title: Django: Signal/Method called after "AppConfig.ready()"
body: <p>I have an <code>AppConfig.ready()</code> implementation which depends on the readiness of an other application.</p>
  
  <p>Is there a signal or method (which I could implement) which gets called after all application <code>ready()</code> methods have been called?</p>
  
  <p>I know that django processes the signals in the order of <code>INSTALLED_APPS</code>.</p>
  
  <p>But I don't want to enforce a particular ordering of <code>INSTALLED_APPS</code>.</p>
  
  <p>Example:</p>
  
  <pre><code>INSTALLED_APPS=[
     'app_a',
     'app_b',
     ...
  ]
  </code></pre>
  
  <p>How can "app_a" receive a signal (or method call) after "app_b" processed <code>AppConfig.ready()</code>?</p>
  
  <p>(reordering <code>INSTALLED_APPS</code> is not a solution)</p>
