Question

我需要帮助来从不同的页面更新Project的属性值。

我使用以下代码在“约会”页面中提取了属性值。

protected void FSAppointment_RowSelected(PXCache cache, PXRowSelectedEventArgs e, PXRowSelected InvokeBaseHandler)
    {
        if (InvokeBaseHandler != null)
            InvokeBaseHandler(cache, e);
        var row = (FSAppointment)e.Row;
        AppointmentEntry graph = (AppointmentEntry)cache.Graph;
        if (graph.ServiceOrderRelated.Current != null)
        {
            int? projectID = graph.ServiceOrderRelated.Current.ProjectID;
            ProjectEntry projectGraph = PXGraph.CreateInstance<ProjectEntry>();
            projectGraph.Project.Current = projectGraph.Project.Search<PMProject.contractID>(projectID);
            foreach (CSAnswers att in projectGraph.Answers.Select())
            {
                if (att.AttributeID == "ESTHOURS")
                {
                    cache.SetValueExt<FieldService.ServiceDispatch.FSAppointmentExt.usrProjectEstimatedRemainingHours>(row, att.Value);
                    return;
                }
            }
        }

    }

而且，现在我希望用户能够从“约会”页面更新该特定属性的值。

为此，我通过覆盖'约会'页面的Persist方法编写了以下代码。

public delegate void PersistDelegate();
    [PXOverride]
    public void Persist(PersistDelegate baseMethod)
    {
        if (Base.ServiceOrderRelated.Current != null)
        {
            using (PXTransactionScope scope = new PXTransactionScope())
            {
                int? projectID = Base.ServiceOrderRelated.Current.ProjectID;
                ProjectEntry projectGraph = PXGraph.CreateInstance<ProjectEntry>();
                var project = projectGraph.Project.Search<PMProject.contractID>(projectID);
                var answers = projectGraph.Answers.Select();
                foreach (CSAnswers att in answers)
                {
                    if (att.AttributeID == "ESTHOURS")
                    {
                        att.Value = "20";
                    }
                }
                projectGraph.Actions.PressSave();
            }

        }
        baseMethod();
    }

但它仍然没有更新价值。

要实现的是，属性系统与通常的DAC-＆gt; SQL系统不同。 CSAnswers是所有属性的非标准化值表。它们通过RefNoteID链接到DAC文档。请参阅CSAnswers中的select *，其中AttributeID =＆＃39; ESTHOURS＆＃39;在上面的代码中，您正在改变每个项目的时间＆＃39;。您还错过了一个语句，您可以通过该语句告诉图表使用您更改的对象更新缓存。像projectGraph.Answers.Update（att）;

之类的东西
