脚手架与Microsoft.AspNet.Identity在MVC 5

Question

我试图用脚手架和Microsoft.AspNet.Identity创建一个新的控制器，但我得到一个错误，指出 "IdentityUserLogin" has no key defined.

我试图创建一个客户表和Microsoft.AspNet.Identity用户表之间的关系。

我用来建立关系的字段是UserCreated,UserModified和UserAssigned。

的模型是：

[Table("Clients")] 
public partial class Client 
{ 
    [Key] 
    [DatabaseGeneratedAttribute(DatabaseGeneratedOption.Identity)] 
    public int Id { get; set; } 

    [Display(Name = "Criado em")] 
    [DisplayFormat(ApplyFormatInEditMode = true, DataFormatString = "{0:dd-M-yyyy HH:mm}")] 
    public DateTime DateCreated { get; set; } 

    [Display(Name = "Alterado em")] 
    [DisplayFormat(ApplyFormatInEditMode = true, DataFormatString = "{0:dd-M-yyyy HH:mm}")] 
    public DateTime DateModified { get; set; } 

    [MaxLength(128)] 
    public virtual string UserCreated_Id { get; set; } 

    [ForeignKey("UserCreated_Id")] 
    public virtual ApplicationUser UserCreated { get; set; } 

    [MaxLength(128)] 
    public virtual string UserModified_Id { get; set; } 

    [ForeignKey("UserModified_Id")] 
    public virtual ApplicationUser UserModified { get; set; } 

    [MaxLength(128)] 
    public virtual string UserAssigned_Id { get; set; } 

    [ForeignKey("UserAssigned_Id")] 
    public virtual ApplicationUser UserAssigned { get; set; } 

    [Required] 
    [MaxLength(256)] 
    [Display(Name = "Nome")] 
    public string Name { get; set; } 

    [Display(Name = "Morada")] 
    [MaxLength(512)] 
    public string Address { get; set; } 

    public int PostalCode { get; set; } 
    public int PostalCodeExtension { get; set; } 

    [MaxLength(256)] 
    public string PostalCodeCity { get; set; } 

    [Display(Name = "Telefone")] 
    [MaxLength(50)] 
    public string Telephone { get; set; } 

    [Display(Name = "Fax")] 
    [MaxLength(50)] 
    public string Fax { get; set; } 

    [Display(Name = "Email")] 
    [MaxLength(256)] 
    public string Email { get; set; } 

    [Display(Name = "Contribuinte")] 
    [MaxLength(50)] 
    public string VAT { get; set; } 
} 

Answer 1

可能是因为它是你如何定义ApplicationUser。我用下面的执行和它完美的作品 -

public class ApplicationUserLogin : IdentityUserLogin<int> 
{ 
} 

public class ApplicationUserRole : IdentityUserRole<int> 
{ 

} 

public class ApplicationUserClaim : IdentityUserClaim<int> 
{ 
} 

public class ApplicationUser : IdentityUser<int, ApplicationUserLogin, ApplicationUserRole, ApplicationUserClaim> 
{ 

} 

然后使用它像这样 -

public class DomainEntity : ..... 
{ 
    [Key] 
    public virtual int Id { get; set; } 
    public virtual ApplicationUser CreatedBy { get; set; } 

    public virtual ApplicationUser LastUpdatedBy { get; set; } 

} 

编辑：用户管理需要第二个参数，密钥类型。所以，改变它像 - 这

UserManager<ApplicationUser, int> 

和其他人 -

public class ApplicationDbContext : IdentityDbContext<ApplicationUser, ApplicationRole, int, ApplicationUserLogin, ApplicationUserRole, ApplicationUserClaim>
