title: Ruby on Rails Convention over Configuration (CoC) Issues to scale Large Rails Project
body: <p>Working with Ruby on Rails for somewhile now. I'm enjoying it's builtin "Convention over Configuration" for small project. But, I'm little anxious about CoC application in Large Rails Projects.</p>
  
  <p>I know some pre built-in configuration raises more difficulty than ease, when need to scale the application in broad.</p>
  
  <p><b>What is those all specific Configurations will raise problem for me to scale? I will very grateful, if you please briefly explain those issues?</b></p>
