Tinymce Orchard cms将数据mediapicker上载路径添加到自定义类型

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

迁移过程如下：

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是一个自定义扩展方法，可以减少内容的冗余

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时，我得到一个“未找到文件夹”错误，-我已将其追溯到未设置请求查询字符串的媒体路径

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

在.././Orchard.MediaPicker/Views/admin/Tab_Url.cshtml中

是否有一些方法可以使用文件设置来设置此设置

似乎对我创建的任何页面都很好，但自定义类型。。。。如何设置此值

更新

这是一个页面的xml元数据

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

在这两个版本中都没有提到数据mediapicker上载路径。我还是迷路了

您应该能够通过导出有效类型的元数据，然后检查生成的xml文件来找到答案。
