Exploring the magic behind dynamic finders: diving into ActiveRecord::Base.method_missing

This document discusses dynamic finders in ActiveRecord, which allow querying records using methods like find_by_first_name instead of writing raw SQL. It explores how ActiveRecord implements method_missing to dynamically define finder methods based on the query, and compares dynamic finders to regular method calls and messages. The document seeks to explain what dynamic finders are and how they work behind the scenes in ActiveRecord.
