# Mounted uploaders are destroyed by carrierwave's after_commit
|
|
# hook. This hook fetches upload location (local vs remote) from
|
|
# Upload model. So it's necessary to make sure that during that
|
|
# after_commit hook model's associated uploads are not deleted yet.
|
|
# IOW we can not use dependent: :destroy :
|
|
# has_many :uploads, as: :model, dependent: :destroy
|
|
#
|
|
# And because not-mounted uploads require presence of upload's
|
|
# object model when destroying them (FileUploader's `build_upload` method
|
|
# references `model` on delete), we can not use after_commit hook for these
|
|
# uploads.
|
|
#
|
|
# Instead FileUploads are destroyed in before_destroy hook and remaining uploads
|
|
# are destroyed by the carrierwave's after_commit hook.
