Django Admin Steroids - Tweaks and tools to extend Django admin =============================================================== [![](https://img.shields.io/pypi/v/django-admin-steroids.svg)](https://pypi.python.org/pypi/django-admin-steroids) [![Pipeline Status](https://gitlab.com/chrisspen/django-admin-steroids/badges/master/pipeline.svg)](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
