Question

我正在尝试将一个小部件添加到Orchard站点，我创建了一个继承自ContentPartRecord的新内容部分。它构建得很好，但是当我去运行Orchard.exe或者当我浏览到网站时，我收到了这个错误：

Exception Details: NHibernate.MappingException: Association references unmapped class: System.string

这是我的班级：

using System.ComponentModel.DataAnnotations;
using Orchard.ContentManagement;
using Orchard.ContentManagement.Records;
using System.Collections.Generic;

namespace Hjn.Models
{
public class PropertySearchRecord : ContentPartRecord
{
    public virtual List<string> PropertyTypes { get; set; }
    public virtual List<string> Locations { get; set; }
    public virtual List<double> MinimumPrices { get; set; }
    public virtual List<double> MaximumPrices { get; set; }
}

public class PropertySearchPart : ContentPart<PropertySearchRecord>
{
    [Required]
    public List<string> PropertyTypes
    {
        get { return Record.PropertyTypes; }
        set { Record.PropertyTypes = value; }
    }

    [Required]
    public List<string> Locations
    {
        get { return Record.Locations; }
        set { Record.Locations = value; }
    }

    [Required]
    public List<double> MinimumPrices
    {
        get { return Record.MinimumPrices; }
        set { Record.MinimumPrices = value; }

    }

    [Required]
    public List<double> MaximumPrices
    {
        get { return Record.MaximumPrices; }
        set { Record.MaximumPrices = value; }
    }
}
}

我很遗憾这个。如果你愿意，我也可以发布堆栈跟踪。请告诉我。谢谢！

Answer 1

是的，请勿使用List＆lt;＆gt;列的类型。相反，将它们作为n-n关系进行管理。有关于此的文档主题：http://docs.orchardproject.net/Documentation/Creating-1-n-and-n-n-relations

使用ContentPartRecord会导致运行时错误
