问下关于sequelize的关联查询的问题。

我有两个model Blog,Catalog Blog的代码大致是这样 sequelize.define("Blog",{ blogId:{xxx}, catalogId:{xxx}, ... } Catalog的代码大致是这样 sequelize.define("Catalog",{ catalogId:{xxx}, ... } 现在想做关联查询于是我写了他们之间的关系： Blog.belongsTo(Catalog,{foreignKey:'catalogId'}); Catalog.hasMany(Blog,{as:'Catalog'});

然而生成的代码是这样的： SELECT Blog.blogId, Blog.catalogId, ...,Blog.CatalogCatalogId, Catalog.catalogId AS Catalog.catalogId,... FROM blog AS Blog LEFT OUTER JOIN catalog AS Catalog ON Blog.catalogId = Catalog.catalogId;

我就想问下为什么会生成一个加粗部分，我是哪里写得有问题？说实话sequelize的文档真的好难看
