我正在使用 ObjectEvents 根据用户填写的字段向当前用户提供 ActivityPoints。现在例如,如果用户注册并填写名字,我会给用户 10 分。问题是我正在处理 ObjectEvents.Update.After 并且在其中我正在更新 userSettings。这会导致无限循环并且应用程序停止工作。有什么解决办法吗?
这是代码块:
var className = e.Object.TypeInfo.ObjectClassName;
DataClassInfo dci = DataClassInfoProvider.GetDataClass(className);
if (dci != null)
{
var fi = new FormInfo(dci.ClassFormDefinition);
if (fi != null)
{
var stopProccess = true;
var fields = new List<FormFieldInfo>();
foreach (var changedColumn in e.Object.ChangedColumns())
{
var field = fi.GetFormField(changedColumn);
var activityPointMacro = ValidationHelper.GetString(field.Settings["ActivityPointMacro"], "");
if (!string.IsNullOrEmpty(activityPointMacro))
{
fields.Add(field);
stopProccess = false;
}
}
if (!stopProccess)
{
var contextResolver = CMSContext.CurrentResolver.CreateContextChild();
foreach (FormCategoryInfo info in fi.ItemsList.OfType<FormCategoryInfo>())
{
contextResolver.SetNamedSourceData(info.CategoryName, info);
}
EditingFormControl data = new EditingFormControl();
foreach (FormFieldInfo info2 in fi.ItemsList.OfType<FormFieldInfo>())
{
contextResolver.SetNamedSourceData(info2.Name, data);
}
foreach (var field in fields)
{
{
var activityPointMacro = ValidationHelper.GetString(field.Settings["ActivityPointMacro"], "");
var activityPoint =
ValidationHelper.GetInteger(contextResolver.ResolveMacros(activityPointMacro), 0);
CMSContext.CurrentUser.UserSettings.UserActivityPoints += activityPoint;
CMSContext.CurrentUser.UserSettings.Update();
}
}
}
}
}
