FluentNHibernate - 自动映射忽略属性 [英] FluentNHibernate - Automapping ignore property

问题描述

我有一个基类，其中包含一个名为IsDirty的属性。这用于域模型，不是数据库表中的列。

使用自动映射时，流利的nhibernate会尝试将此列添加到表中。一种解决这个问题的方法是在automapping设置中放置 .ForTypesThatDeriveFrom< Address>（p => p.IgnoreProperty（x => x.IsDirty）） / p>

问题是，我的所有实体都会这样做，有没有办法在不必为每个实体添加此行的情况下声明？如果我把 .ForTypesThatDeriveFrom< Entity>（p => p.IgnoreProperty（x => x.IsDirty）），那么当试图将Entity转换为地址。

我也有实体设置为基本类型。

在此先感谢，
JT创建一个从 DefaultAutomappingConfiguration 派生的类，然后重载





pre $ public class AutoMapConfiguration：DefaultAutomappingConfiguration
{
private static readonly IList< string> IgnoredMembers =新列表< string> {IsNew，IsDeleted};

public override bool ShouldMap（成员）
{
return base.ShouldMap（member）&& ！IgnoredMembers.Contains（member.Name）;






$ p

然后你的流畅配置看起来像这样： / b>



 流利的.Configure（）
 //数据库设置
 .Mappings（m => {
 m.AutoMappings.Add（yourMappingAssembly，new AutoMapConfiguration（））
}）; 
  




I have a base class that contains a property called IsDirty. This is used for the domain model and is not a column in the database table.

When using automapping, fluent nhibernate tries to add this column to the table. A way to fix this is to put .ForTypesThatDeriveFrom<Address>(p => p.IgnoreProperty(x => x.IsDirty)) in the automapping setup.

The problem is, all my entities will do this, is there a way to state this without have to add this line for every entity? If I put .ForTypesThatDeriveFrom<Entity>(p => p.IgnoreProperty(x => x.IsDirty)), then I get an error trying to convert Entity to Address.

I also have entity set as the base type.

Thanks in advance, JT

解决方案

You create a class derived from DefaultAutomappingConfiguration and override the ShouldMap(Member member) method.

Like so:

public class AutoMapConfiguration : DefaultAutomappingConfiguration
{
    private static readonly IList<string> IgnoredMembers = new List<string> {"IsNew", "IsDeleted"};

    public override bool ShouldMap(Member member)
    {
        return base.ShouldMap(member) && !IgnoredMembers.Contains(member.Name);
    }
}

and then your fluent configuration will look something like:

Fluently.Configure()
    // Database settings
    .Mappings(m => {
        m.AutoMappings.Add(yourMappingAssembly, new AutoMapConfiguration())
    });
