sitecore - 将多列表字段映射到不同模板的对象

Question

我的项目有一个多列表字段，其中可以包含来自不同模板的项目。我想知道是否有任何方法可以映射此字段，以便根据模板将对象映射到正确的模型。例如:

public interface IPerson
{
    string FullName {get; set;}
}

[SitecoreType(TemplateId="....")]
public class Professor
{
    [SitecoreField]
    public string Prefix {get; set;}
    [SitecoreField]
    public string FirstName {get; set;}
    [SitecoreField]
    public string LastName {get; set;}

    public string FullName
    {
        return string.format("{0} {1} {2}", Prefix, FirstName, LastName)
    }
}

[SitecoreType(TemplateId="....")]
public class Student
{
    [SitecoreField]
    public string FirstName {get; set;}
    [SitecoreField]
    public string LastName {get; set;}

    public string FullName
    {
        return string.format("{0} {1}", FirstName, LastName)
    }
}

[SitecoreType(TemplateId="....")]
public class ClassSession
{
    [SitecoreField]
    public IEnumerable<IPerson> Participants {get; set;}
}

在本例中，我希望 Participants 属性包含 Student 和 Professor 对象，因为它们实现了 Fullname code> 属性不同。

您可以在 Glass.mapper 中使用推断类型，推断类型允许您根据正在加载的项目的模板加载更具体的类型。 :

public interface IPerson
{
    string FullName {get; set;}
}

[SitecoreType(TemplateId="....", AutoMap = true)]
public class Professor : IPerson
{
    [SitecoreField]
    public string Prefix {get; set;}
    [SitecoreField]
    public string FirstName {get; set;}
    [SitecoreField]
    public string LastName {get; set;}

    public string FullName
    {
        return string.format("{0} {1} {2}", Prefix, FirstName, LastName)
    }
}

[SitecoreType(TemplateId="....", AutoMap = true)]
public class Student : IPerson
{
    [SitecoreField]
    public string FirstName {get; set;}
    [SitecoreField]
    public string LastName {get; set;}

    public string FullName
    {
        return string.format("{0} {1}", FirstName, LastName)
    }
}

[SitecoreType(TemplateId="....", AutoMap = true)]
public class ClassSession
{
    [SitecoreField(Setting = SitecoreFieldSettings.InferType)]
    public IEnumerable<IPerson> Participants {get; set;}
}

请注意，我在您的类属性中添加了 AutoMap = true ，并将您的多列表属性更改为:

[SitecoreField(Setting = SitecoreFieldSettings.InferType)]

您需要将程序集包含在配置加载器中，在解决方案中找到 GlassMapperScCustom 类。然后您应该更新 GlassLoaders 方法:

public static IConfigurationLoader[] GlassLoaders()
    {
        var attributes = new AttributeConfigurationLoader("Your assembly name");

        return new IConfigurationLoader[] {attributes };
    }
