续集targetKey似乎不与belongsToMany一起生效

Question

belongsToMany和targetKey选项是否存在任何已知问题？

我的模型定义如下：

'use strict';
module.exports = (sequelize, DataTypes) => {
  const Keyword = sequelize.define('Keyword', {
    name: DataTypes.STRING
  }, {});
  Keyword.associate = function(models) {
    Keyword.belongsToMany(models.Location, {
      through: models.SearchRequest
    })

    Keyword.belongsToMany( models.Ranking, {
      targetKey: 'searchRequestId',
      otherKey: {
        name: 'id'
      },
      through: {
        model: models.SearchRequest,
      }
    })
  }
  return Keyword;
};

运行以下命令后：

kwrr > keyword = await Keyword.findOne()()
kwrr > await keyword.getRankings()

生成的sql如下：

Executing (default): 
SELECT 
`Ranking`.`id`, `Ranking`.`googlePageRank`, `Ranking`.`googleResultRank`, 
`Ranking`.`searchRequestId`, `Ranking`.`createdAt`, `Ranking`.`updatedAt`, 
`SearchRequest`.`locationId` AS `SearchRequest.locationId`, `SearchRequest`.`keywordId` AS 
`SearchRequest.keywordId`, `SearchRequest`.`websiteId` AS `SearchRequest.websiteId`, 
`SearchRequest`.`createdAt` AS `SearchRequest.createdAt`, `SearchRequest`.`updatedAt` AS 
`SearchRequest.updatedAt`, `SearchRequest`.`KeywordId` AS `SearchRequest.KeywordId`, 
`SearchRequest`.`LocationId` AS `SearchRequest.LocationId`
FROM `Rankings` AS `Ranking` 
  INNER JOIN `SearchRequests` AS `SearchRequest` 
    ON `Ranking`.`id` = `SearchRequest`.`id` AND 
   `SearchRequest`.`KeywordId` = 101;

我期望的是Rank.id，而不是Rank.id。 INNER JOIN SearchRequests AS SearchRequest ON Ranking.searchRequestId = SearchRequest.id。

根据to the source，它的targetKey应该启用它。

知道为什么它没有生效吗？

p.s我一直遵循源代码，并且targetKey的值已按预期传递，但是生成的sql似乎不兑现它。

谢谢！
