Django mixin to easily add urls to any ModelAdmin
pluggable django application that offers one single mixin class ExtraUrlMixin to easily add new url (and related buttons on the screen) to any ModelAdmin.
It provides two decorators link() and action().
link() is intended to be used for multiple records. It will produce a button in the change list view.
action() works on a single record. It will produce a button in the change form view.
pip install admin-extra-urls
After installation add it to INSTALLED_APPS
INSTALLED_APPS = ( ... 'admin_extra_urls', )
How to use it
class MyModelModelAdmin(ExtraUrlMixin, admin.ModelAdmin): @link() # /admin/myapp/mymodel/update_all/ def update_all(self, request): ... ... @action() # /admin/myapp/mymodel/update/10/ def update(self, request, pk): ... ...
You don’t need to return a HttpResponse. The default behavior is:
with link() browser will be redirected to changelist_view
with action() browser will be redirected to change_view
link() / action() options
path url path for the action. will be the url where the button will point to.
label for the button. by default the “labelized” function name

permission required to use the button. can be a callable qith the current object as argument.
extra css classes to use for the button
in case of multiple button the order to use

callable or bool. By default do not display the button if in add mode
