Question

我是MVC 5的新手，我正在尝试在创建的新数据库上下文中配置Individual User Auth，但ApplicationDBContext没有在我的新数据库中创建AspNetUser表。有人能指出我正确的方向吗？

错误

The entity type ApplicationUser is not part of the model for the current context.

IdentityModel.cs

public class ApplicationDbContext : IdentityDbContext<ApplicationUser>
{
    public ApplicationDbContext()
        : base("MyEntities", throwIfV1Schema: false)
    {
    }

    public static ApplicationDbContext Create()
    {
        return new ApplicationDbContext();
    }
}

的Web.config

<connectionStrings>
  <add name="DefaultConnection" connectionString="Data Source=(LocalDb)\MSSQLLocalDB;AttachDbFilename=|DataDirectory|\aspnet-MVC5.WebSite-20150723075149.mdf;Initial Catalog=aspnet-MVC5.WebSite-20150723075149;Integrated Security=True" providerName="System.Data.SqlClient" />
  <add name="MyEntities" connectionString="metadata=res://*/Models.UserModel.csdl|res://*/Models.UserModel.ssdl|res://*/Models.UserModel.msl;provider=System.Data.SqlClient;provider connection string=&quot;data source=devserver;initial catalog=MyEntities;user id=user;password=pass;MultipleActiveResultSets=True;App=EntityFramework&quot;" providerName="System.Data.EntityClient" />
</connectionStrings>

我知道MVC应该自动神奇地创建UserStore和相关表，但显然我在这里完成了一些非常愚蠢的事情。非常感谢任何帮助。

Answer 1

好吧，我做了一些愚蠢的事。基本上尝试让ApplicationDbContext使用由EF创建的连接。不是正确的方式。为了让表格“自动地”创建。我需要在连接到所需数据库的Web.config中添加一个普通的连接字符串，然后在IdentityModel.cs中设置它

<强>的Web.config

<connectionStrings>
  <add name="DefaultConnection" connectionString="Data Source=(LocalDb)\MSSQLLocalDB;AttachDbFilename=|DataDirectory|\aspnet-MVC.WebSite-20150723075149.mdf;Initial Catalog=aspnet-MVC.WebSite-20150723075149;Integrated Security=True" providerName="System.Data.SqlClient" />
  <add name="MyConnection" connectionString="Data Source=devserver;initial catalog=MyCatalog;user id=user;password=pass;Integrated Security=True" providerName="System.Data.SqlClient" />
 </connectionStrings>

<强> IdentityModel.cs

public class ApplicationDbContext : IdentityDbContext<ApplicationUser>
{
    public ApplicationDbContext()
        : base("MyConnection", throwIfV1Schema: false)
    {
    }

    public static ApplicationDbContext Create()
    {
        return new ApplicationDbContext();
    }
}

希望这有助于某人。感谢所有帮助过的人。

Answer 2

您是否使用代码优先迁移？

通常，您必须启用迁移，创建新迁移并应用它们才能创建数据库。

进入包管理器控制台并执行以下命令

enable-migrations
add-migration initial
update-database

修改

如果您不想使用迁移，您也可以将其放在上下文的构造函数中：

Database.SetInitializer<ApplicationDbContext>(new DropCreateDatabaseIfModelChanges<ApplicationDbContext>());

但每次重新创建数据库时都会丢失数据

Answer 3

 <add name="DefaultConnection" connectionString="Server=yourservername;Database=yourdbname;User Id=yourusername;Password=yourpassword;" providerName="System.Data.SqlClient" />

只需在web.config中创建此连接字符串然后运行应用程序，而不是注册帐户。现在检查你的数据库。

Answer 4

我首先使用数据库，修改了ExceptionLimeCat的答案，使其在我的系统上运行。如果答案未经修改，它将不会注册也不允许登录，也不会显示注册链接，也不会执行自动创建魔法，但会强制执行异常。这是对Web.config的修改以使其正常工作

<connectionStrings>
<add name="DefaultConnection" connectionString="data source=devserver;initial catalog=MyCatalog;user id=user;password=pass" providerName="System.Data.SqlClient" />
<add name="MyConnection" connectionString="metadata=res://*/Models.MyCatalog.csdl|res://*/Models.MyCatalog.ssdl|res://*/Models.MyCatalog.msl;provider=System.Data.SqlClient;provider connection string=&quot;data source=devserver;initial catalog=MyCatalog;user id=user;password=pass;MultipleActiveResultSets=True;App=EntityFramework&quot;" providerName="System.Data.EntityClient" />

这可能对那些发现上述答案复杂或有其他挑战的人有所帮助。

如果需要重新创建表，这是ASP.net EF 2.2的生成脚本
