任何人都可以幫助我嗎?EF代碼 - 首先創建一些字段,即使我添加了ForeignKey註釋
這裏是我的2班
class Request
{
public Nullable<int> BuyCurrencyId {get ; set;}
public Nullable<int> SaleCurrencyId {get ; set;}
[ForeignKey("SaleCurrencyId")]
public virtual Currency SaleCurrency { get; set; }
[ForeignKey("BuyCurrencyId")]
public virtual Currency BuyCurrency { get; set; }
}
class Currency
{
public int Id { get; set; }
public string Name { get; set; }
public virtual ICollection<Request> Requests { get; set; }
public virtual ICollection<Request> Requests1 { get; set; }
}
我查了更新與EF數據庫,我發現了EF創建Reqyests
表是這樣的:
SaleCurrencyId int (Already exists)
BuyCurrencyId int (Already exists)
Currency_Id int (Added by EF)
Currency_Id1 int (Added by EF)
通過這不是事情我期望。我最後的兩列不正確,它們不存在。
任何人都可以幫助我嗎?
我使用EF 6個字母與T4.Please我生成的模型來更新現有的數據庫牢記這一點,我想用數據註解,不流利的API
對不起我的壞英語
更新1:
我想如果我改變貨幣類這將解決我的問題,但事實並非如此。
class Currency
{
public int Id { get; set; }
public string Name { get; set; }
[InverseProperty("SaleCurrencyId")]
public virtual ICollection<Request> Requests { get; set; }
[InverseProperty("BuyCurrencyId")]
public virtual ICollection<Request> Requests1 { get; set; }
}
