Hi,

we’d love to use handcuffs with our application, and are currently trying to set it up.
Our application connects to two DBs, with different sets of migrations. When trying to run handcuffs' rake tasks, e.g. bundle exec rake 'handcuffs:migrate[pre_restart]' --trace, I get

** Invoke handcuffs:migrate (first_time)
** Invoke environment (first_time)
** Execute environment
** Execute handcuffs:migrate
** Invoke db:migrate (first_time)
** Invoke db:load_config (first_time)
** Invoke environment (first_time)
** Execute environment
** Execute db:load_config
** Execute db:migrate
rake aborted!
LoadError: cannot load such file -- db/migrate_other/20211026195842_create_handcuffs_other_tests.rb

Tasks: TOP => db:migrate

You can find the sample app that reproduces the issue (that the stack trace above is taken from) here: https://github.com/ariaru/test2dbs

We did experiment with auto loading and eager loading, but ran into issues with Zeitwerk: it complains about
migration constants starting with numbers (the timestamps).

Would you have any pointers as to how to fix this, or have you considered adding support for multiple DBs?

Thanks a lot!
