Question

我创建了一个需要创建额外MediaType的包，因为打包它在包屏幕中不可用。

为了避免这个问题，我开始研究通过Package Actions创建一个新的MediaType。最后开始关注此快速教程Umbraco V7 Compatible Packages

添加了一个类（下面），编译它（在调试模式下），将其复制到Umbraco的 / bin / 文件夹，然后将dll作为包文件添加，以及其他所有内容

然后，在另一个Umbraco实例上，从本地软件包安装它。

问题是：它不工作！

目前我不知道哪些是错的，所以如果有人有任何建议，欢迎他们。

以下是我创建的课程：

using System;
using System.Collections.Generic;
using System.Xml;
using umbraco.interfaces;

    {
        public string Alias()
        {
            return "SocialMediaChannels_AddThemes";
        }

        public bool Execute(string packageName, XmlNode xmlData)
        {
            string STEP = string.Empty;

            if (UmbracoVersion.Current.Major >= 7)
            {
                try
                {
                    #region MediaType
                    STEP = "Adding MediaType";

            }
            return false;
        }

        public bool Undo(string packageName, XmlNode xmlData)
        {
            if (UmbracoVersion.Current.Major >= 7)
            {
                //MediaType mediaType = new MediaType();
            }
            return true;
        }

        public XmlNode SampleXml()
        {
            var xml = string.Format("<Action runat=\"install\" undo=\"true\" alias=\"{0}\" />", Alias());
            XmlDocument x = new XmlDocument();
            x.LoadXml(xml);
            return x;
        }


    }
}

以下是助手类：

using System.Collections.Generic;
using Umbraco.Core.Models;

namespace Social_Media_Channels.Installer
{
    public class MediaHelper
    {
        private readonly static string MediaTypeName = "Social Media Theme";

        // LogHelper.Error<TranslationHelper>("Failed to add Opening Soon localization values to language file", ex);
        public static void AddMediaType()
        {
            MediaType mediaType = new MediaType(0);
            mediaType.AllowedAsRoot = true;
            mediaType.Name = MediaTypeName;
            mediaType.Description = "Container for the Social Media Channel Theme Images";
            mediaType.IsContainer = true;

            //Allowed child nodes
            var children = new List<ContentTypeSort>
                {
                    new ContentTypeSort(1031, 0),
                    new ContentTypeSort(1032, 1)
                };

            mediaType.AllowedContentTypes = children;

            //Add properties
            var name = new PropertyType(new DataTypeDefinition(-88, "themeName"));
            name.Name = "Theme Name";
            name.Description = "Name for the theme";

            var url = new PropertyType(new DataTypeDefinition(-88, "themeUrl"));
            url.Name = "Theme Url";
            url.Description = "Url for the original theme";

            var createdBy = new PropertyType(new DataTypeDefinition(-88, "createdBy"));
            createdBy.Name = "Created By";
            createdBy.Description = "Theme Author";

            var createdDate = new PropertyType(new DataTypeDefinition(-41, "createdDate"));
            createdDate.Name = "Created Date";
            createdDate.Description = "Date the Theme was created";

            mediaType.AddPropertyType(name, "Image");
            mediaType.AddPropertyType(url, "Image");
            mediaType.AddPropertyType(createdBy, "Image");
            mediaType.AddPropertyType(createdDate, "Image");
        }

        public static void RemoveMediaType()
        {

        }
    }
}

在Package Actions（Umbraco）中，我添加了以下行

<Action runat="install" undo="true" alias="SocialMediaChannels_AddThemes" />

建议或更正？任何人吗

通过与DAMP源代码（DAMP）进行比较，我注意到新的MediaType类 Umbraco.Core.Models.MediaType 缺少Save()方法，所以没有无论我如何测试，它根本不会保存新的媒体类型。

无论如何，通过使用DAMP的示例（旧的复制/粘贴），使用旧的程序集并显示消息'OBSOLETE'，提出了新版本的代码，如预期的那样。

旧库的代码是什么样的：

                folder.AllowedChildContentTypeIDs = folderStructure;

                MediaType image = MediaType.GetByAlias(MediaTypeName);

            mediaType.Save();

            return mediaType;
        }
    }
}

动作看起来像这样

<Action runat="install" undo="true" alias="SocialMediaChannels_AddSocialMediaThemes" ></Action>

原来我的原始代码出了很多问题。经过大量调查后终于搞定了。

基本上，添加（导致它失败）变为：

    public static void AddMediaType()
    {
        MediaType mediaType = new MediaType(-1);
        mediaType.AllowedAsRoot = true;
        mediaType.Name = NAME;
        mediaType.Description = "Container for the Social Media Channel Theme Images";
        mediaType.IsContainer = true;
        mediaType.Icon = "icon-picture";
        mediaType.Alias = ALIAS;

        //Allowed child nodes
        var children = new List<ContentTypeSort>
            {
                new ContentTypeSort(FOLDER_ID, 0),
                new ContentTypeSort(IMAGE_ID, 1)
            };

        mediaType.AllowedContentTypes = children;
        DataTypeService dataTypeService = (DataTypeService)ApplicationContext.Current.Services.DataTypeService;


        //Add properties
        var name = new PropertyType(dataTypeService.GetDataTypeDefinitionById(TEXT_ID), "themeName");
        name.Name = "Theme Name";
        name.Description = "Name for the theme";
        name.SortOrder = 0;

        var url = new PropertyType(dataTypeService.GetDataTypeDefinitionById(TEXT_ID), "themeUrl");
        url.Name = "Theme Url";
        url.Description = "Url for the original theme";
        url.SortOrder = 1;

        var createdBy = new PropertyType(dataTypeService.GetDataTypeDefinitionById(TEXT_ID), "createdBy");
        createdBy.Name = "Created By";
        createdBy.Description = "Theme Author";
        createdBy.SortOrder = 2;

        var createdDate = new PropertyType(dataTypeService.GetDataTypeDefinitionById(DATE_ID), "createdDate");
        createdDate.Name = "Created Date";
        createdDate.Description = "Date the Theme was created";
        createdDate.SortOrder = 3;

        mediaType.AddPropertyType(name, "Image");
        mediaType.AddPropertyType(url, "Image");
        mediaType.AddPropertyType(createdBy, "Image");
        mediaType.AddPropertyType(createdDate, "Image");

        ContentTypeService contentTypeService = (ContentTypeService)ApplicationContext.Current.Services.ContentTypeService;
        contentTypeService.Save(mediaType);
    }

现在它有效！

通过C＃创建新的MediaType（对于PackageAction）
