我目前正在 Oracle Linux 6 64 位虚拟机上使用 Alfresco 4.0.d 社区版（我也在 Alfresco 4.0.c 社区版上尝试过），使用 Firefox 作为我的浏览器。

最近，我一直在尝试创建一个脚本，该脚本可以通过在新项目进入空间/文件夹时动态创建子文件夹的规则来执行。

本质上，假设您有一个名为fileOne的新创建的内容。该文件将位于名为mainFolder的空间中，当在文件上运行规则以执行脚本时，脚本将根据文件的标题和作者值查看是否存在子文件夹。如果没有，它将根据该文件的标题值--> 子文件夹和作者值--> 子子文件夹在该mainFolder中创建子文件夹。然后我希望将该内容/文件移到现有或新创建的子文件夹中。

最终我想要的东西看起来像：

Space: mainFolder
|---> Content: fileOne --> Properties: Name, Title, Author
|---> Space: Title
      |---> Space: Author
            |---> Content: fileOne --> Properties: Name, Title, Author

下面是脚本...

function main()
{
    //mainFolder space/folder MUST exist under companyhome.
    var rootSpaceName = companyhome.childByNamePath("mainFolder");

    if(rootSpaceName == null)
    { 
        logger.log("Company Home/mainFolder does not exist, so we have nothing to do.");
        return;
    }
    else
    {
        logger.log("Company Home/mainFolder exists, so carry on our process.");

        var childList = rootSpaceName.children;
        var count = childList.length;
        var seconds = new Date().getTime() / 1000;

        if(count == 0)
        {
            logger.log("Company Home/mainFolder does not have child, nothing to do.");
            return;
        }
        else
        {
            for(var i = 0; i < count; i++)
            {
                // File Title MUST exist.
                var childTitle = childList[i].properties.title;

                if(childTitle == null)
                {
                    childTitle = "New Title " + seconds;
                }

                // File Author MUST exist.
                var childAuthor = childList[i].properties.author;

                if(childAuthor == null)
                {
                    childAuthor = "New Author " + seconds;
                }

                var child = childList[i];
                logger.log("This child is: " + child);

                if(child.isContainer == false)
                {
                    for(var j = 0; j < count; j++)
                    {
                        var newChildName = childList[j].properties.name;
                        logger.log("New child name: " + newChildName);
                        var newChild = childList[j];

                        if((newChild.isContainer == true) && (childTitle == newChildName))
                        {
                            var newSpaceName = rootSpaceName.childByNamePath(newChildName);
                            var newChildList = newSpaceName.children;
                            var newCount = newChildList.length;

                            for(var k = 0; k < newCount; k++)
                            {
                                var newNewChildName = newChildList[k].properties.name;
                                var newNewChildAuthor = newChildList[k].properties.author;
                                var newNewChild = newChildList[k];

                                if((newNewChild.isContainer == true) && (newNewChildAuthor == childAuthor))
                                {
                                    var currentSpace = newSpaceName.childByNamePath(newNewChildName);
                                    child.move(currentSpace);
                                }
                            }
                        }
                        else
                        {
                            // If title folder is already created, not need to create again.
                            var newSpaceName = companyhome.childByNamePath("mainFolder/" + childTitle);

                            if(newSpaceName == null)
                            {
                                newSpaceName = rootSpaceName.createFolder(childTitle);
                                logger.log("mainFolder/" + childTitle + " is created.");
                            }

                            // If author folder is already created, not need to create again.
                            var newNewSpaceName = companyhome.childByNamePath("mainFolder/" + childTitle + "/" + childAuthor);
                            if(newNewSpaceName == null)
                            {
                                newNewSpaceName = newSpaceName.createFolder(childAuthor);
                                logger.log("mainFolder/" + childTitle + "/" + childAuthor + " is created.");
                            }

                            child.move(newNewSpaceName);
                            logger.log("Moving file " + child.properties.name);
                        }

                    }

                }

            }
        }
    }
    return;
}

main();

所以为了测试这个，我一步一步地做：

  1. 我点击公司主页。
  2. 我点击Create，Create Space。
  3. 然后，我创建了一个名为mainFolder的空间（位于 Company Home 下）。
  4. 然后我单击新创建的文件夹，然后单击More Actions、Manage Content Rules。
  5. 然后我点击Create Rule。
    5a。它告诉我选择一个条件，我选择All Items，然后单击Add to List，然后单击Next。

    5b。现在它告诉我选择一个动作，我选择Execute Script，然后单击Set Values 和 Add，这允许我选择名为new-create-folders.js的脚本，我之前已将其添加到Data中的Scripts文件夹中字典。然后我单击确定，然后单击下一步。

    5c。在这里它要求我输入类型，我选择项目已更新。然后我输入一个标题，如创建文件夹规则。最后我在后台检查运行规则，然后点击下一步。

    5d。现在我单击完成以完成我的规则。
  6. 现在创建规则后，我单击Create，Create Content。

    6a。我给我的内容起一个名字，比如name001，然后我点击Next，然后我输入一个标题，比如title001和一个作者，比如author001。然后我点击OK。

现在发生的事情让我感到困惑；它像我想要的那样创建了一个名为title001的子文件夹，并在该子文件夹中创建了另一个名为author001的文件夹，并且在该文件夹中名为name001的文件已被移动。这就是我希望它工作的方式，但仍然存在问题。在mainFolder下，还有一个名为New Title 1346102873.393 New Title 1346102873.393的新子文件夹，其中有一个名为New Author 1346102873.393的文件夹，但该文件夹内没有文件。而且不知道为什么只在mainFolder中添加了一条内容就创建了这个文件夹? 此外，既然已经创建了文件夹，该规则看起来也已从mainFolder中删除，即不再有任何规则应用于该文件夹。当我返回在mainFolder上再次创建规则时，我收到错误：Failed to create Rule due to error: null. 以下是我在日志文件中遇到的错误...

有谁知道为什么要创建该附加文件夹，以及为什么在对新创建的内容执行该规则后要删除该规则，以及为什么在第一次删除原始规则后我无法向该文件夹添加新规则？

听起来您的规则运行了多次并且自己绊倒了。会不会是脚本本身正在执行的某些操作导致它再次运行？

检查您的规则是否未应用于子文件夹，而不是在向导的条件部分中选择“所有项目”，而是尝试更具体的内容，例如所有内容项目。

我在 Alfresco 论坛的同一张海报上发布了这个确切问题的答案。答案是代码尝试使用与文档相同的名称创建文件夹。节点必须在文件夹中唯一命名，因此这是不允许的。

实际上我认为的问题应该是规则被多次触发，条件规则“所有项目”正在更新。所以每个节点都会在存储库中收到更新，在带有规则的空间内（也许还有子文件夹，我会检查一下），它会触发并可能创建一个循环。您是否尝试过使用带有“创建节点时”触发器的规则？

更新：

因此，我尝试在 Alfresco 3.4.7 Enteprise 和 4.0 Community x64（Linux 和 Windows）上对此进行调试。

  • 我在 Alfresco 内的 Scripts 目录中创建了一个名为 /Company Home/Data Dictionary 的 js 文件。
  • 然后我在 Company Home 空间内创建了一个文件夹 mainFolder。
  • 我在文件夹 mainFolder 中上传了一个新的 PDF 文件。
  • 然后我对 PDF 文件执行 fs 文件。因此，进入文档的详细视图，然后单击“运行操作”-“执行脚本”。
  • 在那里，一切正常！

所以最后，问题出在规则执行中，它在“所有项目”上触发，因此，当脚本创建具有标题名称的新文件夹时，它会递归触发。我尝试使用“仅 PDF 类型”节点执行规则，它就像一个魅力！

希望这可以帮助...

可能您的要求是 mainFolder 中存在的文件具有标题和作者字段。您想将文件移动到标题->作者文件夹中。

就像那个 mainFolder -> FileName: file1, Title: title1, Author: author1

到 mainFolder -> title1 ->author1 ->file1

我尝试用我自己的代码编辑你的代码，并在 alfresco 端的 alfresco community 4.0c 中运行，并在 Windows 的共享端使用 java 脚本控制台。

为 mainFolder 创建规则时

1) 选择条件

1.1类型或子类型的内容作为选择条件

1.2内容作为设置条件值，不选中摘要下面的复选框 是项目是“内容”的子类型

2）选择与您相同的动作执行脚本

3) 创建或插入类型项目

我选择这些是因为动态运行我们的代码会创建文件夹。所以规则只适用于内容。除了取消选中后台执行规则外，其他与您相同。如果创建的项目没有标题名称，则 alfresco 默认假定项目名称为标题。

最后更新的代码：

function main()
{
    //mainFolder space/folder MUST exist under companyhome.
    var rootSpaceName = companyhome.childByNamePath("mainFolder");

    if(rootSpaceName == null)
    { 
        logger.log("Company Home/mainFolder does not exist, so we have nothing to do.");
        return;
    }
    else
    {
        logger.log("Company Home/mainFolder exists, so carry on our process.");

        var childList = rootSpaceName.children;
        var count = childList.length;

        if(count == 0)
        {
            logger.log("Company Home/mainFolder does not have child, nothing to do.");
            return;
        }
        else
        {
            for(var i = 0; i < count; i++)
            {   
                var child = childList[i];
                logger.log("This child is: " + child);

                // If each of child is file
                if(child.isDocument)
                {
                    // Get title of file and
                    // If childTitle is null, we set DEFAULT value
                    var childTitle = childList[i].properties.title;
                    if(childTitle == null)
                    {

该行：

 var rootSpaceName = companyhome.childByNamePath("mainFolder");

将尝试定位相对于companyhome存储库根目录的文件夹。该文件夹是否存在于您的存储库中？

如果您正在尝试编写一个对进入空间的文件进行操作的脚本，那么您是否不需要使用相对于该文件或空间的路径（使用documentorspace对象，而不是companyhome）？

如果没有，也许您可​​以多解释一下您要达到的目标？

如果您还没有使用它，那么 Alfresco JavaScript 控制台是一个非常有用的附加组件，用于尝试 JavaScript 代码，您可以使用logger.log().
