django - Missing fields in the admin

I am trying to get the pub_date and the update option in the admin. But there's no such thing. In the admin there's only field for username, password and client ip. What am I missing? Your help will be very much appreciated. Thank you.

models:

class Member(models.Model):
    username = models.CharField(max_length=150)
    password = models.CharField(max_length=150)
    pub_date = models.DateTimeField(auto_now_add=True, auto_now=False)
    update = models.DateTimeField(auto_now_add=False, auto_now=True)

    def __unicode__(self):
        return self.username


class IP(models.Model):
    client_ip = models.CharField(max_length=50)
    pub_date = models.DateTimeField(auto_now_add=True, auto_now=False)
    update = models.DateTimeField(auto_now_add=False, auto_now=True)

Update:

from django.contrib import admin
from models import Member, IP
# Register your models here.

admin.site.register(Member)
admin.site.register(IP)

This is read-only field, so it is ignored by default in Django Admin. To show it, you have to define custom ModelAdmin class and specify it in fields atribute.

from django.contrib import admin
from models import Member, IP

class MemberAdmin(admin.ModelAdmin):
    fields = ('username', 'password', 'pub_date', 'update')

class IPAdmin(admin.ModelAdmin):
    fields = ('client_ip', 'pub_date', 'update')

admin.site.register(Member, MemberAdmin)
admin.site.register(IP, IPAdmin)

You can use fieldsets instead of fields to display fields in more sections (click).

I'm not aware of any options where you don't have to specify all fields to display.

PS: You can omit auto_now_add = False and auto_now = False as they are set to False by default.

@Selcuk is right, there is not much sense of editing the automatic fields, so django excludes datetime fields with auto_now* arguments from the admin.

If you really want to see these fields in admin then you have to change the model to mimic the auto_now* behavior:

from django.utils import timezone

class Member(models.Model):

    username = models.CharField(max_length=150)
    password = models.CharField(max_length=150)
    pub_date = models.DateTimeField(default=timezone.now)
    update = models.DateTimeField(default=timezone.now)

    def save(self, *args, **kwargs):
        if self.pk is None:
            self.pub_date = timezone.now()
        else:
            kwargs['update_fields'] = ['username', 'password', 'update']
        self.update = timezone.now()
        return super(Member, self).save(*args, **kwargs)

But note that if you will try to edit the fields your changes will be ignored.
