连接到其他模型的模型无法加载外键到代码 [英] Model connected to other models cannot load foreign keys to code

问题描述

以下模型类(预订)包含作为 ID 加载到数据库中的客户和露营地模型.但是，当我尝试检索所有这些预订的列表时，我无法访问与预订相关联的客户或营地信息.

The following model class(reservations) contains a customer and campingspot model which are loaded into the database as IDs. However when I try to retrieve a list of all these reservations I cannot acccess the customer or campspot information linked to the reservation.

public class Reservation
{


    [Key]
    public int ID { get; set; }

    [Required]
    public UserAccount Customer { get; set; }

    [Required]
    public CampingSpot CampSpot { get; set; }

我如何才能访问此信息，因为目前它始终是空值而不是 ID.

How would I make it possible to be able to access this information, because currently it is always a null value instead of an ID.

推荐答案

你想要的是

[RequiredNotDefault]
public int UserAccountId { get; set;}

[ForeignKey("UserAccountId")]
public virtual UserAccount Customer { get; set; }

CampingSpot 也一样

and the same for CampingSpot
