[英]Fluent NHibernate: Mapping a column with a different name
Let's say I have a table: 假设我有一张桌子:
Project
Id
Title
ProjectManagerId
ContactId
ProjectManagerId and ContactId are both id's from a table named Person: ProjectManagerId和ContactId都是来自名为Person的表的ID:
Person
PersonId
Firstname
Lastname
How can I map these two columns to create a person object? 如何映射这两列以创建人员对象? (either using automapping or fluent's normal mapping). (使用自动映射或fluent的法线贴图)。
Thanks 谢谢
Just create two classes as: 只需创建两个类即可:
public class Person
{
public virtual int PersonId { get; set; }
public virtual string FirstName { get; set; }
public virtual string Surname { get; set; }
}
public class Project
{
public virtual int ProjectId { get; set; }
public virtual string Title { get; set; }
public virtual Person ProjectManager { get; set; }
public virtual Person Contact { get; set; }
}
and a mapping class for Project as it is more interesting than Person :) 和Project的映射类,因为它比Person更有趣:)
public class ProjectMap : ClassMap<Project>
{
public ProjectMap()
{
Id(x => x.ProjectId);
Map(x => x.Title);
References(x => x.ProjectManager);
References(x => x.Contact);
}
}
if you are using FNH 如果您正在使用FNH
mapping override will be something like: 映射覆盖将类似于:
public class ProjectMappingOverride : IAutoMappingOverride<Project>
{
public void Override(AutoMapping<Project> mapping)
{
mapping.Id(x => x.ProjectId); //Usually for Id I have a convention, and not define it here
mapping.Map(x => x.Title); //Also for simple properties. You could remove these lines if you have setup the conventions.
mapping.References(x => x.ProjectManager);
mapping.References(x => x.Contact);
}
}
Do not forget about Convention other Configuration :) 不要忘记约定其他配置:)
好吧,我要做的就是创建一个名为“ Person”的视图,其中包含所需的数据,然后将其映射,就像普通表一样。
