@ -263,14 +263,25 @@ Creating superusers
-------------------
``manage.py syncdb`` prompts you to create a superuser the first time you run
it after adding ``'django.contrib.auth'`` to your ``INSTALLED_APPS``. But if
you need to create a superuser after that via the command line, you can use the
``create_superuser.py`` utility. Just run this command::
it after adding ``'django.contrib.auth'`` to your ``INSTALLED_APPS``. If you need
to create a superuser at a later date, you can use a command line utility.
**New in Django development version.**::
manage.py createsuperuser --username=joe --email=joe@example.com
You will be prompted for a password. Once entered, the user is created. If you
leave off the ``--username`` or the ``--email`` option, It will prompt you for
those values as well.
If you're using an older release of Django, the old way of creating a superuser
on the command line still works::
python /path/to/django/contrib/auth/create_superuser.py
Make sure to substitute ``/path/to/`` with the path to the Django codebase on
your filesystem.
Where ``/path/to`` is the path to the Django codebase on your filesystem. The
``manage.py`` command is prefered since it'll figure out the correct path and
environment for you.

**New in Django development version**
Creates a superuser account (a user who has all permissions). This is
useful if you need to create an initial superuser account but did not
do so during ``syncdb``, or if you need to programmatically generate
superuser accounts for your site(s).
When run interactively, this command will prompt for a password for
the new superuser account; when run non-interactively, no password
will be set and the superuser account will not be able to log in until
a password has been manually set for it.
The username and e-mail address for the new account can be supplied by
using the ``--username`` and ``--email`` arguments on the command
line; if not supplied, ``createsuperuser`` will prompt for them when
running interactively.
This command is only available if Django's `authentication system`_

Getting Help

How do I do X? Why doesn't Y work? Where can I go to get help?
--------------------------------------------------------------
If this FAQ doesn't contain an answer to your question, you might want to
try the `django-users mailing list`_. Feel free to ask any question related
to installing, using, or debugging Django.
If you prefer IRC, the `#django IRC channel`_ on freenode is an active
community of helpful individuals who may be able to solve your problem.

-----------------------------------------------
django-users_ has a lot of subscribers. This is good for the community, as
there are lot of people that can contribute answers to questions.
Unfortunately, it also means that django-users_ is an attractive target for
spammers.
In order to combat the spam problem, when you join the django-users_ mailing
list, we manually moderate the first message you send to the list. This means
that spammers get caught, but it also means that your first question to the
list might take a little longer to get answered. We apologize for any
inconvenience that this policy may cause.

Nobody on django-users answered my question? What should I do?
--------------------------------------------------------------
Wait. Ask again later. Try making your question more specific, or provide
a better example of your problem.
Remember, the readers of django-users_ are all volunteers. If nobody has
answered your question, it may be because nobody knows the answer, it may
be because nobody can understand the question, or it may be that everybody
that can help is extremely busy.
Resist any temptation to mail the `django-developers mailing list`_ in an
attempt to get an answer to your question. django-developers_ is for discussing
the development of Django itself. Attempts to use django-developers_ as
a second-tier support mechanism will not be met an enthusiastic response.

doesn't specify all the fields that are required by a model, the deserializer
will not be able to save deserialized instances.
Inherited Models
~~~~~~~~~~~~~~~~
If you have a model that is defined using an `abstract base class`_, you don't
have to do anything special to serialize that model. Just call the serializer
on the object (or objects) that you want to serialize, and the output will be
a complete representation of the serialized object.
However, if you have a model that uses `multi-table inheritance`_, you also
need to serialize all of the base classes for the model. This is because only
the fields that are locally defined on the model will be serialized. For
example, consider the following models::
class Place(models.Model):
name = models.CharField(max_length=50)
class Restaurant(Place):
serves_hot_dogs = models.BooleanField()
If you only serialize the Restaurant model::
data = serializers.serialize('xml', Restaurant.objects.all())
the fields on the serialized output will only contain the `serves_hot_dogs`
attribute. The `name` attribute of the base class will be ignored.
In order to fully serialize your Restaurant instances, you will need to
serialize the Place models as well::
all_objects = list(Restaurant.objects.all()) + list(Place.objects.all())
data = serializers.serialize('xml', all_objects)

different values:
* If ``value`` is an integer, the session will expire after that

``request.session.set_expiry(300)`` would make the session expire

* If ``value`` is a ``datetime`` or ``timedelta`` object, the
session will expire at that specific time.
* If ``value`` is ``0`` then the user's session cookie will expire
when their browser is closed.
