# In the olden times (pre 4.1) files were all saved under the configured storage path,
|
|
# most likely `files`, with a timestamp attached to their name to avoid conflicts.
|
|
#
|
|
# e.g. `files/140917231758_openshift-setup.txt`
|
|
#
|
|
# The new approach is using CarrierWave for attachments. There the files will be stored
|
|
# some place else. Where is not material for this migration.
|
|
# It could be another directory or S3.
|
|
#
|
|
# The migration does the following:
|
|
#
|
|
# * rename the legacy files - it strips off the timestamps
|
|
# * assign the renamed file to the CarrierWave uploader - this moves the file to
|
|
# the new location
|
|
#
|
|
# The rollback does the opposite using the remaining legacy column `disk_filename`
|
|
# of Attachment. Meaning it adds the timestamp again and puts the files back into
|
|
# the configured attachment storage path.
|
|
#
|
|
# This assumes that the attachment storage path is the same as before the migration
|
|
# to CarrierWave and also that the legacy columns `filename` and `disk_filename`
|
|
# are still present.
