我有以下型號實體框架的遷移:INSERT語句衝突與外鍵約束
public class User
{
public int UserID { get; set; }
public string FirstName { get; set; }
public string LastName { get; set; }
public string Email { get; set; }
public string FacebookID { get; set; }
public string GoogleID { get; set; }
public string TwitterID { get; set; }
public bool Admin { get; set; }
public bool Authorized { get; set; }
public virtual Comment Comment { get; set; }
public virtual CommentReply CommentReply { get; set; }
public virtual Project Project { get; set; }
public virtual ProjectVote ProjectVote { get; set; }
public virtual CommentReplyVote CommentReplyVote { get; set; }
public virtual CommentVote CommentVote { get; set; }
public virtual ProjectCoverVote ProjectCoverVote { get; set; }
}
public class Comment
{
[Key]
public int CommentID { get; set; }
public int ProjectDocID { get; set; }
public int UserID { get; set; }
public string Text { get; set; }
public string Annotation { get; set; }
public string Quote { get; set; }
public string Start { get; set; }
public string End { get; set; }
public string StartOffset { get; set; }
public string EndOffset { get; set; }
public DateTime DateCreated { get; set; }
public virtual ICollection<CommentVote> CommentVote { get; set; }
public virtual ICollection<CommentReply> CommentReply { get; set; }
public virtual ProjectDoc ProjectDoc { get; set; }
public virtual User User { get; set; }
}
然後我用這個作爲實體代碼首先遷移種子法的一部分:
context.Users.AddOrUpdate(i => i.FirstName,
new User { UserID = 1, FirstName = "Bob", LastName = "Dole", Email = "[email protected]", FacebookID = "123123124123", Admin = true, Authorized = true },
new User { UserID = 2, FirstName = "Dale", LastName = "Dole", Email = "[email protected]", FacebookID = "123123124123", Admin = false, Authorized = true }
);
context.Comments.AddOrUpdate(i => i.CommentID,
new Comment { CommentID = 1, ProjectDocID = 1, UserID = 1, Text = "This is a comment", DateCreated = DateTime.Parse("Dec 03, 2011 12:00:00 PM") }
);
這是我得到的錯誤。
System.Data.SqlClient.SqlException:
The INSERT statement conflicted with the FOREIGN KEY constraint
"FK_dbo.Comment_dbo.User_CommentID". The conflict occurred in database
"TEST_ba6946e96d174b7bac9543ba614c8cf8", table "dbo.User", column 'UserID'.
如果我註釋掉添加註釋行的嘗試,它對我的具有UserID字段的Projects表格有效。幫幫我?如果你發現任何不相關的錯誤或我應該知道的事情,請不要猶豫,指出它們。
難道是'User'有一個標識coulumn UserId',所以腳本中的值被忽略? (並且Id = 1的用戶已被刪除) –
您是否也在'Project'中插入'UserID = 1'? –
Gert,是的,有一個UserID = 1的項目行。 –
