NameError on starting Rails application that does not use ActiveRecord

[ignisf]

Hi,

Disclaimer: I consider this to be outside of the normal way people use Rails, but I wanted to report it anyway. I am totally fine with you closing this as an unsupported use case :).

If one tries to use meta_request within a Rails app that explicitly does not load ActiveRecord, the following error gets raised:

          5: from /Users/xxx/.rbenv/versions/2.6.2/lib/ruby/gems/2.6.0/gems/meta_request-0.7.0/lib/meta_request/event.rb:66:in `block in transform_hash'
          4: from /Users/xxx/.rbenv/versions/2.6.2/lib/ruby/gems/2.6.0/gems/meta_request-0.7.0/lib/meta_request/event.rb:41:in `block in json_encodable'

          1: from /Users/xxx/.rbenv/versions/2.6.2/lib/ruby/gems/2.6.0/gems/bootsnap-1.4.1/lib/bootsnap/load_path_cache/core_ext/active_support.rb:8:in `without_bootsnap_cache'

It is caused due to the expression in the condition here attempting to load the ActiveRecord constant:

rails_panel/meta_request/lib/meta_request/event.rb

Lines 41 to 43 in 7b5af66

	elsif value.is_a?(ActiveRecord::ConnectionAdapters::AbstractAdapter)
	value = NOT_JSON_ENCODABLE
	end

Any solution for this?

Maybe check if ActiveRecord is defined (Object.const_defined?('ActiveRecord')) or compare ancestor names as strings?
