Django mixin to easily add urls to any ModelAdmin

Project description

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.

Install

pip install admin-extra-urls

After installation add it to INSTALLED_APPS

INSTALLED_APPS = (
    ...
    'admin_extra_urls',
)

How to use it

from admin_extra_urls.extras import ExtraUrlMixin, link, action

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):
        obj = self.get_object(pk=pk)
        ...

You don’t need to return a HttpResponse. The default behavior is:

  • with link() button is displayed in the ‘list’ view and the browser will be redirected to changelist_view
  • with action() button is displayed in the ‘update’ view and the browser will be redirected to change_view

Integration with other libraries

django-import-export

@admin.register(Rule)
class RuleAdmin(ExtraUrlMixin, ImportExportMixin, BaseModelAdmin):
    @link(label='Export')
    def _export(self, request):
        return self.export_action(request)

    @link(label='Import')
    def _import(self, request):
        return self.import_action(request)
