Question

我是EF代码的新手，我试图强制ICollection导航属性使用我手动创建的特定关系表来映射实体。

我被迫这样做的原因是我的所有表都有一个TenantId列。这有可能吗？

[Table("Tenants")]
public class Tenant
{
    [Key, DatabaseGenerated(DatabaseGeneratedOption.Identity)]
    public int Id { get; set; }

    // This should use ContactAddressesForTenants table
    public virtual ICollection<Address> ContactAddresses {get; set;}

}

[Table("BusinessProfiles")]
public class BusinessProfile
{
    [Key, ForeignKey("Tenant")]
    public int TenantId { get; set; }

    public virtual Tenant Tenant { get; set; }

    // This should use the AddressesForBusinessProfiles table
    public virtual ICollection<Address> ProfileAddresses { get; set; }
}

[Table("Addresses")]
public class Address
{
    [Key, DatabaseGenerated(DatabaseGeneratedOption.Identity)]
    public int Id { get; set; }

    [ForeignKey("Tenant")]
    public int TenantId { get; set; }
}

[Table("ContactAddressesForTenants")]
public class ContactAddressForTenant
{
    [ForeignKey("Tenant")]
    public int TenantId { get; set; }

    [ForeignKey("Address")]
    public int AddressId { get; set; }

    public virtual Tenant Tenant { get; set; }

    public virtual Address Address {get; set;}
}

[Table("AddressesForBusinessProfiles")]
public class AddressForBusinessProfile
{
    [ForeignKey("BusinessProfile")]
    public int TenantId { get; set; }

    [ForeignKey("Address")]
    public int AddressId { get; set; }

    public virtual BusinessProfile BusinessProfile { get; set; }

    public virtual Address Address { get; set; }
}

如果我理解正确的话。您可以尝试在模型中更改此内容。

它在哪里：

// This should use ContactAddressesForTenants table
public virtual ICollection<Address> ContactAddresses {get; set;}
// This should use the AddressesForBusinessProfiles table
public virtual ICollection<Address> ProfileAddresses { get; set; }

更改为：

public virtual ICollection<ContactAddressForTenant> ContactAddresses {get; set;}
public virtual ICollection<AddressForBusinessProfile> ProfileAddresses { get; set; }

EF代码首先指定导航属性的关系表
