如何使用 Identity 和 Entity Framework 与 AspNetUser 表建立一对一的关系

Question

在我的场景中，用户有一条船，而一条船有几个注释。

我正在使用默认的 Identity Mvc 项目模板，但我从未使用 Identity 与其他表建立任何关系。我只使用身份登录，没有任何关系

谁有任何关于如何将 aspNetUsers 表关联到其他表的示例？

船级

 public class Boat: Entity
    {

        public string Nome { get; private set; }
        public bool Ativo { get; private set; }    
        public bool Excluido { get; private set; }    
        public int SapId { get; private set; }    
        public int CapacidadeAgua { get; private set; }    
        public int CapacidadeOleo { get; private set; }    
        public int Velocidade { get; private set; }    
        public decimal AreaReal { get; private set; }    
        public decimal AreaProgramada { get; private set; }    
        public decimal AreaLivre { get; private set; }    
        public string Email { get; private set; }    
        public string Setor { get; private set; }   
        public DateTime DataCadastro { get; private set; }        
        public Guid? ClasseBarcoId { get; set; }

        public virtual ClasseBarco ClasseBarco { get; set; }

        public Barco(
            String nome, 
            bool ativo, 
            bool excluido, 
            int sapid, 
            int capacidadeAgua,
            int capacidadeOleo,
            int velocidade,
            string email,
            string setor,               
            DateTime dataCadastro)
        {
            Nome = nome;
            Ativo = ativo;
            Excluido = excluido;
            SapId = sapid;
            CapacidadeAgua = capacidadeAgua;
            CapacidadeOleo = capacidadeOleo;
            Velocidade = velocidade;
            Email = email;
            Setor = setor;
            DataCadastro = dataCadastro;

            ClasseBarco = new ClasseBarco();
        }
      }

这是一个例子，你会发现一对多的关系。

用户结构：

public class ApplicationUser : IdentityUser
{
    public ApplicationUser()
    {

        this.UserProducts = new HashSet<UserProduct>();

    }
    [Required]
    public string CompanyName { get; set; }
    [Required]
    public string ContactPerson { get; set; }
    [Required]
    public string ContactNumber { get; set; }
    [Required]
    public string PermanentAddress { get; set; }
    [Required]
    public string CorrespondenceAddress { get; set; }
    [Required]
    public string TIN { get; set; }
    public string PAN { get; set; }
    public string ServiceTaxNumber { get; set; }
    public string Category { get; set; }
    public virtual ICollection<UserProduct> UserProducts { get; set; }

    public ClaimsIdentity GenerateUserIdentity(ApplicationUserManager manager)
    {
        // Note the authenticationType must match the one defined in CookieAuthenticationOptions.AuthenticationType
        var userIdentity = manager.CreateIdentity(this, DefaultAuthenticationTypes.ApplicationCookie);
        // Add custom user claims here
        return userIdentity;
    }

    public Task<ClaimsIdentity> GenerateUserIdentityAsync(ApplicationUserManager manager)
    {
        return Task.FromResult(GenerateUserIdentity(manager));
    }
}

数据库上下文：

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

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

        public virtual DbSet<Category> Categories { get; set; }
        public virtual DbSet<Product> Products { get; set; }
        public virtual DbSet<Unit> Units { get; set; }
        public virtual DbSet<UserProduct> UserProducts { get; set; }
    }

实体框架中的一对一关系参考这里：
Configure One-to-Zero-or-One Relationship in Entity Framework 6

见下例：
我们将在以下Student 和StudentAddress 实体之间实现一对零或一的关系

public class Student
{
    public int StudentId { get; set; }
    public string StudentName { get; set; }

    public virtual StudentAddress Address { get; set; } //Can have only one address
}

public class StudentAddress 
{
    public int StudentAddressId { get; set; }
    public string Address1 { get; set; }
    public string Address2 { get; set; }
    public string City { get; set; }
    public int Zipcode { get; set; }
    public string State { get; set; }
    public string Country { get; set; }

    public virtual Student Student { get; set; }  //Single Student 
}
