Migrate Private Files: FILE_EXISTS_REUSE still duplicate files

Question

I'm trying to migrate private files (file migration), the problem is even I set file_replace to 'FILE_EXISTS_REUSE' the files are still duplicated (it adds _1 or _2, and so on.). Here is my mapping:

    $this->addFieldMapping('file_replace')
         ->defaultValue('FILE_EXISTS_REUSE');
    $this->addFieldMapping('preserve_files')
       ->defaultValue(FALSE);

Please help!

Answer 1

This solved it for me. The documentation at this link has been updated to show that you need to use the class prefix:

$this->addFieldMapping('preserve_files')
  ->defaultValue(1);

$this->addFieldMapping('file_replace')
  ->defaultValue(MigrateFile::FILE_EXISTS_REUSE);

Answer 2

Maybe try:

$this->addFieldMapping('field_name', 'field_name');
$this->addFieldMapping('field_name:file_replace')->defaultValue(MigrateFile::FILE_EXISTS_REUSE);
