我需要什么样的关系

Question

我被困在这个问题上。 MVC 5，EntityFramework 我的项目围绕着一个工作。每项工作都有多个ChangeOrders。我的设置很好。一份工作有一个客户。这工作也很好。我的问题是与客户员工。 Customer类与CustomerEmployee类具有一对多的关系。每位客户员工都具有基本属性和角色属性。超级，下午，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...... 这是什么关系？多对多的关系？在我看来，Job类需要有一个CustomerEmployeeSuperId，CustomerEmployeePMId，CustomerEmployeeAdminId和CustomerEmployeeAccountantId。

因为现在所有它是CustomerEmployeeId

我该怎么办呢？ 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; } 
} 

Answer 1

那么，对于个人工作，这将是一个一对多的关系。对于多个工作，它可能是多对多的。

作为管理员的员工是否有可能作为某些工作的测试员被服务？

我建议为JobRoles创建一个子表，其中一个链接到JobID，一个CustomerEmployeeID和一个JobRoleID（假设JobRoles的可能性是灵活的）。

希望这有助于...
