Namespaces based configuration for Apphooks
The concept of apphooks-config is to store all the configuration in an applications-specific model, and let the developer specify the desired option in a form. In the views the model instance specific for the current application namespace is loaded (through a mixin) and it's thus available in the view to provide the configuration for the current namespace.
Namespaces can be created on the fly in the Page
admin
Advanced settings by following the steps above.
When creating an application configuration, you are in fact defining a
namespace, which is saved in the same field in the Page
model as the
plain namespaces.

Define a AppHookConfig model in
cms_appconfig.py
:from aldryn_apphooks_config.models import AppHookConfig class NewsBlogConfig(AppHookConfig): pass
Implementation can be completely empty as the schema is defined in the parent (abstract) model
Use apphooks managers in your model:
from aldryn_apphooks_config.managers import AppHookConfigManager class Article(models.Model): title = models.CharField() objects = AppHookConfigManager()
AppHookConfigManager
adds namespace
method to manager and queryset:
Article.objects.namespace('foobar')
There is also a proper queryset, the ApphooksConfigQueryset
. Parler
integrated variants can be found in aldryn_apphooks_config.managers.parler
.
Names are AppHookConfigTranslatableManager
and
AppHookConfigTranslatableQueryset
.
Define a ConfigForm in
cms_appconfig.py
:from app_data import AppDataForm from django import forms from aldryn_newsblog.models import NewsBlogConfig from aldryn_apphooks_config.utils import setup_config class BlogOptionForm(AppDataForm): # fields are totally arbitrary: any form field supported by # django-appdata is supported show_authors = forms.BooleanField(required=False) ... # this function will register the provided form with the model created # at the above step setup_config(BlogOptionForm, NewsBlogConfig) # setup_config can be used as a decorator too, but the `model` # attribute must be added to the form class @setup_config class BlogOptionForm(AppDataForm): model = NewsBlogConfig
Define an admin class for the AppHookConfig model (usually in
admin.py
:from django.contrib import admin from aldryn_apphooks_config.admin import BaseAppHookConfig class BlogConfigAdmin(BaseAppHookConfig): def get_config_fields(self): # this method **must** be implemented and **must** return the # fields defined in the above form, with the ``config`` prefix # This is dependent on the django-appdata API return ('config.show_authors', ...)
Define a CMSApp derived from CMSConfigApp provided by this application (in
cms_app.py
/cms_apps.py
):from aldryn_apphooks_config.app_base import CMSConfigApp from cms.apphook_pool import apphook_pool from django.utils.translation import ugettext_lazy as _ from .models import NewsBlogConfig class NewsBlogApp(CMSConfigApp): name = _('NewsBlogApp') urls = ['aldryn_newsblog.urls'] app_name = 'aldryn_newsblog' # this option is specific of CMSConfigApp, and links the # CMSApp to a specific AppHookConfig model app_config = NewsBlogConfig apphook_pool.register(NewsBlogApp)
Implements your views inheriting the
AppConfigMixin
:from django.views.generic.detail import DetailView from aldryn_apphooks_config.mixins import AppConfigMixin class ArticleDetail(AppConfigMixin, DetailView): def get_queryset(self): return Article.objects.namespace(self.namespace)
AppConfigMixin
provides a complete support to namespaces, so the view is not required to set anything specific to support them; the following attributes are set for the view class instance:- current namespace in
self.namespace
- namespace configuration (the instance of NewsBlogConfig) in
self.config
- current application in the
current_app
parameter passed to the Response class
- current namespace in
To properly setup the data for tests to run for a apphook-config enabled application, make sure you add the following code to your TestCase:
MyTestCase(): def setUp(self): # This is the namespace represented by the AppHookConfig model instance self.ns_newsblog = NewsBlogConfig.objects.create(namespace='NBNS') self.page = api.create_page( 'page', self.template, self.language, published=True, # this is the name of the apphook defined in the CMSApp class apphook='NewsBlogApp', # The namespace is the namespace field of the AppHookConfig instance created above apphook_namespace=self.ns_newsblog.namespace) # publish the page to make the apphook available self.page.publish(self.language)
