Defined in:
lib/active_record/refined/ast.rb

Overview

Whether a key is in the document. PostgreSQL's spelling is the ? operator rather than jsonb_exists, the function it is shorthand for, because a GIN index matches the operator and never the function. A ? is a bind placeholder only to sanitize_sql, which none of the SQL written here passes through.
