متى أحتاج لاستخدام $toReal داخل مسار الحقول في Entity Flow؟

Viewed 13

داخل تعريف الـ Entity Flow، عند كتابة مسار للوصول لحقل في ملف رئيسي مُشار إليه من خلال حقل مرجعي (مثل حقل "بناءً على" / From Document)، متى أحتاج إلى استخدام الكلمة $toReal ضمن المسار، ومتى يكفي استخدام النقطة . فقط؟

Inside an Entity Flow path:

  • If the field you want to reach belongs to a master file that is referenced through a generic reference field (for example From Document, which can point to several different entity types), you must use $toReal in the path to cast the generic reference to the actual target entity before continuing.
  • If the field is reached through a regular (typed) reference field, just use the dot . to navigate to it — no $toReal is needed.

In short: use $toReal only when crossing a generic reference; use . everywhere else.
