無效列名稱 - RC2

我收到錯誤「無效列名」的實體框架RC 2，下面是我的實體無效列名稱 - RC2

public class Article : IEntityBase 
    {  
     public Article() 
     { 
      TagMaps = new List<ArticleTagMap>(); 

     } 
     public int Id { get; set; } 

     [Required, MaxLength(100), MinLength(3)] 
     public string Slug { get; set; } 

     [Required] 
     public string Title { get; set; } 

     [Required] 
     public string Description { get; set; } 

     [MaxLength(255)] 
     public string ShortDescription { get; set; } 

     [MaxLength(255)] 
     public string Metadata { get; set; } 

     public virtual ICollection<ArticleTagMap> TagMaps { get; set; } 

    } 

public class Tag :IEntityBase 
    { 
     public Tag() 
     { 
      TagMaps = new List<ArticleTagMap>(); 
     } 

     public int Id { get; set; } 

     [Required, MaxLength(100)] 
     public string TagName { get; set; } 

     public virtual ICollection<ArticleTagMap> TagMaps { get; set; } 


    } 

public class ArticleTagMap : IEntityBase 
    { 


     public int Id { get; set; } 

     [Required] 
     public int ArticleId { get; set; } 
     [Required] 
     public int TagId { get; set; } 

     [ForeignKey("TagId")] 
     public virtual Tag Tag { get; set; } 

     [ForeignKey("ArticleId")] 
     public virtual Article Article { get; set; } 

    }

和DataContext的我添加以下代碼

protected override void OnModelCreating(ModelBuilder modelBuilder) 
{ 
    modelBuilder.Entity<ArticleTagMap>() 
       .HasOne(a => a.Tag) 
       .WithMany(b => b.TagMaps) 
       .HasForeignKey(c => c.TagId) 
       .OnDelete(DeleteBehavior.Cascade); 

      modelBuilder.Entity<ArticleTagMap>() 
       .HasOne(a => a.Article) 
       .WithMany(b => b.TagMaps) 
       .HasForeignKey(c => c.ArticleId) 
       .OnDelete(DeleteBehavior.Cascade); 
}

和SQL事件探查我趕上生成的腳本

exec sp_executesql N'SELECT [a0].[Id], [a0].[ArticleId], [a0].[ArticleId1], [a0].[TagId], [a0].[TagId1] 
FROM [ArticleTagMaps] AS [a0] 
INNER JOIN (
    SELECT DISTINCT TOP(1) [a].[Id] 
    FROM [Campaigns] AS [x] 
    INNER JOIN [Articles] AS [x.Article] ON [x].[ArticleId] = [x.Article].[Id] 
    INNER JOIN [Articles] AS [a] ON [x].[ArticleId] = [a].[Id] 
    WHERE [x.Article].[Slug] = @__slug_0 
    ORDER BY [a].[Id] 
) AS [a1] ON [a0].[ArticleId1] = [a1].[Id] 
ORDER BY [a1].[Id]',N'@__slug_0 nvarchar(4000)',@__slug_0=N'bantu-pekak-sanin'

有ArticleId1和TagId1列名這是不是availabl在桌上。我掙扎了好幾個小時，仍然沒有找到任何解決辦法。請幫助:)

您是如何解決這個問題的？看起來像一個錯誤，請回應。 –

-1

1）嘗試從OnModelCreating刪除.HasForeignKey() - 你已經在[ForeignKey(...)]屬性此信息（或刪除ArticleTagMap該屬性），並重新創建遷移腳本

2）你不需要在分析器中捕獲SQL。您可以檢查生成的遷移腳本（或整個模型的migrations/<DbContextName>DbModelSnapshot.cs文件）以確保EF「正確」理解您的模型
