   profile_obj = UserProfile.objects.get(user=user_obj)
      
   profile_obj.email_confirmed = False
   profile_obj.save() 
   .....my others code

class ChangePassword_link(View):
        #my others code....

        if user is not None and account_activation_token.check_token(user, token):
            profile_obj = UserProfile.objects.filter(user=user).update(email_confirmed = True)
            messages.success(request, ('Your account have been confirmed. Now you can login'))
            return redirect('members:change-password-page')
                
        else:
            messages.warning(request, ('The confirmation link was invalid, possibly because it has already been used.'))
            return redirect('members:change-password-page') 
        
       #my others code....
