title: Can I set up Cascade deleting in Rails?
body: <p>I know this is probably on the Internet somewhere but I can't find the answer here on Stackoverflow so I thought I may boost up the knowledge base here a little.</p>
  
  <p>I'm a newbie to Ruby and Rails but my company is getting pretty invested in it so I'm trying to get to know it in a little more detail.</p>
  
  <p>It's been difficult for me to change my mindset to designing an application from the "model" rather the from the database, so I'm trying to figure out how would do all of the design work that I have classically done in the Database in the Rails model instead.</p>
  
  <p>So the most recent task that I have given myself is to figure out how to configure a Rails database model to do cascading deletes? Is there an easy way of doing this? Or would I have to go into the MySql and set this up?</p>
