

    @API() @PrimaryKey @AutoIncrement @Column({ type: DataType.INTEGER })
    public id!: number;

    @Column({ type: DataType.STRING, allowNull: false })
    public email!: string;

    @Column({ type: DataType.STRING, allowNull: false })
    public nom!: string;

    @ForeignKey(() => Utilisateur)
    @Column({ type: DataType.INTEGER, allowNull: true })
    public parrain_id?: number;

    @ForeignKey(() => Contenu)
    @Column({ type: DataType.INTEGER, allowNull: true })
    public contenuProvenance_id?: number;
}

问题：创建第一个实例（DB1）时，sequelize找不到内容表，并给出以下错误：

Sequalize不支持多个迁移文件夹，也不区分您为各个型号设置的方法。您必须非常具体。我无法判断您是否来自您提供的

看看这个问题是否有帮助：
您必须围绕默认路径配置一种方式

这也可能提供一些见解：

你可以在这里阅读Sequalize关于迁移的详细说明：
嗨，我遇到了完全相同的问题，你能解决吗？嗨，因为Sequelize在很多方面都不能满足我的需要，所以我最终编写了自己的orm。
