TimelineEntry

CRUD operations with timeline events are executed via \Bitrix\Crm\TimelineEntry. Each type of event has its own descendant, implementing the method create. This specific method is used for adding new events.

Service \Bitrix\Crm\TimelineEntry\Facade was designed for creating various types of events via unified entry point within [link=13967440]SPA[/link] timeline. This service simplifies code testing and gives an opportunity to mockup a desired behaviour.

Timeline event data is stored in three tables:


  1. b_crm_timeline (\Bitrix\Crm\Timeline\Entity\TimelineTable) - stores main data portion (event type, author, description and etc.).

    Fields ASSOCIATED_ENTITY_TYPE_ID and ASSOCIATED_ENTITY_ID describe, which element is described in the event. If element was created or updated, indicates this element. If an Activity was created, indicates this activity.

    The field TYPE_ID indicates an event type. Stores class constants \Bitrix\Crm\Timeline\TimelineType. Usually, each type of event has its own constant. However, several events can have the same value. For example, many types of "activities" have the same TYPE_ID = TimelineType::ACTIVITY.


  2. b_crm_timeline_bind (\Bitrix\Crm\Timeline\Entity\TimelineBindingTable) - stores data on which entity timelines must show the event. Has association as "single to multiple" with b_crm_timeline. Accordingly, the same event can be displayed in several timelines simultaneously.

  3. b_crm_timeline_search (\Bitrix\Crm\Timeline\Entity\TimelineSearchTable) - stores full-text index for searching by events.

When events are selected in the component crm.timeline to be rendered in element timeline with specific entityTypeId and entityId, filters by b_crm_timeline_bind.ENTITY_TYPE_ID = entityTypeId AND b_crm_timeline_bind.ENTITY_ID = entityId. All events, processed via this filter are displayed in the interface.
