C# 将表与Microsoft Identity用户关联-没有键定义的错误
我遵循以下步骤,使用了C# 将表与Microsoft Identity用户关联-没有键定义的错误,c#,asp.net,asp.net-mvc-5,asp.net-identity-2,C#,Asp.net,Asp.net Mvc 5,Asp.net Identity 2,我遵循以下步骤,使用了ApplicationUser,而不是创建自己的应用程序应用程序用户来自默认的MVC 5应用程序: 这是我的应用程序用户代码: public class ApplicationUser : IdentityUser { public async Task<ClaimsIdentity> GenerateUserIdentityAsync( UserManager<ApplicationUser> manager ) {
ApplicationUser
,而不是创建自己的应用程序<代码>应用程序用户来自默认的MVC 5应用程序:
这是我的应用程序用户代码:
public class ApplicationUser : IdentityUser
{
public async Task<ClaimsIdentity> GenerateUserIdentityAsync( UserManager<ApplicationUser> manager )
{
// Note the authenticationType must match the one defined in CookieAuthenticationOptions.AuthenticationType
var userIdentity = await manager.CreateIdentityAsync( this, DefaultAuthenticationTypes.ApplicationCookie );
// Add custom user claims here
return userIdentity;
}
public virtual ICollection<Field> Fields { get; set; }
}
public class Field
{
[Key]
public int FieldID { get; set; }
// [ForeignKey( "Id" )] // Not sure if i needed this but neither worked
public virtual ApplicationUser CreatedBy { get; set; }
...
但是当我运行PM>addmigration AddedCreatedByToFields
时,会出现以下错误:
One or more validation errors were detected during model generation:
FieldApplication.Domain.Concrete.IdentityUserLogin: : EntityType 'IdentityUserLogin' has no key defined. Define the key for this EntityType.
FieldApplication.Domain.Concrete.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.
知道我做错了什么吗
旁注
我将我的ApplicationUser
代码移动到一个名为Domains的单独项目中。我包括Identity Nuget包以获取其中的名称空间…我最后放置了以下内容:
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 } );
modelBuilder.Entity().HasKey(l=>l.UserId);
modelBuilder.Entity().HasKey(r=>r.Id);
modelBuilder.Entity().HasKey(r=>new{r.RoleId,r.UserId});
在我的EFDbContext中:
protected override void OnModelCreating( DbModelBuilder modelBuilder )
{
// base.OnModelCreating( modelBuilder );
Precision.ConfigureModelBuilder(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 } );
}
模型创建时受保护的覆盖无效(DbModelBuilder modelBuilder)
{
//基于模型创建(modelBuilder);
精度。配置modelBuilder(modelBuilder);
modelBuilder.Entity().HasKey(l=>l.UserId);
modelBuilder.Entity().HasKey(r=>r.Id);
modelBuilder.Entity().HasKey(r=>new{r.RoleId,r.UserId});
}
然后我不得不运行迁移,然后创建了一整套新表。。。而我最终还是。。。我删除了默认表。没有人应答,因为代码似乎正确吗?如果是这样,这将帮助我找到问题:)
