so I see appraisal here....we use it to help manage our rails updates and manage the dependencies different versions of rails. If properly installed, there should be an Appraisals file that declares versions (example here].

Also, please add the appropriate gemfiles to the test matrix in your workflow. This library is highly dependent on the rails behavior, so I recommend you add the target rails versions to CI. As per our current usage of rails, I recommend you add rails 6.1, 7.0, 7.1 and 7.2

Thanks y'all. I meant to circle back to this, but forgot.

activemodel and activesupport are a part of rails core -- so appraising rails at a different version than the ones declared here is declaring two different versions of the same package. Since you don't directly rely on all of rails, just these two modules, you can update appraisal so it's just declaring these modules instead. We can find time tomorrow to work with you on it if needed.

We can also work with you on how we release this. We don't normally take the time to send our pre-releases to rubygems, since we can just point to the github version.

@that-jill and @xjunior I think I've got Appraisal set up correctly. Should it be testing all packages on all pushes?

I tagged a version as v0.0.1pre4 that finally made it to rubygems.
