App Hooks, what's the thing?

is a means of integrating existing apps into a CMS.

There are two ways to achieve this:

1) define the cms_app.py as follows:

From cms.app_base import cmsappfrom cms.apphook_pool import apphook_poolfrom django.utils.translation import Ugettext_ Lazy as _class Myapphook (cmsapp):    name = _ ("My apphook")    urls = ["Myapp.urls"]apphook_pool.register (Myapphook)

Official documents See here: Http://docs.django-cms.org/en/latest/extending_cms/app_integration.html#app-hooks

Load logic, loaded via Discover_apps's Load (' Cms_app ') (if cms_apphooks is not defined in settings.py): In all Installed_app, find the Cms_app module, and automatically Import_module

2) define Cms_apphooks in setting.py

apphooks= (' Yourmodule.you_object1 ', ' Yourmodule.you_object2 ',...)

This is from the source code analysis, the following:

C:\Python27\Lib\site-packages\django_cms-3.0.3-py2.7.egg\cms\apphook_pool.py (45~57)

    def discover_apps (self):        self.apphooks = get_cms_setting (' apphooks ')        if self.apphooks: for            CLS in Iterload_objects (self.apphooks):                try:                    self.register (CLS, discovering_apps=true)                except appalreadyregistered:                    Pass        else:            load (' Cms_app ')        self.discovered = True

Iterload_objects, is a generator, as follows:

def iterload_objects (import_paths): "" "    Load a list of objects.    " " For Import_path in import_paths:        yield load_object (import_path)

Load_object

def load_object (Import_path):    if '. ' Not in Import_path:        raise TypeError (            "' import_path ' argument to ' Django_load.core.load_object ' must "            " contain at least one dot. "        )    Module_name, object_name = Import_path.rsplit ('. ', 1)    module = import_module (module_name)    return GetAttr ( module, object_name)
