title: What to do to run makemigrations/migrate on heroku when deploying changed models from github?
body: <p>I have deployed  app from github repository  to  the heroku account of my customer as collaborator but this time  I had to add some new models.</p>
  
  <p>However I realized that when I deploy my changes from github   heroku does not run makemigrations and migrate.</p>
  
  <p>I I read some answers on stackoverflow and understood this is how it is supposed to be. </p>
  
  <p>However my question is what should I do ? What is the best practise to deploy change models to heroku app. (I assume it is not deleting and recreating my app again since customer already has data there.)</p>
  
  <p>(I am able to run makemigrations and migrate from the bash manually but when I have 30+ deployments it's a pain)</p>
