Question

Django==1.8
django-audiofield==0.6.4
boto==2.38.0
django-storages==1.1.8

我目前在将音频文件上传到S3时遇到问题。正确上传所有图像。当我尝试上传音频时，我得到：异常类型：NotImplementedError 异常值：此后端不支持绝对路径。异常位置：... / lib / python2.7 / site-packages / django / core / files / storage.py在路径115行。

这是追溯的结束......

.../lib/python2.7/site-packages/audiofield/fields.py in _set_audio_converted
                    filename = self.generate_filename(instance, os.path.basename(getattr(instance, self.name).path)) ...


.../lib/python2.7/site-packages/django/db/models/fields/files.py in _get_path
                    return self.storage.path(self.name) ...


...c/lib/python2.7/site-packages/django/core/files/storage.py in path
                    raise NotImplementedError("This backend doesn't support absolute paths.") ...

我认为它也适用于

路径（名称）[来源]¶ 可以使用Python的标准open（）打开文件的本地文件系统路径。对于无法从本地文件系统访问的存储系统，这将引发NotImplementedError。

Answer 1

我有它工作......不完美但它有效。我需要重写部分django-audiofield fields.py。特别是def _rename_audio和def _set_audio_converted，因为它们都包含路径方法，如果您不从本地提供静态文件，则该方法不起作用。

在我的情况下，我收到此错误，因为我有一个额外的Save方法。

    [DllImport("user32.dll")]
    internal static extern uint SendInput(uint nInputs,  [MarshalAs(UnmanagedType.LPArray), In] INPUT[] pInputs, int cbSize);

    //main calling method
    public static void CLICK()
    {
        INPUT []i = new INPUT[1];

        i[0].type = 0;
        i[0].U.mi.time = 0;
        i[0].U.mi.dwFlags = MOUSEEVENTF.LEFTDOWN | MOUSEEVENTF.ABSOLUTE;
        i[0].U.mi.dwExtraInfo = UIntPtr.Zero;
        i[0].U.mi.dx = 1;
        i[0].U.mi.dy = 1;

        SendInput(1, i, INPUT.Size);
    }

    [StructLayout(LayoutKind.Sequential)]
    public struct INPUT
    {
        internal uint type;
        internal InputUnion U;
        internal static int Size
        {
            get { return Marshal.SizeOf(typeof(INPUT)); }
        }
    }

    [StructLayout(LayoutKind.Explicit)]
    internal struct InputUnion
    {
        [FieldOffset(0)]
        internal MOUSEINPUT mi;
        [FieldOffset(0)]
        internal KEYBDINPUT ki;
        [FieldOffset(0)]
        internal HARDWAREINPUT hi;
    }

    [StructLayout(LayoutKind.Sequential)]
    internal struct MOUSEINPUT
    {
        internal long dx;
        internal long dy;
        internal int mouseData;
        internal MOUSEEVENTF dwFlags;
        internal uint time;
        internal UIntPtr dwExtraInfo;
    }

    [Flags]
    internal enum MOUSEEVENTF : uint
    {
        ABSOLUTE = 0x8000,
        HWHEEL = 0x01000,
        MOVE = 0x0001,
        MOVE_NOCOALESCE = 0x2000,
        LEFTDOWN = 0x0002,
        LEFTUP = 0x0004,
        RIGHTDOWN = 0x0008,
        RIGHTUP = 0x0010,
        MIDDLEDOWN = 0x0020,
        MIDDLEUP = 0x0040,
        VIRTUALDESK = 0x4000,
        WHEEL = 0x0800,
        XDOWN = 0x0080,
        XUP = 0x0100
    }

我禁用了图像调整大小和保存方法后，错误消息消失了。

使用django-audiofield，django-storages，boto将音频文件上传到s3。 django-storages此后端不支持绝对路径错误
