We have a number of places where we use the to_a method on the
return of an ActiveRecord find call. For instance:
people = Person.find(blah blah).to_a
This way, whether one or more Person objects are returned, "people"
is always an array of 0 or more elements.
I notice now though that I'm getting warnings:
warning: default 'to_a' will be obsolete
I believe this is from Ruby, and applies when an object does
not define its own to_a method. I believe this is only the case
when my find() happens to return 1 element (an ActiveRecord object
instead of an array of ActiveRecord objects), so I guess the
ActiveRecord objects are not defining their own to_a?
Is there a different "best practice" I might want to follow in the
above case so that I always have an array as a find() result?
Thanks!
