MVC實體框架中的一對多關係出錯4

Question

當我運行我的代碼優先的MVC應用程序並嘗試訪問DeveloperAccountModel詳細信息頁面或加載父對象和另一個視圖時出現以下錯誤DeveloperAccountModel集合：導航屬性「重定向」不是類型爲'DeveloperAccountModel'的聲明屬性。在這一點上，我沒有訪問屬性（它確實存在！）只是試圖加載DeveloperAccountModel。

[Table("sitedata")] 
public class DeveloperAccountModel 
{ 
    [Required] 
    [RegularExpression("^[0-9]*$")] 
    [Display(Name = "User id")] 
    [Key] 
    [Column("_rowid")] 
    public long RowId { get; internal set; } 

    // Other properties removed 

    [Display(Name = "Redirects")] 
    [NotMapped] 
    [InverseProperty("DeveloperAccount")] 
    public List<SiteRedirectModel> Redirects { get; internal set; } 
} 

再依賴模型

[Table("siteredirects")] 
public partial class SiteRedirectModel 
{ 
    [Key] 
    [Column("_rowid")] 
    [Display(Name = "RowId")] 
    public int RowId { get; internal set; } 

    [Column("_siteid")] 
    [Display(Name = "Developer account id")] 
    public long DeveloperAccountModelId { get; internal set; } 

    [NotMapped] 
    [ForeignKey("DeveloperAccountModelId")] 
    public virtual DeveloperAccountModel DeveloperAccount { get; internal set; } 
} 

我已經嘗試了各種教程這麼多的變化和樣本，包括其他時間，其中本或類似的錯誤發生，但我沒有看到很簡單的東西。任何人都可以幫忙嗎？

只需從兩個屬性中刪除[NotMapped]屬性。所以你的屬性定義應該是這樣的：

// In SiteRedirectModel 
[ForeignKey("DeveloperAccountModelId")] 
public virtual DeveloperAccountModel DeveloperAccount { get; internal set; } 




// In DeveloperAccountModel 
[Display(Name = "Redirects")] 
[InverseProperty("DeveloperAccount")] 
public List<SiteRedirectModel> Redirects { get; internal set; }
