title: hide secret key on django/pycharm mac
body: <p>I'm making a simple CRUD app in django with the use of Pycharm.</p>
  <p>I want to upload the project to Github and thus need to protect some of my settings.py file.</p>
  <p>Would the best way to be use a .env file and add it to .gitignore or does that method not work on mac?</p>
