Overview

ActiveRecord constructs an Association from a Reflection and an Owner. It expects Owner to be an instance of an ActiveRecord object and uses ‘[]` to access specific values for fields on the record.

e.g. WHERE books.author_id = 7

We want to create a subquery that will reference those fields but not their specific values.

e.g. WHERE books.author_id = authors.id

So we create an object that serves the purpose of Owner but returns appropriate selectors.
