History


History storage displays the record field changes in all tables in the human-readable format.

You cannot create, edit, or delete records in the History (sys_history) table. Only users with the admin role can read them.

Navigate to the System Logs → History to access system history.

If you need to find specific records or to sort them in a particular order, use the condition builder to configure the filters that best suit your needs.

Use the audit.tables.ignoredList property to specify the tables whose changes will not be saved in history. 

Activity Feed History 

The Activity Feed widget displays history of field changes. It displays information about those fields, the value of which have been changed.

  • Previous values are in gray color. The new values are black.
  • Field changes are displayed according to the history display settings.

By selecting the tabs under the input field, you can filter out the displayed information.




To display changes of the specific fields in the History section instead of all fields changes, use the Available history fields handler functionality: 

  1. Click the three dots on the right to open the kebab menu.
  2. Click the Available history fields item.
  3. Clear the checkboxes of fields whose changes should not be shown in the activity feed.
  4. Click Apply.



If the history contains the fields that have been changed but are not selected in the Available history fields handler, they will be replaced by the No fields selected text.


Record Deletion Log


This log stores the information about deleted objects. You can also restore them with this log.

You cannot create and edit records in the Record Deletion Log (sys_record_deletion_log) table. Only users with the admin role can read and delete them.

Navigate to System Logs → Record Deletion Log to read the storage records.

Deletion logs are only available to tables with the selected Record Deletion Logging checkbox. See the Create Tables article to learn more.

If you need to find specific records or to sort them in a particular order, use the condition builder to configure the filters that best suit your needs.

FieldDescription
JSON

This field stores the attributes of the deleted record in JSON format as an associative massive.

{"sys_id": 162212096614481484, "title": "Smith", "sys_created_at": "2021-05-27 13:09:26", "sys_created_by": 155931135900000001, "sys_updated_at": "2021-05-27 13:09:26", "sys_updated_by": 155931135900000001}


Parent Record ID

The ID of the deleted record that caused the current record to be deleted: if record A causes record B to be deleted, this causes deletion of record C, then record C will display the ID of record A ID (as the original cause). 

This field is populated in case when the On Delete attribute of the reference column is Cascade. See the Reference Fields article to learn more.

Record IDThe ID of the deleted record.
Table NameTable name to which the deleted record belongs.
UsernameUser who initiated the record deletion.

Restore a record

To restore a record, perform the following steps:

  1. Navigate to System Logs → Record Deletion Log.
  2. Find the record you need using the list search or the condition builder:
    • select one or several records by checking the box on the left
    • open the record you need
  3. Click Restore.

The restored record will have the attributes described in the JSON field. The system restores the record version as it was before the deletion.


Records are restored independently of each other. For example, if deleting record A causes records B and C to be deleted, and then record A is restored, records B and C remain deleted. They should be restored additionally.
