在使用EF代码时,我会在不同时间收到以下错误:
实体类型SomeType不是当前上下文的模型的一部分.
导致此错误的可能原因是什么？
DB有一张桌子PackagingInfo.我有一Package节课,还有一节课ShopEntities : DbContext.
// Entity (ex. Package.cs)
[Table("PackagingInfo")]
public class Package
{
public decimal PackageID { get; set; }
public decimal Title { get; set; }
public decimal Cost { get; set; }
public bool isFree { get; set; }
}
// Entity Context (ex. ShopEntities.cs)
public class ShopEntities : DbContext
{
public DbSet<Package> Packages { get; set; }
}
// Controller Action (ex. HomeController.cs)
public ActionResult Index()
{
ShopEntities _db = new ShopEntities(); …我正在尝试将我的存储库更新为EF5,但遇到了一些错误.我已经看了一下stackoverflow,因为类似的错误发现了一些问题/答案,但不幸的是,相同的答案并没有解决我的问题.
这是我的错误:
The entity type User is not part of the model for the current context.
Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.
这是我的DbContext类:
public abstract class WebModelContext : DbContext
{
public WebModelContext()
: base("WebConnection")
{
Configuration.LazyLoadingEnabled = true;
}
}
这是继承我的WebModelContext类的上下文类:
public class AccountContext : WebModelContext
{
private DbSet<User> _users;
public AccountContext()
: …
