``autocomplete_fields`` is a list of ``ForeignKey`` and/or
|
||||
``ManyToManyField`` fields you would like to change to `Select2
|
||||
<https://select2.org/>`_ autocomplete inputs.
|
||||
|
||||
By default, the admin uses a select-box interface (``<select>``) for fields
|
||||
that are . Sometimes you don't want to incur the overhead of selecting all
|
||||
the related instances to display in the dropdown.
|
||||
|
||||
The Select2 input looks similar to the default input but comes with a
|
||||
search feature that loads the options asynchronously. This is faster and
|
||||
more user-friendly if the related model has many instances.
|
||||
|
||||
You must define :attr:`~ModelAdmin.search_fields` on the related object's
|
||||
``ModelAdmin`` because the autocomplete search uses it.
|
||||
|
||||
Ordering and pagination of the results are controlled by the related
|
||||
``ModelAdmin``'s :meth:`~ModelAdmin.get_ordering` and
|
||||
:meth:`~ModelAdmin.get_paginator` methods.
|
||||
|
||||
In the following example, ``ChoiceAdmin`` has an autocomplete field for the
|
||||
``ForeignKey`` to the ``Question``. The results are filtered by the
|
||||
``question_text`` field and ordered by the ``date_created`` field::
|
||||
|
||||
class QuestionAdmin(admin.ModelAdmin):

|
||||
|
||||
.. admonition:: Performance considerations for large datasets
|
||||
|
||||
Ordering using :attr:`ModelAdmin.ordering` may cause performance
|
||||
problems as sorting on a large queryset will be slow.
|
||||
|
||||
Also, if your search fields include fields that aren't indexed by the
|
||||
database, you might encounter poor performance on extremely large
|
||||
tables.
|
||||
|
||||
For those cases, it's a good idea to write your own
|
||||
:func:`ModelAdmin.get_search_results` implementation using a
|
||||
full-text indexed search.
|
||||
|
||||
You may also want to change the ``Paginator`` on very large tables
|
||||
as the default paginator always performs a ``count()`` query.
|
||||
For example, you could override the default implementation of the
|
||||
``Paginator.count`` property.
