title: When to consider creating your own Ruby module in a Rails app?
body: <p>With a Ruby module, you can cluster together a bunch of methods that you might use in one place and then include them into a class so it's as if you had written them in that class. </p>
  
  <p><strong>What kinds of practical uses are there for Ruby modules in a rails app?</strong> </p>
  
  <p>I would appreciate if someone could mention an example of where they've actually used a module of their own so I have a sense of what situations I should be thinking about creating them. Thanks.</p>
