Subject: Avoid generating barcodes that are already in the database
X-Git-Url: https://old-git.evergreen-ils.org/?a=commitdiff_plain;h=ca49c2a77826b121e16c1317a8045b9d9e590b4c;p=contrib%2FConifer.git

Avoid generating barcodes that are already in the database

And complain when we get a colleague ID that is not the expected size.
