Rails 5 compatibility

[spdawson]

In a clean Rails 5.0.0.beta1 project, adding

gem 'activeuuid'

to the Gemfile causes the following failure to start the server.

$ bundle exec rails s
DEPRECATION WARNING: alias_method_chain is deprecated. Please, use Module#prepend instead. From module, you can access the original method using super. (called from require at /var/lib/gems/2.2.0/gems/bundler-1.11.2/lib/bundler/runtime.rb:77)
/var/lib/gems/2.2.0/gems/bundler-1.11.2/lib/bundler/runtime.rb:80:in `rescue in block (2 levels) in require': There was an error while trying to load the gem 'activeuuid'. (Bundler::GemRequireError)

What happens if you run rails s without the bundle exec?

Also I currently see that warning and it is not a fatal error however I am using Nginx as a reverse proxy into Puma and it runs my web app fine.

[spdawson]

As you say, this is in fact just a warning. On further investigation, the real error in the logs is the following.

ActiveRecord::StatementInvalid (Mysql2::Error: Data too long for column 'id' at 
row 1: INSERT INTO `visits` (`id`, `visitor_id`, `ip`, `user_agent`, `landing_pa

I'm using activeuuid to support Ahoy with MySQL.

[daande]

This is actually a configuration issue on your end / Ahoy issue. You are trying to have an ID that is "x'63333263363761362d326534332d346139352d623764312d646535396263393739633864" which is too long for your column.

@spdawson What did you do to address this issue? I'm currently experience the same thing while attempting to upgrade an app to Rails 5. Any pointers would be appreciated.

[spdawson]

@emilford I was lucky in that ahoy no longer has a dependency on activeuuid; so I was just able to drop the activeuuid dependencies in my own Rails apps.

@spdawson I wish I would have read your message two hours ago. But, if anyone needs to use activeuuid with rails 5. (Or with Ruby 2.3) I started the work to remove all that alias_method_chain stuff that is causing errors. I got the code to run, but I didn't test it. All the changes are in the /lib/activeuuid/patches.rb file (attached as a .txt file)

My understanding is the included needs to be replaced with prepended. After that you can call super and avoid all that nasty alias_method_chain stuff. Again, I only got it to run without crashing. I didn't test it.
