Описание: You build web applications, and you love Ruby on Rails because it provides
a framework for developing applications that are are fast, fun, and easy to change.
Over time these applications can become bloated, development slows down,
and changes to the codebase become painful.
This book was written to help you learn to detect emerging problems in your
codebase; we’ll deliver the solutions for fixing them, and maintaining an
application that will be fun to work on for years to come.
