title: Django admin site is not showing default permissions of models
body: <p>My Django admin site does not show any default permissions of any models. Actually, I checked the database and I can't find any model permission in the <code>auth_permissions</code> table.</p>
  <p>I've already run <code>python manage.py makemigrations</code> and <code>python manage.py migrate</code>. I also tried deleting the database and migration files and run two above command again but doesn't work. I've already registered my models in admin.py.</p>
  <p>Any other solutions I can try ?</p>
  <p>admin.py</p>
  <pre><code>from django.contrib import admin
  from .Models import *
  
  
  # Register your models here.
  
  admin.site.register(LeaveRequest)
  admin.site.register(Worker)
  admin.site.register(TimeSheet)
