我有一个问题,我有两个模型; “地理封锁”和“国家/地区”,以及关联:

GeoBlockingModel:

Date

协会:

Table2

问题在于,SMALL(above,3)模型具有两个主键,const TYPE_BLACK = 0x10; const TYPE_WHITE = 0x20; export const ETYPE_CONTENT = 0x10; export default (sequelize, DataTypes) => { const GeoBlockingModel = sequelize.define('GeoBlocking', { targetUUID: { type: DataTypes.UUID, primaryKey: true, }, entityType: { type: DataTypes.INTEGER.UNSIGNED, primaryKey: true, validate: { isIn: { args: [[ ETYPE_CONTENT, ]], msg: `Unknow entity type`, }, }, }, type: { type: DataTypes.INTEGER.UNSIGNED, allowNull: false, defaultValue: TYPE_BLACK, validate: { isIn: { args: [[ TYPE_BLACK, TYPE_WHITE, ]], msg: `Unknow type`, }, }, }, } //... GeoBlockingModel.associate = function(models) { CountryModel = models.countries; GeoBlockingModel.belongsToMany(CountryModel, { as: 'countries', through: { model: 'GeoBlockingCountry', timestamps: true, paranoid: false, }, // foreignKey: ['targetUUID', 'entityType'], constraints: true, }); }; 。并且仅通过一个字段关联来创建直通模型:

GeoBlocking

如果我取消注释entityType,该字段将被冠以targetUUID

有什么主意吗?
