title: Django-- Deactivate User account instead of deleting it
body: <p>I want to deactivate the User account instead of deleting it. I want to do something like user.is_active = False. I have a view to delete User profile and it works but now I need to change it to only deactivate. 
  Here is my view:</p>
  
  <pre><code>def delete_profile(request):
      user = User.objects.filter(id = request.user.profile.user_id)
      try:
          user.delete()
      except:
          messages.error(request,'Please try again.')
          return redirect('profile')
  
      messages.success(request, 'Profile successfully deleted.')
      return redirect('index')
  </code></pre>
  
  <p>I tried User.is_active = False , it displays the success message but doesn't do anything. When I check the User in admin panel it will still have User marked as active.</p>
  
  <p>Any Idea how I can achieve this? Thanks in advance</p>
