我在＆＃39;服务＆＃39;下面有两个文件夹。夹。他们正在单独调用该服务。现在我想扩展一个模型以包含相关模型，这是一个错误＆＃39;信息：TypeError：无法读取属性＆＃39;模型＆＃39;未定义＆＃39;
数据库存在，sql server，关系也存在。

问题
我认为某处我的配置错误。我使用了一个自己的工作示例应用程序，其中服务没有子文件夹，并且关系以相同的方式进行。那很有效。知道问题在哪里吗？
解决
好。因此，我将activity和activity_Plan移回服务的根目录，而不更改除文件位置之外的任何内容。同样的错误。我改变了服务的路径（删除＆＃39; / mic＆＃39;），现在我得到了活动_计划＆＃39;与＆＃39;活动无关。
好的，现在我恢复了我的测试并且拥有这一行model: hook.app.service('/mic/activity_plan').Model。然后我想到了什么。我有自定义主键，所以我需要在hasMany，belongsTo部分中查看
所以现在我制作了第二个数据库，它是通过sequelize（表格）制作的，完全相同的问题。
如果我查看此行at Model.validateIncludedElement (D:\Workspace\Projects\01. Live Customers\Mexon Technology\Projects - Mexon\MexonInControl\MultiFunctionalPortal\backend\node_modules\sequelize\lib\model.js:558:11)，然后在它指向的代码中，那么在我的代码中将模型命名为行model: hook.app.service('/mfp/sys_metadata').Model可能会出现问题。< / p>
答案 0 :(得分：0)
Object.keys(sequelize.models).forEach(function(modelName) {
if ("associate" in sequelize.models[modelName]) {
sequelize.models[modelName].associate();
}
});
sequelize.sync(
{
force: false
}
);
