Applescript复制文件并添加到iTunes播放列表不工作

Question

我有问题试图从一个iTunes播放列表中追踪并添加到另一个新创建的，这用于现在工作它不，但我不知道如果它在所有或者只是在我的测试情况下不工作

这是我的测试：

tell application "iTunes" 
    set mainlibrary to library playlist 1 
    set list_of_folders to get every folder playlist 
    set new_playlistfolder to item 1 of list_of_folders 
    set new_playlist to (make user playlist in new_playlistfolder with properties {name:"TestPlayList"}) 
    try 
     set existtrack to (first file track of mainlibrary whose database ID = 14265) 
     duplicate existtrack to new_playlist 

    on error err_mess 
     log err_mess 
    end try 
end tell 

，这是我所得到的，当我在的AppleScript编辑器中运行它

tell application "iTunes" 
    get library playlist 1 
     --> library playlist id 14395 of source id 72 
    get every folder playlist 
     --> {folder playlist id 27010 of source id 72, folder playlist id 29459 of source id 72} 
    make with properties {name:"TestPlayList"} at folder playlist id 27010 of source id 72 new user playlist 
     --> user playlist id 29721 of source id 72 
    get file track 1 of library playlist id 14395 of source id 72 whose database ID = 14265 
     --> file track id 20505 of library playlist id 14395 of source id 72 
    copy file track id 20505 of library playlist id 14395 of source id 72 to user playlist id 29721 of source id 72 
     --> error number -1708 
    (*iTunes got an error: Can’t set user playlist id 29721 of source id 72 to file track id 20505 of library playlist id 14395 of source id 72.*) 
end tell 

任何想法。

Answer 1

我不是一个大的专家，但我有一个类似的脚本，而不是

(...) 
duplicate existtrack to new_playlist 
(...) 

我有：

(...) 
set t to (get location of existtrack) 
add t to new_playlist 
(...) 

它是否有助于？

Answer 2

我相信你需要写这行：

duplicate existtrack to new_playlist 

为：

duplicate existtrack to playlist new_playlist
