Question

我被困在弄清楚这一点。 MVC 5，EntityFramework 我的项目围绕着一项工作。每个Job都有多个ChangeOrders。我安装得很好。工作有一个客户。这也很好。我的问题在于客户员工。 Customer类与CustomerEmployee类具有一对多关系。每个Customer Employee都有一个基本属性和一个Role属性。超级，PM，会计或管理员。那么当我创建一份工作时，我需要选择一个CustomerEmployee Admin / PM等... 这会是什么关系？多对多的关系？在我看来，Job类需要有CustomerEmployeeSuperId，CustomerEmployeePMId，CustomerEmployeeAdminId和CustomerEmployeeAccountantId。

因为现在它只有CustomerEmployeeId

我该怎么做？当前设置

 public class Job
{
    //job
    public int JobId { get; set; }
    public int? JobNumber { get; set; }
    public string JobName { get; set; }
    public string JobDescription { get; set; }


    public int? GeoAreaId { get; set; }
    public virtual JobMisc.GeoArea GeoArea { get; set; }

    public int? JobClassId { get; set; }
    public virtual JobMisc.JobClass JobClass { get; set; }

    public int? JobTypeId { get; set; }
    public virtual JobMisc.JobType JobType { get; set; }

    public Int64? CustomerId { get; set; }
    public virtual Customer Customer { get; set; }

    public virtual ICollection<ChangeOrder> ChangeOrders { get; set; }
    public virtual ICollection<PurchaseOrder> PurchaseOrders { get; set; }

    public int? CustomerEmployeeId { get; set; }
    public virtual ICollection<CustomerEmployee> CustomerEmployees { get; set; }
}

public class Customer
{
   [Key]
    [DatabaseGeneratedAttribute(DatabaseGeneratedOption.None)]
   public Int64 CustomerId { get; set; }
    public string CustomerName { get; set; }
    public Int64? CustomerPhoneNumber { get; set; }
    public Int64? CustomerFaxNumber { get; set; }
    public string CustomerAddress { get; set; }
    public string CustomerCity { get; set; }
    public string CustomerState { get; set; }
    public int? CustomerZipcode { get; set; }
    public string CustomerWebsite { get; set; }
    public string CustomerOtherShit { get; set; }
    public bool? CustomerIsHidden { get; set; }

    public virtual ICollection<CustomerEmployee> CustomerEmployees { get; set; }
    public List<Job> Jobs { get; set; }
}

 public class CustomerEmployee
 {
    [Key]
    public int CustomerEmployeeId { get; set; }
    public string CustomerEmployeeFirstName { get; set; }
    public string CustomerEmployeeLastName { get; set; }
    public string CustomerEmployeeEmail { get; set; }
    public Int64? CustomerEmployeePhoneNumber { get; set; }
    public Int64? CustomerEmployeeCellNumber { get; set; }
    public Int64? CustomerEmployeeFaxNumber { get; set; }
    public bool? CustomerEmployeeIsHidden { get; set; }
    public string CustomerEmployeeRole { get; set; }

    public Int64? CustomerId { get; set; }
    public virtual Customer Customer { get; set; }

    public int? JobId { get; set; }
    public virtual ICollection<Job> Jobs { get; set; }
 }

那么，对于个人工作来说，这将是一对多的关系。对于多个工作，它可能是多对多。

作为管理员的员工是否可能会被作为某些工作的测试人员投入服务？

我建议为JobRoles创建一个子表，一个链接到JobID的表，一个CustomerEmployeeID和一个JobRoleID（假设JobRoles可以灵活处理）。

希望这会有所帮助......

我需要什么样的关系
