Will v3 work with Rails 8?

[geoffharcourt]

Testing out an upgrade to Rails 8, and seeing that parameters designated in permit_params are not being marked as permitted. Is this going to be resolved in the v3 series, or will it be a requirement to upgrade to v4 to use Rails 8?

ActiveAdmin v3 does work with Rails 8 as part of our test suite in the 3-0-stable branch. Please submit a reproduction which you could probably do with our bug report template script. Thank you.

This is embarrassing, but we figured out that the reason we were seeing failures in Rails 8 was that in some cases we were passing an array of symbols into a permit_params declaration instead of a series of symbol arguments. In Rails 7 this would still work, but as of Rails 8 this causes the params to not be registered correctly as permitted.
