django-admin-additions Description

django-admin-additions is a Django app that provides admin additions. Here are solutions to those, all bundled up together.InstallationAdd 'admin_additions' to you settings.INSTALLED_APPS.Then configure the additions you want to use. The default settings are shown:ADMIN_ADDITIONS = { 'RETURN_TO_FILTERED_CHANGELIST': False, 'SAVE_ON_TOP': True, 'LIST_SELECT_RELATED': False, 'FULLY_DYNAMIC_FORMSETS': True}SettingsRETURN_TO_FILTERED_CHANGELISTWhen editing an object, you usually want to revert back to the filtered view from whence you came.This is a monkey-patch that supplements the normal change_view method on the ModelAdmin base class, and ensures that it returns after a POST back to the referring view.This method of returning to the filtered view after submitting a form in an admin change view is based largely upon Snippet 2531 http://djangosnippets.org/snippets/2531/.SAVE_ON_TOPShould be the default: display the save toolbar on the top of every change_view.LIST_SELECT_RELATEDTurn on automatic .select_related() for all queries for a change_list. If you have altered the display columns, and do any lookups at all, this is a good idea.FULLY_DYNAMIC_FORMSETSSets the extra value on InlineModelAdmin to 0, so you just use the addition button instead of having any empty formsets.Patching functionspatch_model_admin(model, patch_function)Patch an installed ModelAdmin. This includes unregistering, patching and then re-registering. You may pass in a model, or a string of the form "app_label.ModelName", and a function that will take and patch a ModelAdmin class.If you create a new class based on the passed in class, then you may return it: that will then be used within the re-registration. If you simply patch the existing class, you can return nothing, and the patched original class will be used.from admin_additions.patchers import patch_model_admindef patcher_function(model_admin): # Do stuff here. model_admin.form = MyClassyForm return model_admin # optional: you may patch in-placepatch_model_admin(MyModel, patcher_function)add_inlines(model, *inlines)A simple/common case of patching a ModelAdmin - adding a new inline:from django.contrib import adminfrom admin_additions.patchers import add_inlinesfrom models import Fooclass FooInline(admin.StackedInline): model = Fooadd_inlines('bar.Bar', FooInline)You may pass multiple inlines.You may also pass in any combination of models or admin inlines: if a model is received, it will create a StackedInline for that model.add_actions(model, *actions)Like for inlines, but add an action.@patch_admin(model)A decorator, that can decorate a function to be patched.from admin_additions.patchers import patch_admin@patch_admin(model)def patcher_function(model_admin): model_admin.form = MyClassyFormThis syntax is terser than the patch_model_admin function above.Product's homepage
