title: Password field in django admin not displaying value
body: <p>I have a Crew Model. The table has a password field. I dont want to display password in plain text. So I have added forms where I have used <code>widget=forms.PasswordInput()</code>. But this doesnt display the password after saving the data. How do I display password in hidden format?</p>
  
  <pre><code>class Crew(models.Model):
       crew_id = models.AutoField(primary_key=True)
       crew_code = models.CharField(max_length=200, null=False, unique=True)
       crew_name = models.CharField(max_length=200, null=False)
       crew_password = models.CharField(max_length=200, null=False)
  </code></pre>
  
  <p>Forms.py</p>
  
  <pre><code>class UserForm(forms.ModelForm):
        crew_password = forms.CharField(widget=forms.PasswordInput())
  
        class Meta:
             model = Crew
             fields = ('crew_name', 'crew_password', 'crew_code', 'crew_id')
  </code></pre>
