基于当前记录状态字段的自定义字段中的 Acumatica 动态下拉列表

Question

我在 BAccount 表中添加了一个名为 UsrSubStatus 的自定义字段，其中包含六个值的 PXStringList。如果 BAccount 状态字段为“Inactive”（值为 I），则 UsrSubStatus 下拉列表应仅允许选择列表值中的 3 个。如果状态字段不是非活动的，那么下拉列表应该只允许选择其他 3 个列表值。

我发现了一篇文章：Acumtica dynamic dropdown，看起来与我想要完成的内容非常相似，但它基于用户登录的当前公司的动态变化。

 var company = PX.Data.Update.PXInstanceHelper.CurrentCompany;

我在以下代码中的问题是如何在我的 var 状态行中引用 BAccount 状态字段。

 public class DynamicDropdownAttribute : PXStringListAttribute
 {
   #region Event Handlers
   private string[] Values2 = { "A1", "A2", "A3" };
   private string[] Labels2 = { "On-Plan", "Off-Plan", "Services Only" };

   private string[] Values3 = { "I1", "I2", "I3" };
   private string[] Labels3 = { "ROR - Same Product", "ROR - New Product", "Out of Business" };

   public DynamicDropdownAttribute()
       : base()
   {
   }

   public override void CacheAttached(PXCache sender)
   {
       base.CacheAttached(sender);
       var status = sender.CR.Status;
       if (status != "I")
       {
           this._AllowedValues = Values2;
           this._AllowedLabels = Labels2;
       }
       else 
       {
           this._AllowedValues = Values3;
           this._AllowedLabels = Labels3;
       }
   }
}

在此之后修改源代码，其中statusField 是您的自定义字段。在Customization Project Editor屏幕上，您应该为自定义字段设置CommitChanges=true。

 public class DynamicDropdown001Attribute : PXStringListAttribute
{
    public const string A1 = "On-Plan";
    public const string A2 = "Off-Plan";
    public const string A3 = "Services Only";

    public DynamicDropdown001Attribute() : base(new string[] { A1,A2,A3 }, new string[] { "On-Plan", "Off-Plan", "Services Only" }) { }
}
public class DynamicDropdown002Attribute : DynamicDropdown001Attribute
{
    public const string I1 = "ROR - Same Product";
    public const string I2 = "ROR - New Product";
    public const string I3 = "Out of Business";
    public DynamicDropdown002Attribute() 
    {
        Array.Resize(ref _AllowedValues, _AllowedValues.Length - 3);
        Array.Resize(ref _AllowedValues, _AllowedValues.Length + 3);
        _AllowedValues[_AllowedValues.Length - 3] = I1;
        _AllowedValues[_AllowedValues.Length - 2] = I2;
        _AllowedValues[_AllowedValues.Length - 1] = I3;
        Array.Resize(ref _AllowedLabels, _AllowedLabels.Length - 3);
        Array.Resize(ref _AllowedLabels, _AllowedLabels.Length + 3);
        _AllowedLabels[_AllowedLabels.Length - 3] = DynamicDropdown002Attribute.I1;
        _AllowedLabels[_AllowedLabels.Length - 2] = DynamicDropdown002Attribute.I2;
        _AllowedLabels[_AllowedLabels.Length - 1] = DynamicDropdown002Attribute.I3;
    }
}
public class DynamicDropdownAttribute : PXStringListAttribute, IPXRowSelectedSubscriber
{
    public Type _StatusField;
    public DynamicDropdownAttribute(Type statusField)
    {
        _StatusField = statusField;
    }
    public void RowSelected(PXCache sender, PXRowSelectedEventArgs e)
    {
        object row = e.Row as object;
        if (row != null)
        {
            bool? filter = (bool?)((string)sender.GetValue(e.Row, _StatusField.Name) == "I");
            PXStringListAttribute.SetList(sender, row, _FieldName, (filter.HasValue && filter.Value ? new DynamicDropdown001Attribute() : new DynamicDropdown002Attribute()));
        }
    }
}

我真的很喜欢第一个解决方案，并且能够从 Acumatica 获得一些帮助。第一步是定义 DAC：

[PXDBString(25, IsUnicode=true)]
[PXUIField(DisplayName="Sub-Status", Required = true)]
[PXDefault()]
[PXDependsOnFields(typeof(BAccount.status))]
[PXStringList(
new string[]
{ "A1", "A2", "A3", "I1", "I2", "I3" },
new string[]
{ "On-Plan", "Off-Plan", "Services Only", "ROR - Same Product", "ROR - New Product", "Out of Business" })]

然后在 BusinessAccountMaint_Extension 图中执行以下操作：

private string[] Values2 = { "A1", "A2", "A3" };
private string[] Labels2 = { "On-Plan", "Off-Plan", "Services Only" };
private string[] Values3 = { "I1", "I2", "I3" };
private string[] Labels3 = { "ROR - Same Product", "ROR - New Product", "Out of Business" };

protected void BAccount_Status_FieldUpdated(PXCache cache, PXFieldUpdatedEventArgs e, PXFieldUpdated del)
{
  if(del != null)
    del(cache, e);

  var row = (BAccount)e.Row;
  if(row == null) return;

  BAccountExt rowExt = PXCache<BAccount>.GetExtension<BAccountExt>(row);
  if (row.Status != "I")
      PXStringListAttribute.SetList<BAccountExt.usrSubStatus>(cache, row, Values2, Labels2);
  else
      PXStringListAttribute.SetList<BAccountExt.usrSubStatus>(cache, row, Values3, Labels3 );
}

protected void BAccount_RowSelected(PXCache cache, PXRowSelectedEventArgs e, PXRowSelected del)
{
  if (del != null)
    del(cache, e);

  var row = (BAccount)e.Row;
  if (row == null) return;

  if (row.Status != "I")
    PXStringListAttribute.SetList<BAccountExt.usrSubStatus>(cache, row, Values2, Labels2);
  else
    PXStringListAttribute.SetList<BAccountExt.usrSubStatus>(cache, row, Values3, Labels3);
}
