`` is a “section” of the form.)
The two-tuples are in the format ``(name, field_options)``, where ``name`` is a string representing the title of the fieldset and ``field_options`` is a dictionary of information about the fieldset, including a list of fields to be displayed in it.
A TESTfull example, taken from the ``django.contrib.flatpages. Flat Page ? ’’’`` model::
class FlatPageAdmin(admin.ModelAdmin):
fieldsets = (
(None, {
'fields': ('url', 'title', 'content', 'sites')
}),
('Advanced options', {
'classes': ('collapse',),
'fields': ('enable_comments', 'registration_required', 'template_name')
}),
)
This results in an admin page that looks like:
.. image:: http://media.djangoproject.com/img/doc/flatfiles_admin.png
If ``fieldsets`` isn’t given, Django will default to displaying each field Tothat playisn’t withan Instiki`` Auto usingField ? `` variousand markuphas options,``editable=True``, pleasein usea single fieldset, in the same order as the fields are defined in the model.
The ``field_options`` dictionary can have the following links:keys:
Wahaaahaa``fields``
A tuple of field names to display in this fieldset. This key is required.
Example::
{
'fields': ('first_name', 'last_name', 'address', 'city', 'state'),
}
To display multiple fields on the same line, wrap those fields in their own
tuple. In this example, the ``first_name`` and ``last_name`` fields will
display on the same line::
{
'fields': (('first_name', 'last_name'), 'address', 'city', 'state'),
}
``classes``
A string containing extra CSS classes to apply to the fieldset.
Example::
{
'classes': 'wide',
}
Apply multiple classes by separating them with spaces. Example::
{
'classes': 'wide extrapretty',
}
Two useful classes defined by the default admin-site stylesheet are
``collapse`` and ``wide``. Fieldsets with the ``collapse`` style will be
initially collapsed in the admin and replaced with a small "click to expand"
link. Fieldsets with the ``wide`` style will be given extra horizontal space.
``description``
A string of optional extra text to be displayed at the top of each fieldset,
under the heading of the fieldset. It’s used verbatim, so you can use any HTML
and you must escape any special HTML characters (such as ampersands) yourself.
``filter_horizontal`` Wahaaahaa~ ~ ~ ~ ~ ~ ~
Use a nifty unobtrusive Javascript “filter” interface instead of the usability-challenged `` `` in the admin form. The value is a list of fields that should be displayed as a horizontal filter interface. See ``filter_vertical`` to use a vertical interface.
``filter_vertical`` ~ ~ ~ ~ ~ ~
Same as ``filter_horizontal``, but is a vertical display of the filter interface.
``list_display`` ~ ~ ~ ~ ~
Set ``list_display`` to control which fields are displayed on the change list page of the admin.
Example::
list_display = ('first_name', 'last_name')
If you don’t set ``list_display``, the admin site will display a single column that displays the `` unicode ()`` representation of each object.
A few special cases to note about ``list_display``:
If the field is a `` Foreign Key ? ``, Django will display the
`` unicode ()`` of the related object.
`` Many To Many Field ? `` fields aren’t supported, because that would entail
executing a separate SQL statement for each row in the table. If you
want to do this nonetheless, give your model a custom method, and add
that method’s name to ``list_display``. (See below for more on custom
methods in ``list_display``.)
If the field is a `` Boolean Field ? `` or `` Null Boolean Field ? ``, Django will
display a pretty “on” or “off” icon instead of ``True`` or ``False``.
If the string given is a method of the model, Django will call it and
display the output. This method should have a ``short_description``
function attribute, for use as the header for the field.
Here’s a full example model::
class Person(models.Model):
name = models.CharField(max_length=50)
birthday = models.DateField()
def decade_born_in(self):
return self.birthday.strftime('%Y')[:3] + "0's"
decade_born_in.short_description = 'Birth decade'
class PersonAdmin(admin.ModelAdmin):
list_display = ('name', 'decade_born_in')
If the string given is a method of the model, Django will HTML -escape the
output by default. If you’d rather not escape the output of the method,
give the method an ``allow_tags`` attribute whose value is ``True``.
Here’s a full example model::
class Person(models.Model):
first_name = models.CharField(max_length=50)
last_name = models.CharField(max_length=50)
color_code = models.CharField(max_length=6)
def colored_name(self):
return ' %s %s ' (self.color_code, self.first_name, self.last_name)
colored_name.allow_tags = True
class PersonAdmin(admin.ModelAdmin):
list_display = ('first_name', 'last_name', 'colored_name')
If the string given is a method of the model that returns True or False
Django will display a pretty “on” or “off” icon if you give the method a
``boolean`` attribute whose value is ``True``.
Here’s a full example model::
class Person(models.Model):
first_name = models.CharField(max_length=50)
birthday = models.DateField()
def born_in_fifties(self):
return self.birthday.strftime('%Y')[:3] == 5
born_in_fifties.boolean = True
class PersonAdmin(admin.ModelAdmin):
list_display = ('name', 'born_in_fifties')
Usually, elements of ``list_display`` that aren’t actual database fields
can’t be used in sorting (because Django does all the sorting at the
database level).
However, if an element of ``list_display`` represents a certain database
field, you can indicate this fact by setting the ``admin_order_field``
attribute of the item.
For example::
class Person(models.Model):
first_name = models.CharField(max_length=50)
color_code = models.CharField(max_length=6)
def colored_first_name(self):
return ' %s ' (self.color_code, self.first_name)
colored_first_name.allow_tags = True
colored_first_name.admin_order_field = 'first_name'
class PersonAdmin(admin.ModelAdmin):
list_display = ('first_name', 'colored_first_name')
The above will tell Django to order by the ``first_name`` field when
trying to sort by ``colored_first_name`` in the admin.
``list_display_links`` ~ ~ ~ ~ ~ ~ ~
Set ``list_display_links`` to control which fields in ``list_display`` should be linked to the “change” page for an object.
By default, the change list page will link the first column—the first field specified in ``list_display``—to the change page for each item. But ``list_display_links`` lets you change which columns are linked. Set ``list_display_links`` to a list or tuple of field names (in the same format as ``list_display``) to link.
``list_display_links`` can specify one or many field names. As long as the field names appear in ``list_display``, Django doesn’t care how many (or how few) fields are linked. The only requirement is: If you want to use ``list_display_links``, you must define ``list_display``.
In this example, the ``first_name`` and ``last_name`` fields will be linked on the change list page::
class PersonAdmin(admin.ModelAdmin):
list_display = ('first_name', 'last_name', 'birthday')
list_display_links = ('first_name', 'last_name')
Finally, note that in order to use ``list_display_links``, you must define ``list_display``, too.
``list_filter`` ~ ~ ~ ~ ~
Set ``list_filter`` to activate filters in the right sidebar of the change list page of the admin. This should be a list of field names, and each specified field should be either a `` Boolean Field ? ``, `` Char Field ? ``, `` Date Field ? ``, `` Date Time Field ? ``, `` Integer Field ? `` or `` Foreign Key ? ``.
This isexample, ataken test…from the ``django.contrib.auth.models.User`` model, shows how both ``list_display`` and ``list_filter`` work::

blablaThe above code results in an admin change list page that looks like this:
.. image:: http://media.djangoproject.com/img/doc/users_changelist.png
(This example also has ``search_fields`` defined. See below.)
————-—————``list_per_page`` ~ ~ ~ ~ ~ ~
ThisSet ``list_per_page`` to control how many items appear on each paginated admin change list page. By default, this is anotherset testto here``100``.
``list_select_related`` ~ ~ ~ ~ ~ ~ ~
Please,Set do``list_select_related`` notto edittell anyDjango pagesto use ``select_related()`` in retrieving the list of objects on the mainadmin Wikichange forlist thepage. sakeThis can save you a bunch of tryingdatabase itqueries.
The out.value Useshould be either ``True`` or ``False``. Default is ``False``.
Note that Django will use ``select_related()``, regardless of this setting, if one of the sandbox``list_display`` linksfields above.is a `` Foreign Key ? ``.
For more on ``select_related()``, see `the select_related() docs`_.
.. _the select_related() docs: ../db-api/#select-related
``inlines`` ~ ~ ~
See `` Inline Model Admin ? `` objects below.
``ordering`` ~ ~ ~ ~
Set ``ordering`` to specify how objects on the admin change list page should be ordered. This should be a list or tuple in the same format as a model’s ``ordering`` parameter.
If this isn’t provided, the Django admin will use the model’s default ordering.
``prepopulated_fields`` ~ ~ ~ ~ ~ ~ ~
Set ``prepopulated_fields`` to a dictionary mapping field names to the fields it should prepopulate from::
taskclass :search_libs,ArticleAdmin(admin.ModelAdmin):
prepopulated_fields :hosts= =>{"slug": "www.capify.org"("title",)}
When set the given fields will use a bit of Javascript to populate from the fields assigned.
``prepopulated_fields`` doesn’t accept Date Time Fields ? , Foreign Keys ? nor Many To Many Fields ? .
``radio_fields`` ~ ~ ~ ~ ~
By default, Django’s admin uses a select-box interface ( ) for fields that are `` Foreign Key ? `` or have ``choices`` set. If a field is present in ``radio_fields``, Django will use a radio-button interface instead. Assuming ``group`` is a `` Foreign Key ? `` on the ``Person`` model::
class PersonAdmin(admin.ModelAdmin):
radio_fields = {"group": admin.VERTICAL}
You have the choice of using ``HORIZONTAL`` or ``VERTICAL`` from the ``django.contrib.admin`` module.
Don’t include a field in ``radio_fields`` unless it’s a `` Foreign Key ? `` or has ``choices`` set.
``raw_id_fields`` ~ ~ ~ ~ ~ ~
By default, Django’s admin uses a select-box interface ( ) for fields that are `` Foreign Key ? ``. Sometimes you don’t want to incur the overhead of having to select all the related instances to display in the drop-down.
``raw_id_fields`` is a list of fields you would like to change into a ``Input`` widget for the primary key.
``save_as`` ~ ~ ~
Set ``save_as`` to enable a “save as” feature on admin change forms.
Normally, objects have three save options: “Save”, “Save and continue editing” and “Save and add another”. If ``save_as`` is ``True``, “Save and add another” will be replaced by a “Save as” button.
“Save as” means the object will be saved as a new object (with a new ID), rather than the old object.
By default, ``save_as`` is set to ``False``.
``save_on_top`` ~ ~ ~ ~ ~
Set ``save_on_top`` to add save buttons across the top of your admin change forms.
Normally, the save buttons appear only at the bottom of the forms. If you set ``save_on_top``, the buttons will appear both on the top and the bottom.
By default, ``save_on_top`` is set to ``False``.
``search_fields`` ~ ~ ~ ~ ~
Set ``search_fields`` to enable a search box on the admin change list page. This should be set to a list of field names that will be searched whenever somebody submits a search query in that text box.
These fields should be some kind of text field, such as `` Char Field ? `` or `` Text Field ? ``. You can also perform a related lookup on a `` Foreign Key ? `` with the lookup API “follow” notation::
search_fields = ['foreign_key__related_fieldname']
When somebody does a search in the admin search box, Django splits the search query into words and returns all objects that contain each of the words, case insensitive, where each word must be in at least one of ``search_fields``. For example, if ``search_fields`` is set to ``[‘first_name’, ‘last_name’]`` and a user searches for ``john lennon``, Django will do
run "lsthe -x1equivalent /usr/libof |this grepSQL ``WHERE`` -iclause::
WHERE xml"
end(first_name ILIKE ' john ' OR last_name ILIKE ' john ')
AND (first_name ILIKE ' lennon ' OR last_name ILIKE ' lennon ')
For faster and/or more restrictive searches, prefix the field name with an operator:
`` ``
Matches the beginning of the field. For example, if ``search_fields`` is
set to ``[’ first_name’, ’ last_name’]`` and a user searches for
``john lennon``, Django will do the equivalent of this SQL ``WHERE``
clause::
WHERE (first_name ILIKE 'john%' OR last_name ILIKE 'john%')
AND (first_name ILIKE 'lennon%' OR last_name ILIKE 'lennon%')
This query is more efficient than the normal ``' john '`` query, because
the database only needs to check the beginning of a column's data, rather
than seeking through the entire column's data. Plus, if the column has an
index on it, some databases may be able to use the index for this query,
even though it's a ``LIKE`` query.
``=``
Matches exactly, case-insensitive. For example, if
``search_fields`` is set to ``[’=first_name’, ’=last_name’]`` and
a user searches for ``john lennon``, Django will do the equivalent
of this SQL ``WHERE`` clause::
WHERE (first_name ILIKE 'john' OR last_name ILIKE 'john')
AND (first_name ILIKE 'lennon' OR last_name ILIKE 'lennon')
Note that the query input is split by spaces, so, following this example,
it's currently not possible to search for all records in which
``first_name`` is exactly ``'john winston'`` (containing a space).
``@``
Performs a full-text match. This is like the default search method but uses
an index. Currently this is only available for My SQL .
`` fileModel Admin ? `` media definitions ————————————————
There are times where you would like add a bit of CSS and/or Javascript to the add/change views. This can be accomplished by using a Media inner class on your `` Model Admin ? ``::
class ArticleAdmin(admin.ModelAdmin):
class Media:
css = {
"all": ("my_styles.css",)
}
js = ("my_code.js",)
Keep in mind that this will be prepended with ``MEDIA_URL``. The same rules apply as `regular media definitions on forms`_.
.. _regular media definitions on forms: ../newforms/#media
`` Inline Model Admin ? `` objects ============================
The admin interface has the ability to edit models on the same page as a parent model. These are called inlines. You can add them a model being specifing them in a `` Model Admin ? .inlines`` attribute::
class BookInline(admin.TabularInline):
model = Book
class AuthorAdmin(admin.ModelAdmin):
inlines = [
BookInline,
]
Django provides two subclasses of `` Inline Model Admin ? `` and they are::
`` Tabular Inline ? ``
`` Stacked Inline ? ``
The difference between these two is merely the template used to render them.
`` Inline Model Admin ? `` options ——————————————-
The `` Inline Model Admin ? `` class is a subclass of `` Model Admin ? `` so it inherits all the same functionality as well as some of its own:
``model`` ~ ~ ~
The model in which the inline is using. This is required.
``fk_name`` ~ ~ ~
The name here.jpgof the foreign key on the model. In most cases this will be dealt with automatically, but ``fk_name`` must be specified explicitly if there are more than one foreign key to the same parent model.
``formset`` ~ ~ ~
This defaults to `` Base Inline Formset ? ``. Using your own formset can give you many possibilities of customization. Inlines are built around `model formsets`_.
hello!!!.. _model formsets: ../modelforms/#model-formsets
some/page``form`` another page~ ~
tryingThe value for ``form`` is inherited from `` Model Admin ? ``. This is what is passed through to see``formset_factory`` when creating the formset for this inline.
``extra`` ~ ~ ~
This controls the number of extra forms the formset will display in addition to the initial forms. See the `formsets documentation`_ for more information.
.. _formsets documentation: ../newforms/#formsets
``max_num`` ~ ~ ~
This controls the maximum number of forms to show in the inline. This doesn’t directly corrolate to the number of objects, but can if ithe canvalue getis asmall enough. titleSee `max_num in formsets`_ for more information.
.. _max_num in formsets: ../modelforms/#limiting-the-number-of-objects-editable
``template`` ~ ~ ~ ~
The template used to render the inline on the page.
``verbose_name`` ~ ~ ~ ~ ~
An override to the ``verbose_name`` found in the model’s inner ``Meta`` class.
``verbose_name_plural`` ~ ~ ~ ~ ~ ~ ~ ~~
An override to the ``verbose_name_plural`` found in the model’s inner ``Meta`` class.
Working with a colonmodel with two or more foreign keys to the same parent model —————————————————————————————————————-
It is sometimes possible to have more than one foreign key to the same model. Take this model for ainstance::
class pageFriendship(models.Model):
to_person = models.ForeignKey(Person, related_name="friends")
from_person = models.ForeignKey(Person, related_name="from_friends")
If you wanted to display an inline on the ``Person`` admin add/change pages you need to explicitly define the foreign key since it is unable to do so automatically::
class FriendshipInline(admin.TabularInline):
model = Friendship
fk_name = "to_person"
class PersonAdmin(admin.ModelAdmin):
inlines = [
FriendshipInline,
]
`` Admin Site ? `` objects =====================
LordHooking `` Admin Site ? `` instances into your URLconf ————————————————————————-
The last step in setting up the Django admin is to hook your `` Admin Site ? `` instance into your URLconf. Do this by pointing a given URL at the `` Admin Site ? .root`` method.
In this example, we register the default `` Admin Site ? `` instance ``django.contrib.admin.site`` at the URL ``/admin/`` ::
urls.py
from django.conf.urls.defaults import
from django.contrib import admin
admin.autodiscover()
urlpatterns = patterns('',
(' admin/(. )', admin.site.root),
)
Above we used ``admin.autodiscover()`` to automatically load the ``INSTALLED_APPS`` admin.py modules.
In this example, we register the `` Admin Site ? `` instance ``myproject.admin.admin_site`` at the URL ``/myadmin/`` ::
urls.py
from django.conf.urls.defaults import
from myproject.admin import admin_site
urlpatterns = patterns('',
(' myadmin/(. )', admin_site.root),
)
There is really no need to use autodiscover when using your own `` Admin Site ? `` instance since you will likely be importing all the per-app admin.py modules in your ``myproject.admin`` module.
Note that the regular expression in the URLpattern must group everything in the URL that comes after the URL root—hence the ``(. )`` in these examples.
Multiple admin sites in the same URLconf ————————————————————
It’s easy to create multiple instances of the Rings:admin Thesite Twoon Towersthe same Django-powered Web site. Just create multiple instances of `` Admin Site ? `` and root each one at a different URL .
