Django Admin Steroids - Tweaks and tools to extend Django admin
===============================================================
[](https://pypi.python.org/pypi/django-admin-steroids)
[](https://gitlab.com/chrisspen/django-admin-steroids/commits/master)
Overview
--------
Django's admin supports a lot of customization. However, the current
implementation relies on the use of class values and methods, requiring a lot
of code duplication. This project contains classes, mixins, and a few templates
that improve the usability and maintainability of Django's admin, and implement
some missing features.
Features
--------
**ModelAdmin mixins:**
- ReadonlyModelAdmin - Removes all editability from the ModelAdmin.
- CSVModelAdmin - Adds a changelist action to export the selected records as a CSV.
- FormatterModelAdmin - Allows the use of admin field formatters.
- BetterRawIdFieldsModelAdmin - Adapted from a `Django Snippet
<http://djangosnippets.org/snippets/2217/>`_,
this formats all raw id fields with a convenient link to that record's
corresponding admin change page.
**Field formatters:**
If you want to format a monetary dollar value with a dollar sign
and commas, you have to implement a myvariable_dollars() method in your
ModelAdmin class that returns the desired string, and then list this method
in the ModelAdmin's readonly_fields list.
In many non-trivial applications, I found myself writing a huge number of these
functions, most of which were nearly identical. So I decided to abstract this
functionality into a number of classes that could be instantiated and easily
plugged into a ModelAdmin.
Pre-built formatters include:
- DollarFormat
- PercentFormat
- CenterFormat
- NbspFormat
- BooleanFormat
- ForeignKeyLink
- OneToManyLink
Formatters are used by wrapping them around field names in a ModelAdmin.
Say you have a model with a field called `income` that you want to display in
admin formatted with a dollar sign. Normally, you'd do something like this:
class BudgetAdmin(admin.ModelAdmin):
fields = (
'id',
'name',
'income_str',
)
readonly_fields = (
'income_str',
)
def income_str(self, request, obj=None):
if obj is None:
return
return '$%.2f' % obj.income
Formatters simply this process. In this example, you could use the DollarFormat
class to accomplish the same thing with much less code:
from admin_steroids import FormatterModelAdmin
from admin_steroids.formatters import DollarFormat
class BudgetAdmin(FormatterModelAdmin):
fields = (
'id',
'name',
DollarFormat('income', decimals=2),
)
**Ajax list filters:**
Django's default admin list filters don't allow selecting multiple values
for a field, nor do they handle fields with large numbers of values.
Fields render **all** values in a list or select drop-down, slowing down page
load and wasting screen space.
I've implemented a custom AjaxFieldFilter which allows you to search for one
or more values via an Ajax-powered search bar, so admin still renders quickly
while the user is still able to search for any value used by the field.
In your admin, add the AjaxFieldFilter like:
from django.contrib import admin
from admin_steroids.filters import AjaxFieldFilter
import models
class MyModelAdmin(admin.ModelAdmin):
list_filters = (
('myfield', AjaxFieldFilter),
)
admin.site.register(models.MyModel, MyModelAdmin)
Then, in your settings.py, add 'admin_steroids' to your `INSTALLED_APPS`, and flag your field as safe to search:
INSTALLED_APPS = [
...,
'admin_steroids',
]
DAS_ALLOWED_AJAX_SEARCH_PATHS = [
('myapp', 'mymodel', 'myfield'),
]
DAS_AJAX_SEARCH_PATH_FIELDS = {
# This assumed "myfield" a ForeignKey, pointing to a model that has
# a "name" and "slug" field you want to search.
# If "myfield" is a simple CharField, you don't need to specify
# anything here.
('myapp', 'mymodel', 'myfield'): ('name', 'slug'),
}
Finally, add admin_steroids to your urls.py to expose the Ajax search URLs,
which by default will be rendered in the form `/admin/<app>/<model>/field/<field>/search`:
urlpatterns = patterns('',
...
# Should go before the actual admin, so it won't be overridden.
(r'^admin/', include('admin_steroids.urls')),
(r'^admin/', include(admin.site.urls)),
...
)
You can override these URLs by excluding the URL include above and specifying
your own pattern pointing to admin_steroids.views.ModelFieldSearchView.
See admin_steroids.urls for an example.
Installation
------------
Install the package via pip with:
pip install django-admin-steroids
Development
-----------
Tests require the Python development headers to be installed, which you can install on Ubuntu
using the [Dead Snakes PPA](https://launchpad.net/~fkrull/+archive/ubuntu/deadsnakes) with:
sudo apt-get install python-dev python3-dev python3.4-minimal python3.4-dev python3.5-minimal python3.5-dev python3.6-minimal python3.6-dev
To run all [tests](http://tox.readthedocs.org/en/latest/):
export TESTNAME=; tox
To run tests for a specific environment (e.g. Python 3.7 with Django 3.2):
export TESTNAME=; tox -e py37-django32
To run a specific test:
export TESTNAME=.test_widgets; tox -e py37-django32
