Can I use Django with Python 3?
-------------------------------
Not at the moment. Python 3.0 introduced a number of
backwards-incompatible changes to the Python language, and although
these changes are generally a good thing for Python's future, it will
be a while before most Python software catches up and is able to run
on Python 3.0. For larger Python-based software like Django, the
transition is expected to take at least a year or two (since it
involves dropping support for older Python releases and so must be
done gradually).
Django 1.5 introduces experimental support for Python 3.2 and 3.3. However, we
don't yet suggest that you use Django and Python 3 in production.
In the meantime, Python 2.x releases will be supported and provided
with bug fixes and security updates by the Python development team, so
continuing to use a Python 2.x release during the transition should
not present any risk.
Python 3 support should be considered a "preview". It's offered to bootstrap
the transition of the Django ecosystem to Python 3, and to help you start
porting your apps for future Python 3 compatibility. But we're not yet
confident enough to promise stability in production.
Our current plan is to make Django 1.6 suitable for general use with Python 3.

======================================
Customizing the Django admin interface
======================================
.. warning::
The design of the admin has changed somewhat since this document was
written, and parts may not apply any more. This document is no longer
maintained since an official API for customizing the Django admin interface
is in development.
Django's dynamic admin interface gives you a fully-functional admin for free
with no hand-coding required. The dynamic admin is designed to be
production-ready, not just a starting point, so you can use it as-is on a real
site. While the underlying format of the admin pages is built in to Django, you
can customize the look and feel by editing the admin stylesheet and images.
Here's a quick and dirty overview some of the main styles and classes used in
the Django admin CSS.
Modules
=======
The ``.module`` class is a basic building block for grouping content in the
admin. It's generally applied to a ``div`` or a ``fieldset``. It wraps the content
group in a box and applies certain styles to the elements within. An ``h2``
within a ``div.module`` will align to the top of the ``div`` as a header for the
whole group.
.. image:: _images/module.png
:alt: Example use of module class on admin homepage
Column Types
============
.. note::
All admin pages (except the dashboard) are fluid-width. All fixed-width
classes from previous Django versions have been removed.
The base template for each admin page has a block that defines the column
structure for the page. This sets a class on the page content area
(``div#content``) so everything on the page knows how wide it should be. There
are three column types available.
colM
This is the default column setting for all pages. The "M" stands for "main".
Assumes that all content on the page is in one main column
(``div#content-main``).
colMS
This is for pages with one main column and a sidebar on the right. The "S"
stands for "sidebar". Assumes that main content is in ``div#content-main``
and sidebar content is in ``div#content-related``. This is used on the main
admin page.
colSM
Same as above, with the sidebar on the left. The source order of the columns
doesn't matter.
For instance, you could stick this in a template to make a two-column page with
the sidebar on the right:
.. code-block:: html+django
{% block coltype %}colMS{% endblock %}
Text Styles
===========
Font Sizes
----------
Most HTML elements (headers, lists, etc.) have base font sizes in the stylesheet
based on context. There are three classes are available for forcing text to a
certain size in any context.
small
11px
tiny
10px
mini
9px (use sparingly)
Font Styles and Alignment
-------------------------
There are also a few styles for styling text.
.quiet
Sets font color to light gray. Good for side notes in instructions. Combine
with ``.small`` or ``.tiny`` for sheer excitement.
.help
This is a custom class for blocks of inline help text explaining the
function of form elements. It makes text smaller and gray, and when applied
to ``p`` elements within ``.form-row`` elements (see Form Styles below),
it will offset the text to align with the form field. Use this for help
text, instead of ``small quiet``. It works on other elements, but try to
put the class on a ``p`` whenever you can.
.align-left
It aligns the text left. Only works on block elements containing inline
elements.
.align-right
Are you paying attention?
.nowrap
Keeps text and inline objects from wrapping. Comes in handy for table
headers you want to stay on one line.
Floats and Clears
-----------------
float-left
floats left
float-right
floats right
clear
clears all
Object Tools
============
Certain actions which apply directly to an object are used in form and
changelist pages. These appear in a "toolbar" row above the form or changelist,
to the right of the page. The tools are wrapped in a ``ul`` with the class
``object-tools``. There are two custom tool types which can be defined with an
additional class on the ``a`` for that tool. These are ``.addlink`` and
``.viewsitelink``.
Example from a changelist page:
.. code-block:: html+django
<ul class="object-tools">
<li><a href="/stories/add/" class="addlink">Add redirect</a></li>
</ul>
.. image:: _images/objecttools_01.png
:alt: Object tools on a changelist page
and from a form page:
.. code-block:: html+django
<ul class="object-tools">
<li><a href="/history/303/152383/">History</a></li>
<li><a href="/r/303/152383/" class="viewsitelink">View on site</a></li>
</ul>
.. image:: _images/objecttools_02.png
:alt: Object tools on a form page
Form Styles
===========
Fieldsets
---------
Admin forms are broken up into groups by ``fieldset`` elements. Each form fieldset
should have a class ``.module``. Each fieldset should have a header ``h2`` within the
fieldset at the top (except the first group in the form, and in some cases where the
group of fields doesn't have a logical label).
Each fieldset can also take extra classes in addition to ``.module`` to apply
appropriate formatting to the group of fields.
.aligned
This will align the labels and inputs side by side on the same line.
.wide
Used in combination with ``.aligned`` to widen the space available for the
labels.
Form Rows
---------
Each row of the form (within the ``fieldset``) should be enclosed in a ``div``
with class ``form-row``. If the field in the row is required, a class of
``required`` should also be added to the ``div.form-row``.
.. image:: _images/formrow.png
:alt: Example use of form-row class
Labels
------
Form labels should always precede the field, except in the case
of checkboxes and radio buttons, where the ``input`` should come first. Any
explanation or help text should follow the ``label`` in a ``p`` with class
``.help``.

Many of Django's built-in class-based views inherit from other class-based
views or various mixins. Because this inheritence chain is very important, the
ancestor classes are documented under the section title of **Ancestors (MRO)**.
MRO is an acronym for Method Resolution Order.

Using a different template for each form
----------------------------------------
As mentioned above, you may specify a different template for each form.
Consider an example using a form wizard to implement a multi-step checkout
process for an online store. In the first step, the user specifies a billing
and shipping address. In the second step, the user chooses payment type. If
they chose to pay by credit card, they will enter credit card information in
the next step. In the final step, they will confirm the purchase.
Here's what the view code might look like::
from django.http import HttpResponseRedirect
from django.contrib.formtools.wizard.views import SessionWizardView
FORMS = [("address", myapp.forms.AddressForm),
("paytype", myapp.forms.PaymentChoiceForm),
("cc", myapp.forms.CreditCardForm),
("confirmation", myapp.forms.OrderForm)]
TEMPLATES = {"address": "checkout/billingaddress.html",
"paytype": "checkout/paymentmethod.html",
"cc": "checkout/creditcard.html",
"confirmation": "checkout/confirmation.html"}
def pay_by_credit_card(wizard):
"""Return true if user opts to pay by credit card"""
# Get cleaned data from payment step
cleaned_data = wizard.get_cleaned_data_for_step('paytype') or {'method': 'none'}
# Return true if the user selected credit card
return cleaned_data['method'] == 'cc'
class OrderWizard(SessionWizardView):
def get_template_names(self):
return [TEMPLATES[self.steps.current]]
def done(self, form_list, **kwargs):
do_something_with_the_form_data(form_list)
return HttpResponseRedirect('/page-to-redirect-to-when-done/')
...
The ``urls.py`` file would contain something like::
urlpatterns = patterns('',
(r'^checkout/$', OrderWizard.as_view(FORMS, condition_dict={'cc': pay_by_credit_card})),
)
Note that the ``OrderWizard`` object is initialized with a list of pairs.
The first element in the pair is a string that corresponds to the name of the
step and the second is the form class.
In this example, the
:meth:`~django.views.generic.base.TemplateResponseMixin.get_template_names()`
method returns a list containing a single template, which is selected based on
the name of the current step.

Argument `value` is handled differently in this method from the
subclasses of :class:`~Widget`.
If `value` is a list, output of :meth:`~MultiWidget.render` will be a
concatenation of rendered child widgets. If `value` is not a list, it
will be first processed by the method :meth:`~MultiWidget.decompress()`
to create the list and then processed as above.
Unlike in the single value widgets, method :meth:`~MultiWidget.render`

.. method:: decompress(value)
Returns a list of "decompressed" values for the given value of the
multi-value field that makes use of the widget. The input value can be
assumed as valid, but not necessarily non-empty.
This method **must be implemented** by the subclass, and since the
value may be empty, the implementation must be defensive.
The rationale behind "decompression" is that it is necessary to "split"
the combined value of the form field into the values of the individual
field encapsulated within the multi-value field (e.g. when displaying
the partially or fully filled-out form).

The default cannot be a mutable object (model instance, list, set, etc.), as a
reference to the same instance of that object would be used as the default
value in all new model instances. Instead, wrap the desired default in a

:meth:`~.QuerySet.exists` is useful for searches relating to both
object membership in a :class:`.QuerySet` and to the existence of any objects in
a :class:`.QuerySet`, particularly in the context of a large :class:`.QuerySet`.
The most efficient method of finding whether a model with a unique field
(e.g. ``primary_key``) is a member of a :class:`.QuerySet` is::
entry = Entry.objects.get(pk=123)
if some_query_set.filter(pk=entry.pk).exists():
print("Entry contained in queryset")
Which will be faster than the following which requires evaluating and iterating
through the entire queryset::
if entry in some_query_set:
print("Entry contained in QuerySet")
And to find whether a queryset contains any items::
if some_query_set.exists():
print("There is at least one object in some_query_set")
Which will be faster than::
if some_query_set:
print("There is at least one object in some_query_set")
... but not by a large degree (hence needing a large queryset for efficiency
gains).
Additionally, if a ``some_query_set`` has not yet been evaluated, but you know
that it will be at some point, then using ``some_query_set.exists()`` will do
more overall work (one query for the existence check plus an extra one to later
retrieve the results) than simply using ``bool(some_query_set)``, which
