私は、実生活のイベントを登録して表示するロギングアプリケーションを構築しています。 すべてのデータは、角度2で動作するフロントエンドアプリケーションに入力され、このAPIを使用して情報を取得します。MissingSchemaError：モデル "User"にスキーマが登録されていません。 Mongoose populate issue
私の/ api/eventルートにアクセスしようとするたびに、次のエラーが表示されます。
C:\Users\<UserName>\sites\daily-report\backend\node_modules\mongoose\lib\connection.js:778
throw new MongooseError.MissingSchemaError(name);
^
MissingSchemaError: Schema hasn't been registered for model "User".
Use mongoose.model(name, schema)

誰かが私の問題で私を指摘できますか？私はこの問題を盲目的に見つめ始めている。
マイフォルダ構造は以下の通りである：このファイル内のルートを訪問するとき

多くの感謝！
スキーマを定義したばかりです。あなたのスキーマをどこでモデルにコンパイルしていますか？ –
