我正在尝试将个人资料/会员信息添加到我的MVC5应用程序中并添加配置映射.
我收到以下错误消息：
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());
}
}
解决方法
调用base.OnModelCreating(modelBuilder)并没有解决我的问题.
在VS2013-Preview,VS2013-RC和VS2013-RTM中,Microsoft.AspNet.Identity.EntityFramework的行为似乎不同.我正在使用RTM版本.
从IdentityUser继承之后,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; 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 });
}
(见Configuring/Mapping Properties and Types with the Fluent API)
我猜AspNet.Identity.EntityFramework的工作正在进行中,这将被修复(？)
