Question

我发现当我使用Sequelize＆＃39; Id＆＃39;正在添加到我的列名称的末尾，但我不确定如何指示Sequelize不这样做？

我为Sequelize创建了一个实体数据模型，如下所示：

function initializeDataModel(sequelize) {
    var dataModel = { };    

    dataModel.Playlist = this.sequelize.define('playlist', {
        name: Sequelize.STRING,
    }); 

    dataModel.PlaylistEntry = this.sequelize.define('playlist_entry', {
        playlist: {
            name: 'playlist',
            type: Sequelize.INTEGER,
            references: {
                // This is a reference to another model
                model: dataModel.Playlist,

                // This is the column name of the referenced model
                key: 'id'

                // This declares when to check the foreign key constraint. PostgreSQL only.
                //deferrable: Sequelize.Deferrable.INITIALLY_IMMEDIATE 
            }               
        },
        track: Sequelize.INTEGER
    });                

    dataModel.PlaylistEntry.belongsTo(
         dataModel.Playlist,
         { as: 'Playlist', foreignKey: { name: 'playlist' }});

    dataModel.Playlist.hasMany(dataModel.PlaylistEntry);

    return dataModel;
}

播放列表中的字段＆＃39; table（在MariaDB中）如下：

id：INT（11）
播放列表：INT（11）
track：INT（11）

我正在执行的查询如下：

    eagerIncludes.push(this.dataModel.PlaylistEntry);

    this.dataModel.Playlist.find({
       where: { id: playlistId },
       limit: limit,
       offset: offset,
       include: eagerIncludes                 
    }).then(function (results) {
        callback(results, options, undefined);
    }).catch(function (error) {
        callback(undefined, options, error);
    });

这导致：

ER_BAD_FIELD_ERROR: Unknown column 'playlist_entries.playlistId' in 'field list'

任何建议将不胜感激。不能选择更改数据库中的列名。

注意，尝试使用＆＃39; eager includes＆＃39;时会遇到这个问题。

基于一些实验，修复是将'foreignKey'属性添加到hasMany定义：

entities.Playlist.hasMany(entities.PlaylistEntry, { foreignKey: 'playlist' });

如何防止Sequelize添加＆＃39; Id＆＃39;到列名？
