ruby 3.4 chilled string warning

[wlipa]

Running the latest release of rails_admin with the latest ruby 3.4 / rails gives a frozen string warning whenever the app starts.

$ ruby --version
ruby 3.4.1 (2024-12-25 revision 48d4efcb85) +PRISM [arm64-darwin24]

$ rails c
/Users/quxx/.gem/ruby/3.4.0/gems/rails_admin-3.3.0/lib/rails_admin/config/configurable.rb:60: warning: string returned by :queryable?.to_s will be frozen in the future

I found that this was due to calling:

class RailsAdmin::Config::Fields::Types::Json
  register_instance_option :queryable? do
    false
  end
end

in a rails initializer, and can be worked around like this:

class RailsAdmin::Config::Fields::Types::Json
  register_instance_option +'queryable?' do
    false
  end
end
