title: overiding get_form() method to customize admin view according to user
body: <pre><code>def get_form(self, request, obj=None, **kwargs):
      if request.user.is_superuser:   
          self.exclude=[]
      else:
          self.fields=['employer_verified']
      return super(EmployerAdmin, self).get_form(request, obj, **kwargs)
  </code></pre>
  
  <p>i have this code to override the get_form() method to customize the view according to the user 
  it works just well when the super user login but the problem is when the staff member login and then the super user login only employer_verified is displayed i guess the problem is that 
  nothing is excluded from fields which is equal now to 'employer verified'</p>
