Cannot execute the rake uploads:migrate_from_s3

I’m going to have to stop using S3 for file uploads, and today I tried the rake uploads:migrate_from_s3, but it failed:

$ rake uploads:migrate_from_s3

I previously entered the container with the ./launcher enter app command, and listed the available tasks, and the migrate_from_s3 is nowhere to be found:

Am I doing something wrong or is it a bug?


Good catch, should be fixed per:


Another bug related to this rake task.

When executing the task, even tough I have the s3_upload_bucket set, the task fails with the following error: The S3 upload bucket must be set before running that task.

I am not sure why this is required @zogstrip don’t we already store full urls in the upload table?

That rake task’s logic hasn’t been updated in 4 years…

@Apecengo, can you try again with this newer version?


Doesn’t seem to be working as intended:

Migrating uploads from S3 to local storage for 'default'...

Each . should be a #, if i have understood correctly the code:

I’ve fixed the rake task to ensure we delete existing records before creating new ones (since we index based on the sha1 of the files, we weren’t able to create new records with the same sha1)
