Module: CarrierWave::SafeRemove

Defined in:
lib/locomotive/carrierwave/patches.rb

Overview

FIXME: The carrierwave store_dir of the ContentEntry model was not correctly set up.

The consequence is the following bug:

  • context: a content entry has 2 file fields with 2 uploaded files sharing the same filename

  • action: we delete one of the 2 files.

  • result: the second file will be erased too.

The solution is to not delete a file if inside the same model, we find another file field sharing the same file identifier.
