考虑下面的模型/映射贫嘴多到许多不更新数据库时添加子
[DataContract]
public class CustomPhrase : ModelBase
{
private ICollection<EnglishPhrase> translations;
public CustomPhrase()
{
this.translations = new List<EnglishPhrase>();
}
[DataMember]
public virtual string Phrase { get; set; }
[DataMember]
public virtual IEnumerable<EnglishPhrase> Translations
{
get
{
return this.translations;
}
}
}
[DataContract]
public class EnglishPhrase : ModelBase
{
private ICollection<CustomPhrase> translations;
public CustomPhrase()
{
this.translations = new List<CustomPhrase>();
}
[DataMember]
public virtual string Phrase { get; set; }
[DataMember]
public virtual IEnumerable<CustomPhrase> Translations
{
get
{
return this.translations;
}
}
}
public CustomPhraseMap() : base("Translation_CustomPhrase", "CustomPhraseId")
{
this.Property(x => x.Phrase);
this.Set(
x => x.Translations,
map =>
{
map.Table("Translation_Link");
map.Key(key => key.Column("CustomPhraseId"));
map.Access(Accessor.Field);
map.Cascade(Cascade.All);
},
map => map.ManyToMany(c => c.Column("EnglishPhraseId"))
);
}
public EnglishPhraseMap() : base("Translation_EnglishPhrase", "EnglishPhraseId")
{
this.Property(x => x.Phrase);
this.Set(
x => x.Translations,
map =>
{
map.Table("Translation_Link");
map.Key(key => key.Column("EnglishPhraseId"));
map.Access(Accessor.Field);
map.Cascade(Cascade.All);
},
map => map.ManyToMany(c => c.Column("CustomPhraseId"))
);
}
如果我执行这段代码,实体被添加到数据库中,但链接表Translation_Link
不更新。
var customPhrase = new CustomPhrase { Phrase = "Gobble" };
var englishPhrase = new EnglishPhrase { Phrase = "Hello" };
customPhrase.AddTranslation(englishPhrase);
this.customPhraseRepository.Add(customPhrase);
我不确定这是映射问题还是存储库配置问题。也许我在错误的时间添加了孩子?
有没有其他人遇到过这个问题,并能够解决它?
这也是我最初的反应。我在这两个地图中都放入了Inverse(),并且得到以下错误 - “{”CustomPhrase.Translations和EnglishPhrase.Translations之间的关系在两侧都有指定的反向。从关系的一侧删除反向。“}'Remove a one .Inverse()函数的结果仍然相同。 – JConstantine
