title: Best way to squash migrations django
body: <p>I had 10 migrations and I wanted to keep them in one file . So I squash them using  <code>./manage.py squashmigrations  accounts</code>  . Now I had  11  files including  init and squash file. so I deleted 9 other files and kept  init and squash and run <code>migration</code> and <code>migrate</code> .</p>
  <p>Now want to ask Is this proper way  ? and I have another app with same scenario should I do same to that ?</p>
