FOREIGN KEY 约束可能会导致循环或多个级联路径。 错误

Question

我有 4 个表 StokCard 表 StokGroup 表 GroupFeature 表和 StokCardAdditionalFeatureValue 表所有表都从 BaseModel 获取主键但我收到此错误

错误在这里

public class StokCard : BaseModel
{
        public string IPMKodu { get; set; }
        public int StokGroupId { get; set; }
        public StokGroup StokGroup { get; set; }
        ........................................ other properties
}

public class StokGroup:BaseModel
{
        public string GroupName { get; set; }
        public List<GroupFeature> GroupFeatures { get; set; }
        public List<StokCard> StokCards { get; set; }
}
public class GroupFeature : BaseModel
{
        public int StokGroupId { get; set; }
        public StokGroup StokGroup { get; set; }
        public List<StokCardAdditionalFeatureValue> StokCardAdditionalFeatureValues { get; set; }
}

public class StokCardAdditionalFeatureValue:BaseModel
{
        public int StokKartId { get; set; }
        public StokCard StokCard { get; set; }
        public int GroupFeatureId { get; set; }
        public GroupFeature GroupFeature { get; set; }
        public string FeatureValue { get; set; }
}

Answer 1

从StokCardAdditionalFeatureValue开始，我们至少有两个级联路径：

通过GroupFeater属性，然后我们引用StokGroup

通过StokCard ，然后通过StokGroup

您需要验证并清理您的数据库设计，以免导致此类循环。
