instance method `to_ary`

Ruby on Rails 8.1.2

Since v5.2.8.1 Private

Available in: v5.2.8.1 v6.0.6 v6.1.7.10 v7.0.10 v7.1.6 v7.2.3 v8.0.4 v8.1.2

Compare with:

to_ary()

+Array#flatten+ will call #to_ary (recursively) on each of the elements of the array, and then rescues from the possible NoMethodError. If those elements are ActiveRecord::Base‘s, then this triggers the various method_missing’s that we have, which significantly impacts upon performance.

So we can avoid the method_missing hit by explicitly defining #to_ary as nil here.
