Orchard cms将data-mediapicker-uploadpath添加到自定义类型

Question

我在orchard cms中创建了一个自定义类型，它有两列布局

它有2个标题文本文件和2个内容HTML风格文件

继承迁移：

public class MigrationTwoColumnPageType : DataMigrationImpl
{
    public int Create()
    {
        // Define the project type 
        ContentDefinitionManager.AlterTypeDefinition("TwoColumnPage", cfg => cfg
            .WithSetting("Stereotype", "Content")
            .CommomPart()
            .AutoroutePart()
            .WithPart("TitlePart")
            .WithPart("MenuPart")
            .WithPart("TagsPart")
            .WithPart("PublishLaterPart")
            .WithPart("TwoColumnPage")
            .Creatable()
            .Draftable());

        return 1;

    }

    public int UpdateFrom1()
    {
        // Define project part - having a part with the same name will create fields in the project type
        ContentDefinitionManager.AlterPartDefinition("TwoColumnPage", builder => builder
           .TextField("Column1Title", Flavour.Large)
           .TextField("Column1Text", Flavour.Html)
           .TextField("Column2Title", Flavour.Large)
           .TextField("Column2Text", Flavour.Html)
           .Attachable());

        return 2;
    }   
}

注意：TextField是一种自定义扩展方法，可以减少冗长的内容

当我尝试使用媒体选择器将图像加载到其中一个内容字段中时，我得到一个找不到文件夹的错误， - 我已将其追溯到请求查询字符串未设置的媒体路径

// media directory to save uploaded files into
    var mediaPath = Request["uploadpath"];

in ../../ Orchard.MediaPicker / Views / admin / Tab_Url.cshtml

有没有办法使用字段设置来设置它？

似乎对我创建的任何页面都可以正常工作，但是自定义类型....如何设置此值？

更新

继承页面的xml元数据......

这是我的自定义类型的XML元数据，使用TestFiledSetting而不是BodyPartSetting

两者中都没有提到data-mediapicker-uploadpath。我还是迷路了！
