Detailed Description

Restriction to make queries workspace-aware. This restriction ALWAYS fetches the live version plus in current workspace the workspace records. It does not care about the state, as this should be done by overlays.

As workspaces cannot be fully overlaid within ONE query, this query does the following:

  • ‪In live context, only fetch published records
  • ‪In a workspace, fetch all LIVE records and all workspace records which do not have "1" (= all new placeholders get fetched as well)

This means, that all records which are fetched need to run through either

  • ‪BackendUtility::getRecordWSOL() (when having one or a few records)
  • ‪PageRepository->versionOL()
  • ‪PlainDataResolver (when having lots of records)

Member Data Documentation

◆ $includeAllVersionedRecords

bool TYPO3\CMS\Core\Database\Query\Restriction\WorkspaceRestriction::$includeAllVersionedRecords

Used to also query records within a workspace, which is useful for DB queries that check for a specific field (e.g. "slug") which might have changed within a workspace. Please note that some duplicates might be shown and the "reduce" logic needs to be added after querying. Setting this flag might also be a problem when using the DB query with limit and offset settings.
