title: Django makemigrations No changes detected in app
body: <p>I have trouble with my makemigrations command.</p>
  
  <p>Note: I have successfully make migrations till now, so it is not the first time I try to make migrations on this project.</p>
  
  <p>I have my project in INSTALLED_APPS.</p>
  
  <p>Problem: For some reason project stop detecting any changes in my models. </p>
  
  <p>Inside my project models.py I have:</p>
  
  <pre><code>from myproject.myfolder import myModel1
  from myproject.myfolder import myModel2
  from myproject.myfolder import myModel3
  </code></pre>
  
  <p>if a add new models as myModel4 class and import it inside models.py and I try to </p>
  
  <pre><code>python mamange.py makemigrations environment=local
  </code></pre>
  
  <p>I get <code>No changes detected</code></p>
  
  <p>I know there are a lot of posts of making the initial migrations, so I even try </p>
  
  <pre><code>python manage.py makemigrations myproject environment=local
  </code></pre>
  
  <p>I even try to delete all files in <code>__pycache__</code> but it doesn't work for me. </p>
  
  <p>I even try to delete database and create new one, and it doesn't work either. </p>
  
  <h2>EDIT:</h2>
  
  <p>Because I delete the database and make it new again, database is empty, but I still get same message.</p>
