ロングタイムリーダー、初めてのポスター。Asp MVC 2既存の電子メールアドレスに対するリモート検証ですが、編集についてどうですか？
私はASP MVC 2とリモート検証を使用しています。 AddPersonVMとEditPersonVMが継承するPersonVMというモデルがあります。これは、両方のサブクラス化されたモデルの間で同じUIのほとんどを処理するために1つのusercontrolを使用できるようにするためです。

get {
if (_listOfPersonTypes == null) {
_listOfPersonTypes = Data.PersonTypes
.Where(pt => pt.OrganizationID == ThisOrganization.ID || pt.OrganizationID == null)

私はこのモデル（AddPersonVMとEditPersonVM）を継承した2つのモデルを持っています。それぞれは、変更の仕方を少し違って処理する方法を実装しています。
[UniqueEmailAddress]は私のRemoteAttributeで、既存の電子メールアドレスと問題のあるものを確認します。
誰かを追加してもうまくいきますが、既存の人物を編集すると、既に保存されている電子メールアドレスがメンバーシップシステムに存在するため、検証に失敗します。私がしたいのは、プロパティの値の元の値を保存し、それをIsValidのチェックから除外することです。
マイコード：
/// <summary>
/// Checks to be sure that an entered email address is unique.
/// </summary>
public class UniqueEmailAddressAttribute : RemoteAttribute
{
/// <summary>
/// Returns true if the email address specified is currently in use.
/// </summary>
/// <param name="emailAddress"></param>
/// <returns></returns>
public static bool IsEmailAddressInUse(string emailAddress) {
return (Membership.FindUsersByEmail(emailAddress).Count != 0);
}
///////////////////////////
public UniqueEmailAddressAttribute() : base("UniqueEmailAddress", "RemoteValidation", "emailAddress") { }
///////////////////////////
public override bool IsValid(object value) {
// If value is null, return true, since a [Required] attribute handles required values.
if (value == null)
return true;
// Value must be a string.
if (!(value is string))
return false;
// We're not checking the validity of the email address here,
// the [EmailAddress] attribute handles that for us.
// Check the email's uniqueness.
return !IsEmailAddressInUse((string)value);
}
}
私が持っていると思い何を：
/// /// Checks to be sure that an entered email address is unique. /// public class UniqueEmailAddressAttribute : RemoteAttribute {
string OriginalValue = null;
/// <summary>
/// Returns true if the email address specified is currently in use.
/// </summary>
/// <param name="emailAddress"></param>
/// <returns></returns>
public static bool IsEmailAddressInUse(string emailAddress) {
return (Membership.FindUsersByEmail(emailAddress).Count != 0);
}
///////////////////////////
public UniqueEmailAddressAttribute() : base("UniqueEmailAddress", "RemoteValidation", "emailAddress") {
OriginalValue = value Found using reflection or something;
}
///////////////////////////
public override bool IsValid(object value) {
// If value is null, return true, since a [Required] attribute handles required values.
if (value == null)
return true;
// Value must be a string.
if (!(value is string))
return false;
// We're not checking the validity of the email address here,
// the [EmailAddress] attribute handles that for us.
if ((string)value == OriginalValue)
return true;
// Check the email's uniqueness.
return !IsEmailAddressInUse((string)value);
}
}
任意のアイデア？現時点では、EmailAddressプロパティをAddPersonVMとEditPersonVMの両方に個別に追加し、自分のusercontrolビューからフィールドを取り出して両方のビューに追加し、Editで属性を削除することができましたが、彼らが望む電子メールアドレス。元の値を読み取るために反射が必要な場合は気にしません。

@swapneel最初に投稿したときに、コードから無関係な情報をたくさん整えました。より多くのコードを整えることができると確信していますが、私はインフラストラクチャの観点から何か間違ったことをしている場合、誰かがそれを指摘することを望んでいます。 –
