EF 5，Fluent API：无效的列名“Source_ID”

Question

早上好

我获取无效的列名“Source_ID”。我的模特是：

产物：

public int ID { get; set; }
public string Name { get; set; }
public string Description { get; set; }
public decimal Price { get; set; }
public Nullable<decimal> PreviousPrice { get; set; }
public string Url { get; set; }
public int SourceID { get; set; }
public int SectionID { get; set; }
public int CategoryID { get; set; }
public Nullable<int> BrandID { get; set; }
public string PublisherProductID { get; set; }
public string PictureFilename { get; set; }
public bool Deleted { get; set; }
public Nullable<int> Score { get; set; }
public string EAN { get; set; }
public string ExtraAttributes { get; set; }
public DateTime LastUpdateDate { get; set; }

public virtual ICollection<FeedItem> FeedItems { get; set; }
public virtual ICollection<Sale> Sales { get; set; }
public virtual ICollection<ListProduct> ListProducts { get; set; }
public virtual ICollection<BonusMalus> BonusMalus { get; set; }
public virtual ICollection<ProductHunter> Hunters { get; set; }

来源：

public int ID { get; set; }
public string Name { get; set; }
public virtual ICollection<Product> Products { get; set; }
public virtual ICollection<SourceCategory> SourceCategories { get; set; }
public virtual ICollection<SourceCategoryRule> SourceCategoryRules { get; set; }
public virtual ICollection<WishlistGame> WishlistGames { get; set; }
public virtual ICollection<SourceWebsiteCommission> Commissions { get; set; }
public virtual ICollection<Sale> Sales { get; set; }

来源映射：

HasKey(e => e.ID);
Property(e => e.ID).HasDatabaseGeneratedOption(DatabaseGeneratedOption.None);
Property(e => e.Name).IsRequired().HasColumnType("VARCHAR").HasMaxLength(50);
ToTable("Sources");

表格产品＆amp;来源已经创建。当我运行我的解决方案时，我遇到了这个问题（无效的列名Source_ID）。也许这是我的映射中的错误。有人有解决方案吗？
