我无法理解为什么Glass Mapper无法以正确的方式投射对象,如here所述 我有下一堂课
public class BC
{
[SitecoreId]
public virtual ID Id { get; set; }
}
public class WB : BC
{
[SitecoreField(FieldName = "P1")]
public virtual Glass.Mapper.Sc.Fields.Link P1 { get; set; }
}
[SitecoreType(TemplateId = "{XXX}", AutoMap = true, EnforceTemplate = SitecoreEnforceTemplate.Template)]
public class AAA : WB
{
public virtual string AAAP1 { get; set; }
public virtual DateTime AAAP2 { get; set; }
}
[SitecoreType(TemplateId = "{VVV}", AutoMap = true, EnforceTemplate = SitecoreEnforceTemplate.Template)]
public class BBB : WB
{
public virtual string BBBp1 { get; set; }
public virtual DateTime BBBp2 { get; set; }
}
[SitecoreType(TemplateId = "{YYY}", AutoMap = true)]
public class RazorRenderClass: BC
{
[SitecoreChildren(InferType = true)]
public virtual IEnumerable<WB> Children { get; set; }
[SitecoreChildren(InferType = true)]
public virtual IEnumerable<AAA> AAACh { get; set; }
[SitecoreChildren(InferType = true)]
public virtual IEnumerable<BBB> BBBCh { get; set; }
}
在razor视图中,如果我使用Children属性
,我无法获得AAA或BBB对象 @foreach (var child in Model.Children)
{
if (child is BBB)
{
var news = child as BBB;
<li>
11
</li>
}
else if (child is AAA)
{
var evt = child as AAA;
<li>
222
</li>
}
}
更有趣的是,如果我在cshtml上使用对BBBCh或AAACh属性的调用,我可以看到(在调试时)Children属性包含正确的项目(对象)但是如果我尝试从Children属性中获取任何项目
var detailWidget = Model.Children.FirstOrDefault();
它会转向WB类。 我能用它做什么?

我遇到完全相同的问题,版本4.0.5.54。
我解决的问题是将子类型指定为属性,就像使用AAACh和BBBch一样。但是设置时没有延迟加载它们。
[SitecoreType(TemplateId = "{YYY}", AutoMap = true)]
public class RazorRenderClass: BC
{
[SitecoreChildren(InferType = true, IsLazy = false)]
public virtual IEnumerable<WB> Children { get; set; }
[SitecoreChildren(InferType = true, IsLazy = false)]
public virtual IEnumerable<AAA> AAACh { get; set; }
[SitecoreChildren(InferType = true, IsLazy = false)]
public virtual IEnumerable<BBB> BBBCh { get; set; }
}
我真的不喜欢我必须指定,AAACh和BBBch作为属性。在glassmapper v3中,以下就足够了。
[SitecoreType(TemplateId = "{YYY}", AutoMap = true)]
public class RazorRenderClass: BC
{
[SitecoreChildren(InferType = true)]
public virtual IEnumerable<WB> Children { get; set; }
}

我也遇到过这个问题。将它添加到GlassMapperScCustom的GlassLoaders方法中为我修复了它:
from multiprocessing import Pool
def updateDB(ip):
code goes here...
def my_view(request):
pool = Pool(processes=4) # process per core
pool.map(updateDB, ip)
return HttpResponse("SUCCESS")

添加配置加载器只能间歇性地为我修复它。基本上,任何时候w3wp都会循环,有些类型是正确的,有些类型是Castle Proxies。
我认为这是最新版本中的一个错误。
我的解决方法是使用代码重新绑定它:
protected List<ORM.IBaseModule> LocalModules;
protected void Page_Load(object sender, EventArgs e)
{
var contextItem = Sitecore.Context.Item;
var service = new SitecoreService(Sitecore.Context.Database.Name);
LocalModules = new List<ORM.IBaseModule>();
foreach (Item child in contextItem.Children)
{
if (child.TemplateID == ORM.AAAConstraints.TemplateId)
{
LocalModules.Add(service.Cast<ORM.AAA>(child));
}
//repeat for each type of child
}
