在依赖类型'Bd.Domain.Entities.FootballGame'上找不到导航属性'FootballGame'

Question

我正在创建我的第一个asp.net mvc3应用程序。我使用的是代码优先方法。我有以下型号：

public class FootballGame 
{ 
    [Key] 
    public Guid id_FootballGame { get; set; } 

    [ForeignKey("FootballGame")] 
    public Guid? FK_id_FootballGame { get; set; } 
    public virtual FootballGame PreviousFootballGame { get; set; } 

    [ForeignKey("FootballTeam")] 
    public Guid id_FootballTeam_owner { get; set; } 
    public virtual FootballTeam FootballTeamOwner { get; set; } 

    [ForeignKey("FootballTeam")] 
    public Guid id_FootballTeam_guest { get; set; } 
    public virtual FootballTeam FootballTeamGuest { get; set; } 
} 

public class FootballTeam 
{ 
    [Key] 
    public Guid id_FootballTeam { get; set; } 
    public string teamName { get; set; } 
} 

而且我有下面的类：

public class EFDbContext : DbContext 
{ 
    public EFDbContext() : base("name=EFDbContext") { } 

    public DbSet<FootballTeam> FootballTeams { get; set; } 
    public DbSet<FootballGame> FootballGames { get; set; } 
} 

不幸的是，有一个例外：

的ForeignKeyAttribute财产 'FK_id_FootballGame' 上 类型'Bd.Domain.FootballGame'无效。在依赖类型 'Bd.Domain.FootballGame'上未找到导航 属性'FootballGame'。名称值应该是有效的 导航属性名称。

我试图删除这些行：

[ForeignKey("FootballGame")] 
public virtual FootballGame PreviousFootballGame { get; set; } 

然而，另一个例外出现：

的ForeignKeyAttribute财产 'id_FootballTeam_owner' 在类型 'Bd.FootballGame' 不是有效。在依赖类型'Bd.FootballGame'上未找到导航属性“FootballTeam” 。名称值 应该是有效的导航属性名称。

我期待着任何帮助。 问候，丹尼斯。

试试这个：

public class FootballGame 
{ 
    [Key] 
    public Guid id_FootballGame { get; set; } 

    public Guid? FK_id_FootballGame { get; set; } 
    [ForeignKey("FK_id_FootballGame")] 
    public virtual FootballGame PreviousFootballGame { get; set; } 

    public Guid id_FootballTeam_owner { get; set; } 
    [ForeignKey("id_FootballTeam_owner")] 
    public virtual FootballTeam FootballTeamOwner { get; set; } 

    public Guid id_FootballTeam_guest { get; set; } 
    [ForeignKey("id_FootballTeam_guest")] 
    public virtual FootballTeam FootballTeamGuest { get; set; } 
}
