Instance Method Details

#as ⇒ Object

Note:

This is necessary in order to ensure that when a translated attribute is selected with an alias using AS, the resulting expression can still be counted without blowing up.

Extending ::Arel::Expressions is necessary to convince ActiveRecord that this node should not be stringified, which otherwise would result in garbage SQL.
