看来EF不会创建这一个表
NotesModels.cs:
using System;
using System.Collections.Generic;
using System.ComponentModel.DataAnnotations;
using System.ComponentModel.DataAnnotations.Schema;
using System.Data.Entity;
using System.Globalization;
using System.Web.Security;
namespace note.DO.Models
{
public class NotesContext : DbContext
{
public NotesContext()
: base("DefaultConnection")
{
}
public DbSet<UserNotes> Notes { get; set; }
public DbSet<UserProfile> UserProfiles { get; set; }
}
[Table("UserNotes")]
public class UserNotes
{
[Key]
[DatabaseGeneratedAttribute(DatabaseGeneratedOption.Identity)]
public int NoteId { get; set; }
public virtual int UserId { get; set; }
[ForeignKey("UserId")]
public virtual UserProfile User { get; set; }
public string Title { get; set; }
public string Content { get; set; }
public DateTime? Added { get; set; }
public DateTime? Edited { get; set; }
}
public class CreateNoteModel
{
[Display(Name = "Author")]
public UserProfile Author { get; set; }
[Required]
[DataType(DataType.Text)]
[Display(Name = "Title")]
public string Title { get; set; }
[Required]
[DataType(DataType.MultilineText)]
[Display(Name = "Content")]
public string Content { get; set; }
[DataType(DataType.DateTime)]
[Display(Name = "Added on")]
public DateTime? AddedOn { get; set; }
}
}
我使用这些类生成了控制器。但是,当我尝试添加注释时,我会遇到以下异常:
无效的对象名称'dbo.UserNotes'。
......由此行触发:
db.SaveChanges();
我尝试过的事情:
有什么想法吗?也许我正在做一些非常愚蠢而没有注意到的事情?
编辑:UserProfile类和数据上下文:
public class UsersContext : DbContext
{
public UsersContext()
: base("DefaultConnection")
{
}
public DbSet<UserProfile> UserProfiles { get; set; }
}
[Table("UserProfile")]
public class UserProfile
{
[Key]
[DatabaseGeneratedAttribute(DatabaseGeneratedOption.Identity)]
public int UserId { get; set; }
public string UserName { get; set; }
public string Email { get; set; }
}
(...)
(other models)
答案 0 :(得分:1)
在阅读Gert Arnold的评论后,我做了这个
将此行添加到UsersContext:
public DbSet<UserNotes> Notes { get; set; }
所以这就是它现在的样子:
public class UsersContext : DbContext
{
public UsersContext()
: base("DefaultConnection")
{
}
public DbSet<UserProfile> UserProfiles { get; set; }
public DbSet<Notes> Notes { get; set; }
}
它完美无瑕!现在正在创建表,我可以毫无问题地添加条目。
