私たちのアプリ。複雑なセキュリティルールセットを持っています。Entity Framework表示するマッピングを追加
私はSQL文でルールを実装し、それをLinqとSQLとEntity Frameworkに変換しました。 EFはデータセット上で行わなければならないフォローアップクエリの性質上、いくつかのパフォーマンス上の問題を抱えていましたので、私は文章を最大限制御できるSQLでフィルタリングを行うだけでよいと思いましたパフォーマンスを保証するために実行されます。私はそれをビューに収めました.EFで基底として使用することを考えていたのですが、&は残りのフィルタリングを続けていますが、既存のテーブルをビューにマッピングする際に問題があります。
あなたはスクリーンショットで見ることができるよう、すべての3つの列は、エンティティのキーとして識別されています。問題は、ビューのFKを定義できないため、EFは接続の作成方法を知らないということです。私が手作業でそれらを作成しようとすると、EFは3つの列すべてへの接続を指定する必要があると不平を言っています。私はもう一方の端からもそれを試しましたが、サイコロはありませんでした。ここで
は.edmxです：ちょうど右のプロパティをクリックし、フィールドIDをクリックして、「エンティティキー」設定のプロパティウィンドウでvwEntitiesFilterで<?xml version="1.0" encoding="utf-8"?>
