Override migration methods to support UUID columns without having to be explicit about it.

ar-uuid's Issues

side effect in Rails 5: it breaks active_record.belongs_to_required_by_default = true

If you use ar-uuid to handle the uuid field typing for creating models and foreign key associations, a side effect is it breaks
Rails.application.config.active_record.belongs_to_required_by_default = true

In other words, for some reason the new Rails 5 default belongs_to validation (that ensures the child record contains the parent's id) is no longer run when an instance of the child is created or saved.

On the other hand, if you add the uuid typing manually instead of using the gem, the default belongs_to validation runs normally.

Unfortunately, as of Rails 5.0.1, which allows changing the default primary key to uuid without use of the ar-uuid gem, does not handle associations.

In our case we turn off the new Rails 5 belongs_to default validation, but I wanted to document this side-effect of the ar-uuid gem in case someone else is using it in Rails 5.

is it only needed when creating/running migrations (proposed ruby version issue workaround)

The dependency on ruby 2.1.0 or greater is unfortunate since 2.1 and 2.2 appear to be plagued with memory issues when running on Heroku.

For those of us still using Ruby 2.0 due to those memory issues, am I correct the gem is only used/needed in development, and only when creating migrations, and therefore it might be possible to temporarily upgrade ruby just when doing migrations but not when running the app? Eg, that there is no production behavior implemented in the gem?

I am hoping the following process might work (assuming the development machine uses rbenmv to manage both Ruby 2.0 and 2.1):

1. when creating and running a migration:
   a) specify ruby 2.1+ in Gemfile and
   b) un-comment the ar-rails gen,
   c) then re-run bundle install
2. create and run the migration
3. re-edit gemfile to specify ruby 2.0 again as needed for production and comment out the ar-rails gem and run bundle install again
