NoMethodError: undefined method to_sym' for ["provider_id", "license_key", "facility_id"]:Array Did you mean? to_s to_set /Users/dewaynevanhoozer/.rbenv/versions/3.0.1/lib/ruby/gems/3.0.0/gems/rails-erd-1.7.2/lib/rails_erd/domain/attribute.rb:81:in block in foreign_key?'

Here is a possible solution ...

      def foreign_key?
        @domain
          .relationships_by_entity_name(@model.name)
          .map(&:associations)
          .flatten
          .map do |associaton|
            result = associaton.send(Domain.foreign_key_method_name)
            if result.class == Array
              result.join("_").to_sym
            else
              result.to_sym
            end
          end.include?(name.to_sym)
      end
