Sequelize属于ToMany验证错误

Question

我从3天起就遇到了问题。我想在 Sequelize 中创建多重关系n：m ，但我收到错误消息：＆＃34; 未处理拒绝SequelizeUniqueConstraint错误：验证错误＆＃34;

所以我有3张桌子：

• 意甲。
• 集。
• 季节（在此表中我想添加与 Serie 和 Episode 的关系）。

以下是Serie的定义：

var Serie = sequelize.define('Serie', {
      idSerie: {
          type: DataTypes.INTEGER,
          primaryKey: true,
          autoIncrement: true
      },
      name: DataTypes.STRING
    }, {
    classMethods: {
      associate: function(models) {
        // associations can be defined here
      }
    }
  });

剧集：

var Episode = sequelize.define('Episode', {
      idEpisode: {
          type: DataTypes.INTEGER,
          primaryKey: true,
          autoIncrement: true
      },
      description: DataTypes.TEXT
    }, {
    classMethods: {
      associate: function(models) {
        // associations can be defined here
      }
    }
  });

和季节：

var Season = sequelize.define('Season', {
        idSeason: {
            type: DataTypes.INTEGER,
            primaryKey: true,
            autoIncrement: true
        },
        numero: DataTypes.INTEGER,
        idEpisode: DataTypes.INTEGER,
        idSerie: DataTypes.INTEGER
    }, {
    classMethods: {
        associate: function(models) {
            // associations can be defined here

            models.Episode.belongsToMany(models.Serie, { through: models.Season, foreignKey: 'idEpisode', otherKey:'idSerie' });
            models.Serie.belongsToMany(models.Episode, { through: models.Season, foreignKey: 'idSerie', otherKey:'idEpisode' });
      }
    }
  });

要添加新关系，我使用了这个：

// serieFound was fetched using findOne and newEpisode was created
serieFound.addEpisode(newEpisode);

PS：我使用 sequelize-cli 创建数据库。

非常感谢任何帮助！
