FluentNhibernate HasMany与组件 [英] FluentNhibernate HasMany with component

问题描述

我有这个映射：

  HasMany< ClassA>（ot => ot.AList）
。 Table（XPTO）
 .KeyColumn（IDXPTO）
 .Component（m => 
 {
 m.Map（a => aX，X ）; 
 m.Map（x => xY，Y）; 
}）
 .Cascade.AllDeleteOrphan（）; 
  

我得到一个错误，提示引用了一个未映射的class classA，但是我不需要映射它。我在互联网上看到了类似映射的其他例子，他们没有这个问题...

如果我只为ID创建一个classMap classMap，那么它的工作，但数据模型将有一个不必要的表classA只有id，因为属性X和Y将被映射到表XPTO ...

解决方案

好的，未映射类的错误不是由于hasmany，而是我在那里有一个一对一地引用ClassA的其他属性。所以我有一对一的关系到classA和一对多，第一个是导致错误。
我解决了一对一的问题，然后工作。

i have this mapping:

    HasMany<ClassA>(ot => ot.AList)
        .Table("XPTO")
        .KeyColumn("IDXPTO")
        .Component(m =>
                        {
                            m.Map(a=> a.X, "X");
                            m.Map(x=> x.Y, "Y");
                        })
         .Cascade.AllDeleteOrphan();

i get an error saying that "refers to an unmapped class ClassA", but i shouldn't need to map it. i saw other examples in the internet with similar mappings and they don't have this problem...

if i create a classMap for class A only with ID, then its works, but the data model will have 1 unecessary table for classA with only the id, because property X and Y will be mapped on the table XPTO...

解决方案

ok, the error of unmapped class was not due to the hasmany, but to other property i had there that refered to ClassA on a one-to-one. So i had a one-to-one relatioshi to classA and a one-to-many, the 1st one was causing the error. I solved that one to one then it worked.
