body: <p>let's suppose i have two models like below:</p>
  
  <pre><code>class Client(models.Model):
      login = models.CharField(max_length=100)
      password = models.CharField(max_length=100)
  
  class Users(models.Model):
      user_login = models.CharField(max_length=100)
      user_pass = models.CharField(max_length=100)
  </code></pre>
  
  <p>One model [Users] is filled with data, second [Client] is empty. First i can populate Client based on Users. Now all Django data changes will by held only on Client model.</p>
  
  <p><b>Question:</b></p>
  
  <p>How to dynamically connect this two models fields? For example if some data is changed on model Client then according data will by changed also on Users model.</p>
  
  <p><b>Solution suggestion:</b></p>
