在asp.net MVC5 EF6中使用流畅的api映射表？ [英] Map tables using fluent api in asp.net MVC5 EF6?

问题描述

我收到以下错误消息：

my.Models.IdentityUserLogin：：EntityType'IdentityUserLogin'没有定义
键。定义此EntityType的键。

my.Models.IdentityUserRole：：EntityType'IdentityUserRole'没有定义键
。定义此EntityType的密钥。

IdentityUserLogins：EntityType：EntitySet'IdentityUserLogins'是基于不定义键的类型IdentityUserLogin的
。 >

IdentityUserRoles：EntityType：EntitySet'IdentityUserRoles'是基于
的类型'IdentityUserRole'，没有定义键。

  public class ApplicationUser：IdentityUser 
 {
 public string City {get;组; } 
 public string Discriminator {get;组; } 
 
 public string Address {get;组; } 
} 
 
 public class ApplicationDbContext：IdentityDbContext< ApplicationUser> 
 {
 public ApplicationDbContext（）
：base（DefaultConnection）
 {
} 
 
 protected override void OnModelCreating（DbModelBuilder modelBuilder） 
 {
 modelBuilder.Configurations.Add（new ApplicationUserConfiguration（））; 
} 
} 
  

解决方案

base.OnModelCreating（modelBuilder）没有解决我的问题。

VS2013-Preview，VS2013-RC和VS2013-RTM中的Microsoft.AspNet.Identity.EntityFramework的行为似乎不同。我正在使用RTM版本。

继承自IdentityUser后，我不得不重新创建模型中的所有其他主键，使其工作：

  public class ApplicationUser：IdentityUser 
 {
 public string DisplayName {get;组; } 
} 
 
 
 public class ApplicationDbContext：IdentityDbContext< ApplicationUser> 
 {
 public ApplicationDbContext（）：base（DefaultConnection）{} 
 
 protected override void OnModelCreating（DbModelBuilder modelBuilder）
 {
 base.OnModelCreating （模型构建器）; 
 modelBuilder.Entity< IdentityUserLogin>（）。HasKey< string>（l => l.UserId）; 
 modelBuilder.Entity< IdentityRole>（）。HasKey< string>（r => r.Id）; 
 modelBuilder.Entity< IdentityUserRole>（）。HasKey（r => new {r.RoleId，r.UserId}）; 
} 
  

（请参阅使用Fluent API配置/映射属性和类型）

我猜在AspNet.Identity上工作。 EntityFramework正在进行中，这将被修复（？）

I am trying to add profile/Membership information into my MVC5 application and adding configuration mappings.

I get the following error message:

my.Models.IdentityUserLogin: : EntityType 'IdentityUserLogin' has no key defined. Define the key for this EntityType.

my.Models.IdentityUserRole: : EntityType 'IdentityUserRole' has no key defined. Define the key for this EntityType.

IdentityUserLogins: EntityType: EntitySet 'IdentityUserLogins' is based on type 'IdentityUserLogin' that has no keys defined.

IdentityUserRoles: EntityType: EntitySet 'IdentityUserRoles' is based on type 'IdentityUserRole' that has no keys defined.

public class ApplicationUser : IdentityUser
{
    public string City { get; set; }
    public string Discriminator { get; set; }

    public string Address { get; set; }     
}

public class ApplicationDbContext : IdentityDbContext<ApplicationUser>
{
    public ApplicationDbContext()
        : base("DefaultConnection")
    {
    }

    protected override void OnModelCreating(DbModelBuilder modelBuilder)
    {
        modelBuilder.Configurations.Add(new ApplicationUserConfiguration());           
    }
}

解决方案

Calling base.OnModelCreating(modelBuilder) did not solve the issue for me.

The behavior of Microsoft.AspNet.Identity.EntityFramework seems to be different in VS2013-Preview, VS2013-RC, and VS2013-RTM. I'm using the RTM version.

After inheriting from IdentityUser I had to recreate all other primary keys in the model to make it work:

public class ApplicationUser : IdentityUser
{
    public string DisplayName { get; set; }
}


public class ApplicationDbContext : IdentityDbContext<ApplicationUser>
{
    public ApplicationDbContext() : base("DefaultConnection") { }

    protected override void OnModelCreating(DbModelBuilder modelBuilder)
    {
        base.OnModelCreating(modelBuilder);
        modelBuilder.Entity<IdentityUserLogin>().HasKey<string>(l => l.UserId);
        modelBuilder.Entity<IdentityRole>().HasKey<string>(r => r.Id);
        modelBuilder.Entity<IdentityUserRole>().HasKey(r => new { r.RoleId, r.UserId });
    }

(See Configuring/Mapping Properties and Types with the Fluent API)

I guess work on AspNet.Identity.EntityFramework is ongoing and this will be fixed (?)
