Question

我在应该关联的两个表上运行一个简单的查询，但是我不断收到以下消息：

item_translation与项目无关！

基本上item_translation应该属于item。根据{{3}}，我已正确完成了所有操作。这是模型：

ItemTranslation模型：

module.exports = function () {
  return function (app) {
    /** @type {Sequelize.Sequelize} */
    const sequelize = app.get('sequelize')

    const ItemTranslation = sequelize.define('item_translation', {
      _id: {
        type: Sequelize.INTEGER,
        allowNull: false,
        primaryKey: true,
        autoIncrement: true
      },
      sourceId: {
        type: Sequelize.STRING,
        allowNull: false,
        references: {
          model: 'item',
          key: '_id'
        },
        onDelete: 'cascade',
        onUpdate: 'cascade'
      },
      text: {
        type: Sequelize.STRING,
        allowNull: false
      }
    }, {
      freezeTableName: true
    })

    ItemTranslation.associate = function () {
      ItemTranslation.belongsTo(sequelize.models.item)
    }
  }
}

项目模型：

module.exports = function () {
  return function (app) {
    /** @type {Sequelize.Sequelize} */
    const sequelize = app.get('sequelize')

    sequelize.define('item', {
      _id: {
        type: Sequelize.INTEGER,
        allowNull: false,
        primaryKey: true,
        autoIncrement: true
      },
      text: {
        type: Sequelize.TEXT,
        allowNull: true
      }
    }, {
      freezeTableName: true
    })
  }
}

我错过了什么吗？

Answer 1

我不确定，但是尝试一下。我总是明确定义外键。像这样的东西。

ItemTranslation.belongsTo(sequelize.models.item,{foreignKey:'sourceId'})



Item.associate = function () {
      Item.hasMany(sequelize.models.ItemTranslation,{foreignKey:'sourceId'})
    }

“ item_translation与项目无关！”续差
