Having a field named 'created' within a model - Django

I have a model such as the following:

class Item(models.Model):

    name = models.CharField(max_length=150)
    created = models.DateTimeField(auto_now_add=True)

the admin class is the following:

class ItemAdmin(admin.ModelAdmin):

    list_display = ('name', 'created')

the created field does not seem to exist

Is there some basic Django knowledge that I am missing or have forgotten?

Just make sure not to forget registering the ItemAdmin in admin.py:

admin.site.register(Item, ItemAdmin)

However, the 'created' field would only be displayed in the Item's list page, as well as if you add an additional field such as:

updated = models.DateTimeField(auto_now=True)

Strange. I tried out your example and it worked perfectly well (Django 1.2.1, Python 2.6.2) Can you verify that:

  1. The field exists in the database (fire a SQL query perhaps)
  2. Check your admin.py (again) for any differences.

Update

@Daniel's answer is more likely to help the OP.

When you say the field does not exist, do you mean that it is not showing on the admin change form? This is expected behaviour when using auto_now_add. If you want the field to get a default value on creation but still be editable, use default=datetime.datetime.now instead.
