How to fix activeuuid gem error while upgrading from Rails4 to Rails5

Question

I am updating my application from rails 4 to rails 5. My application is using activeuuid gem. The activeuuid gem is using alias_method_chain internally and this method is deprecated in rails 5. Now when I am trying to start rails console, I am getting error -

undefined method `alias_method_chain' for ActiveRecord::ConnectionAdapters::Column:Class (NoMethodError)

Is there anyway I can continue using activeuuid gem in rails 5 and does not need to do any rework?

Answer 1

Rails 5 has built-in support for UUID primary keys, so ideally you should migrate away from this gem...

Try just delete this gem from your project and all must be fine.

However if you want to keep using this gem you can find (or create your own) fork. Last commit to original gem was 4 years ago (before rails 5 release). But I see forks where support for rails 5 was realized.

Since I didn't received any solution to this problem and after searching all around I came to below solution -

1. Removed the activeuuid gem from the application.
2. Implemented uuids with Ruby's SecureRandom class - Rails 5 Mysql UUID
3. In case if someone finds issue in saving record as activeuuid limits database column to 16 Bytes, one can use SecureRandom.hex(8).encode("UTF-8")
