django CMS blog application - Support for multilingual posts, placeholders, social network meta tags and configurable apphooks.

Supported Django versions:

* Django 1.6
* Django 1.7
* Django 1.8
* Django 1.9

Supported django CMS versions:

* django CMS 3.x

.. warning:: Version 0.8 will be the last one supporting Python 2.6, Python 3.3,
             Django<1.8 and django CMS<3.2.

.. warning:: Starting from version 0.8, date_published is not set anymore
             when creating a post but rather when publishing.
             This does not change the overall behavior, but be warned if you
             expect it to be not null in custom code.

.. warning:: Version 0.6 changes the field of LatestPostsPlugin.tags field.
             A datamigration is in place to migrate the data, but check that
             works ok for your project before upgrading, as this might delete
             some relevant data.
             Some plugins have a broken tag management prior to 0.6, in case
             you have issues with tags, upgrade to latest version to have it fixed.

Upgrading cmsplugin-filer from 1.0 to 1.1
-----------------------------------------

Due to changes in cmsplugin-filer/filer which moved ``ThumbnailOption`` model from the
former to the latter, ``djangocms-blog`` must be migrated as well.

Migrating cmsplugin-filer to 1.1 and djangocms-blog up to 0.8.4
+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

If you have djangocms-blog up to 0.8.4 (included) installed or you are upgrading from a previous
djangocms-blog version together with cmsplugin-filer upgrade, you can just apply the migrations::

    pip install cmsplugin-filer==1.1.1 django-filer==1.2.2 djangocms-blog==0.8.4
    python manage.py migrate

Migrating cmsplugin-filer to 1.1 and djangocms-blog 0.8.5+
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

If you already a djangocms-blog 0.8.5+ or above, you have to de-apply some blog migrations when
doing the upgrade::

    python manage.py migrate djangocms_blog 0017 ## reverse for these migration is a noop
    pip install cmsplugin-filer==1.1.1 django-filer==1.2.2
    python manage.py migrate

.. note:: de-apply migration **before** upgrading cmsplugin-filer. If running before upgrade, the
          backward migration won't alter anything on the database, and it will just allow the code
          to migrate ``ThumbnailOption`` from cmsplugin-filer to filer

Add ``djangocms_blog`` and its dependencies to INSTALLED_APPS::

    INSTALLED_APPS = [
        ...
        'filer',
        'easy_thumbnails',
        'aldryn_apphooks_config',

        ...
    ]

If you installed the **admin-enhancer** variant, add ``admin_enhancer`` to ``INSTALLED_APPS``::

    INSTALLED_APPS = [
        ...
        'admin_enhancer',
        ...
    ]


Then sync and migrate::

    $ python manage.py syncdb
    $ python manage.py migrate

External applications configuration
+++++++++++++++++++++++++++++++++++

Dependency applications may need configuration to work properly.

Please, refer to each application documentation on details.

* django-filer: http://django-filer.readthedocs.org
* django-meta: https://github.com/nephila/django-meta#installation
* django-meta-mixin: https://github.com/nephila/django-meta-mixin#installation
* django-parler: http://django-parler.readthedocs.org/en/latest/quickstart.html#configuration
* django-taggit-autosuggest: https://bitbucket.org/fabian/django-taggit-autosuggest

Quick hint
++++++++++

The following are minimal defaults to get the blog running; they may not be
suited for your deployment.

* Add the following settings to your project::

    SOUTH_MIGRATION_MODULES = {
        'easy_thumbnails': 'easy_thumbnails.south_migrations',
        'taggit': 'taggit.south_migrations',
    }
    THUMBNAIL_PROCESSORS = (
        'easy_thumbnails.processors.colorspace',
        'easy_thumbnails.processors.autocrop',
        'filer.thumbnail_processors.scale_and_crop_with_subject_location',
        'easy_thumbnails.processors.filters',
    )
    META_SITE_PROTOCOL = 'http'
    META_USE_SITES = True

* If you are using Django 1.7+, be aware that ``filer`` < 0.9.10,
  ``cmsplugin_filer`` and ``django-cms`` < 3.1 currently requires you to
  setup ``MIGRATION_MODULES`` in settings::

    MIGRATION_MODULES = {
       'cms': 'cms.migrations_django', # only for django CMS 3.0
       'menus': 'menus.migrations_django',  # only for django CMS 3.0
       'filer': 'filer.migrations_django',  # only for django filer up to 0.9.9
       'cmsplugin_filer_image': 'cmsplugin_filer_image.migrations_django',
    }

  Please check
  `django CMS installation <http://django-cms.readthedocs.org/en/support-3.0.x/how_to/integrate.html#installing-and-configuring-django-cms-in-your-django-project>`_,
  `cmsplugin-filer README <https://github.com/stefanfoulis/cmsplugin-filer#installation>`_
  for detailed information.

* Configure parler according to your languages::

    PARLER_LANGUAGES = {
        1: (
            {'code': 'en',},
            {'code': 'it',},
            {'code': 'fr',},
        ),
        'default': {
            'fallbacks': ['en', 'it', 'fr'],
        }
    }

* Add the following to your ``urls.py``::

    url(r'^taggit_autosuggest/', include('taggit_autosuggest.urls')),

* To start your blog you need to use `AppHooks from django CMS <http://django-cms.readthedocs.org/en/support-3.0.x/how_to/apphooks.html>`_
  to add the blog to a django CMS page; this step is not required when using
  `Auto setup <auto_setup>`_:

  * Create a new django CMS page
  * Go to **Advanced settings** and select Blog from the **Application** selector and
    create an **Application configuration**;
  * Eventually customise the Application instance name;
  * Publish the page
  * Restart the project instance to properly load blog urls.

.. warning:: After adding the apphook to the page you **cannot** change the **Instance Namspace**
             field for the defined **AppHokConfig**; if you want to change it, create a new one
             with the correct namespace, go in the CMS page **Advanced settings** and switch to the
             new **Application configuration**

* Add and edit blog by creating them in the admin or using the toolbar,
  and the use the `django CMS frontend editor <http://django-cms.readthedocs.org/en/support-3.0.x/user/reference/page_admin.html#the-interface>`_
  to edit the blog content:

  * Create a new blog entry in django admin backend or from the toolbar
  * Click on "view on site" button to view the post detail page
  * Edit the post via djangocms frontend by adding / editing plugins
  * Publish the blog post by flagging the "Publish" switch in the blog post
    admin

Configurable permalinks
+++++++++++++++++++++++

Blog comes with four different styles of permalinks styles:

* Full date: ``YYYY/MM/DD/SLUG``
* Year /  Month: ``YYYY/MM/SLUG``
* Category: ``CATEGORY/SLUG``
* Just slug: ``SLUG``

As all the styles are loaded in the urlconf, the latter two does not allow
to have CMS pages beneath the page the blog is attached to. If you want to
do this, you have to override the default urlconfs by setting something
like the following in the project settings::

    BLOG_PERMALINK_URLS = {
        'full_date': r'^(?P<year>\d{4})/(?P<month>\d{1,2})/(?P<day>\d{1,2})/(?P<slug>\w[-\w]*)/$',
        'short_date': r'^(?P<year>\d{4})/(?P<month>\d{1,2})/(?P<slug>\w[-\w]*)/$',
        'category': r'^post/(?P<category>\w[-\w]*)/(?P<slug>\w[-\w]*)/$',
        'slug': r'^post/(?P<slug>\w[-\w]*)/$',
    }

And change ``post/`` with the desired prefix.

Attaching blog to the home page
+++++++++++++++++++++++++++++++

If you want to attach the blog to the home page you have to adapt settings a bit otherwise the
"Just slug" permalink will swallow any CMS page you create.

To avoit this add the following settings to you project::

    BLOG_PERMALINKS = (
        ('full_date', _('Full date')),
        ('short_date', _('Year /  Month')),
        ('category', _('Category')),
    )
    BLOG_PERMALINKS_URLS = {
        'full_date': r'^(?P<year>\d{4})/(?P<month>\d{1,2})/(?P<day>\d{1,2})/(?P<slug>\w[-\w]*)/$',
        'short_date': r'^(?P<year>\d{4})/(?P<month>\d{1,2})/(?P<slug>\w[-\w]*)/$',
        'category': r'^(?P<category>\w[-\w]*)/(?P<slug>\w[-\w]*)/$',
    }

Notice that the last permalink type is no longer present.

Then, pick any of the three remaining permalink types in the layout section of the apphooks config
linked ot the home page (see http://yoursite.com/admin/djangocms_blog/blogconfig/).'

Menu
++++

``djangocms_blog`` provides support for django CMS menu framework.

By default all the categories and posts are added to the menu, in a hierarchical structure.

It is possibile to configure per Apphook, whether the menu includes post and categories
(the default), only categories, only posts or no item.

If "post and categories" or "only categories" are set, all the posts not associated with a
category are not added to the menu.

Templates
+++++++++

To ease the template customisations a ``djangocms_blog/base.html`` template is
used by all the blog templates; the templates itself extends a ``base.html``
template; content is pulled in the ``content`` block.
If you need to define a different base template, or if your base template does
not defines a ``content`` block, copy in your template directory
``djangocms_blog/base.html`` and customise it according to your needs; the
other application templates will use the newly created base template and
will ignore the bundled one.

Templates set
+++++++++++++

By using **Apphook configuration** you can define a different templates set.
To use this feature provide a directory name in **Template prefix** field in
the **Apphook configuration** admin (in *Layout* section): it will be the
root of your custom templates set.

.. _auto_setup:

Auto setup
++++++++++

``djangocms_blog`` can install and configue itself if it does not find any
attached instance of itself.
This feature is enable by default and will create:

* a ``BlogConfig`` with default values
* a ``Blog`` CMS page and will attach ``djangocms_blog`` instance to it
* a **home page** if no home is found.

All the items will be created in every language configured for the website
and the pages will be published. If not using **aldryn-apphook-reload** or
**django CMS 3.2** auto-reload middleware you are required to reload the
project instance after this.
This will only work for the current website as detected by
``Site.objects.get_current()``.


The auto setup is execute once for each server start but it will skip any
action if a ``BlogConfig`` instance is found.


Sitemap
+++++++

``djangocms_blog`` provides a sitemap for improved SEO indexing.
Sitemap returns all the published posts in all the languages each post is available.

The changefreq and priority is configurable per-apphook (see ``BLOG_SITEMAP_*`` in
`Global settings <settings>`_).

To add the blog Sitemap, add the following code to the project ``urls.py``::


    from cms.sitemaps import CMSSitemap
    from djangocms_blog.sitemaps import BlogSitemap


    urlpatterns = patterns(
        '',
        ...
        url(r'^sitemap\.xml$', 'django.contrib.sitemaps.views.sitemap',
            {'sitemaps': {
                'cmspages': CMSSitemap, 'blog': BlogSitemap,
            }
        }),
    )

Multisite
+++++++++

django CMS blog provides full support for multisite setups.

Each blog post can be assigned to none, one or more sites: if no site is selected, then
it's visible on all sites.

This is matched with and API that allows to restrict users to only be able to edit
blog posts only for some sites.

To implement this API, you must add a ``get_sites`` method on the user model which
returns a queryset of sites the user is allowed to add posts to.

Example::

    class CustomUser(AbstractUser):
        sites = models.ManyToManyField('sites.Site')

        def get_sites(self):
            return self.sites


django CMS 3.2+ Wizard
++++++++++++++++++++++

django CMS 3.2+ provides a content creation wizard that allows to quickly created supported
content types, such as blog posts.

For each configured Apphook, a content type is added to the wizard.

Some issues with multiple registrations raising django CMS ``AlreadyRegisteredException``
hae been reported; to handle these cases gracefully, the exception is swallowed
when Django ``DEBUG == True`` avoiding breaking production websites. In these cases they
wizard may not show up, but the rest will work as intended.

django-knocker
++++++++++++++

``djangocms-blog`` is integrated with `django-knocker <https://github.com/nephila/django-knocker>`_
to provide real time desktop notifications.

See `django-knocker documentation <https://django-knocker.readthedocs.org/>`_ for how to configure
knocker.
