title: Django - makemigrations - No changes detected
body: <p>I was trying to create migrations within an existing app using the makemigrations command but it outputs "No changes detected".</p>
  
  <p>Usually I create new apps using the <code>startapp</code> command but did not use it for this app when I created it.</p>
  
  <p>After debugging, I found that it is not creating migration because the <code>migrations</code> package/folder is missing from an app. </p>
  
  <p>Would it be better if it creates the folder if it is not there or am I missing something?</p>
