将图像上传到序列号

Question

我在InItemLotserial表中创建了一个自定义NOTEID字段，用于上传自定义页面中每个序列号的图像。它没有任何问题，工作正常。

我已经编写了一个处理页面来更新现有序列号的图像。

protected void AttachImage(InfoINItemLotSerialImport row, INItemLotSerial ser, InventoryItem itm)
    {
        string imageurl = row.ImageSourceUrl;
        string imageType = row.ImageType;
        string sRetVal = string.Empty;
        if (itm != null)
        {
            if (ser != null)
            {
                try
                {
                    WebClient wc = new WebClient();
                    byte[] buffer = wc.DownloadData(imageurl);
                    //MemoryStream ms = new MemoryStream(bytes);

                    string fileName = Path.GetFileName(imageurl);
                    fileName = string.Format("Serial Number attribute ({0} {1})\\{2}", itm.InventoryID, ser.LotSerialNbr, fileName);
                    PX.SM.FileInfo fileinfo = null;
                    PX.SM.UploadFileMaintenance filegraph = PXGraph.CreateInstance<PX.SM.UploadFileMaintenance>();
                    fileinfo = new PX.SM.FileInfo(fileName, null, buffer);
                    fileinfo.IsPublic = true;
                    if (filegraph.SaveFile(fileinfo))
                    {
                        ItemLotSerialMnt oLotSerMnt = PXGraph.CreateInstance<ItemLotSerialMnt>();
                        oLotSerMnt.lotserailrecdata.Current = ser;
                        oLotSerMnt.lotserial.Current = ser;
                        PXNoteAttribute.SetFileNotes(oLotSerMnt.lotserailrecdata.Cache, oLotSerMnt.lotserailrecdata.Current, fileinfo.UID.Value);
                        PXNoteAttribute.SetNote(oLotSerMnt.lotserailrecdata.Cache, oLotSerMnt.lotserailrecdata.Current, "");
                        sRetVal = fileinfo.Name;
                    }

                }
                catch
                {

                }
            }
        }
    }

它将数据上传到UploadFile表中，条目看起来很好。我可以使用URL访问图像，但这不会反映在序列页面的文件部分。

acumatica如何将文件与屏幕链接？

#region UsrNoteID
    public abstract class usrNoteID : PX.Data.IBqlField
    {
    }
    protected Guid? _UsrNoteID;
    [PXNote()]
    public virtual Guid? UsrNoteID
    {
        get
        {
            return this._UsrNoteID;
        }
        set
        {
            this._UsrNoteID = value;
        }
    }
    #endregion

Accumatica支持帮助我解决了这个问题。我错过了持续射击活动来保存。

            if (filegraph.SaveFile(fileinfo))
            {
                ItemLotSerialMnt oLotSerMnt = PXGraph.CreateInstance<ItemLotSerialMnt>();
                oLotSerMnt.lotserailrecdata.Current = ser;
                oLotSerMnt.lotserial.Current = ser;
                PXNoteAttribute.SetFileNotes(oLotSerMnt.lotserailrecdata.Cache, oLotSerMnt.lotserailrecdata.Current, fileinfo.UID.Value);
                PXNoteAttribute.SetNote(oLotSerMnt.lotserailrecdata.Cache, oLotSerMnt.lotserailrecdata.Current, "");
                sRetVal = fileinfo.Name;
                oLotSerMnt.Persist();
            }

<强> oLotSerMnt.Persist（）;
