我有兩個文件夾下的'服務'文件夾。他們正在單獨調用該服務。現在我想擴展一個模型，包括相關的模型，這給了一個錯誤'信息：TypeError：無法讀取屬性未定義的'模型'feathersjs/sequelizejs - > MODEL沒有關聯模型
數據庫存在，sql服務器，以及關係也存在。

問題
我認爲我有一個配置錯誤的地方。我使用了一個我自己的工作示例應用程序，其中服務沒有子文件夾，並且關係採用相同的方式。這是行得通的。任何想法的問題是什麼？
解決
好。所以我將activity和activity_Plan移回到服務的根目錄，而不改變除文件位置之外的任何內容。同樣的錯誤。我改變了服務的路徑（刪除了'/ mic'），現在我得到的'activity_plan'與'activity'沒有關聯。
好吧，現在我恢復了我的測試，並有這條線model: hook.app.service('/mic/activity_plan').Model。然後我想到了一些事情。我有自定義主鍵，所以我需要做一些在hasMany，belongsTo部分調查
因此，現在我做了第二個數據庫，通過sequelize（表）strangly，完全相同的問題。
如果我看這條線at Model.validateIncludedElement (D:\Workspace\Projects\01. Live Customers\Mexon Technology\Projects - Mexon\MexonInControl\MultiFunctionalPortal\backend\node_modules\sequelize\lib\model.js:558:11)，然後在它指向的代碼中，這可能是我的模型命名與我的代碼中的行model: hook.app.service('/mfp/sys_metadata').Model組合在一起的問題。
