title: Override (save_model) in django admin for All models/apps in projects
body: <p>How could I implement override save method for all models in all Apps inside Admin panel?</p>
  <pre><code>def save_model(self, request, obj, form, change):
      
      pass
  </code></pre>
  <p>I can implement it in one or two models &quot;inherit and adding it in register method&quot;, but I really need it to execute whenever admin clicks save in Admin panel and implement some code before save.</p>
