======================================================
|
|
Breaking: #83153 - Migrated backend_layout.icon to FAL
|
|
======================================================
|
|
|
|
See :issue:`83153`
|
|
|
|
Description
|
|
===========
|
|
|
|
The existing database field "icon" for Backend Layouts put into the database, was previously a file upload field,
|
|
putting all icons under `uploads/media`. The field is migrated to the File Abstraction Layer (FAL), having
|
|
proper file relations like all other parts of TYPO3 core.
|
|
|
|
|
|
Impact
|
|
======
|
|
|
|
When working with the TCA for the backend_layout.icon field, sys_file_reference relations are now expected.
|
|
When querying the database table directly, icon only contains the number of references of this backend layout.
|
|
|
|
|
|
Affected Installations
|
|
======================
|
|
|
|
Installations with custom backend layout icons and, more specifically extensions dealing with the database
|
|
table directly.
|
|
|
|
|
|
Migration
|
|
=========
|
|
|
|
An upgrade wizard in the TYPO3 install tool moves all existing icons of backend_layouts from `uploads/media` to
|
|
`fileadmin/_migrated/backend_layouts/`.
|
|
|
|
For extensions directly working on the database table, the database access needs to be modified.
