This project has reached the end of its development as CMS framework. It only receives low maintenance to continue running existing websites. Feel free to browse the code, but please use other Django-based CMS frameworks such as Wagtail CMS when you start a new project.

django-fluent-pages

This is a stand-alone module, which provides a flexible, scalable CMS with custom node types, and flexible block content.

Features:

A fully customizable page hierarchy.
Support for multilingual websites.
Support for multiple websites in a single database.
Fast SEO-friendly page URLs.
SEO optimized (meta keywords, description, title, 301-redirects, sitemaps integration).
Plugin support for custom page types, which:

Integrate application logic in page trees.

Integrate advanced block editing (via as django-fluent-contents).

For more details, see the documentation at Read The Docs.

Page tree customization

This module provides a page tree, where each node type can be a different model. This allows developers like yourself to structure your site tree as you see fit. For example:

Build a tree structure of RST pages, by defining a RstPage type.
Build a tree with widget-based pages, by integrating django-fluent-contents.
Build a \"product page\", which exposes all products as sub nodes.
Build a tree of a homepage, subsection, and article node, each with custom fields like professional CMSes have.

Each node type can have it\'s own custom fields, attributes and rendering.

In case you\'re building a custom CMS, this module might just be suited for you, since it provides the tree for you, without bothering with anything else. The actual page contents is defined via page type plugins.

Installation

First install the module, preferably in a virtual environment:

pip install django-fluent-pages

All dependencies will be automatically installed.

Configuration

You can also use the ready-made template:

mkdir my-website.com
cd my-website.com
django-admin.py startproject mywebsite . -e py,rst,example,gitignore --template=https://github.com/edoburu/django-project-template/archive/django-fluent.zip

Or create a new project:

cd ..
django-admin.py startproject fluentdemo

To have a standard setup with django-fluent-contents integrated, use:

INSTALLED_APPS += (
    # The CMS apps
    'fluent_pages',

    # Required dependencies
    'mptt',
    'parler',
    'polymorphic',
    'polymorphic_tree',
    'slug_preview',

    # Optional widget pages via django-fluent-contents
    'fluent_pages.pagetypes.fluentpage',
    'fluent_contents',
    'fluent_contents.plugins.text',
    'django_wysiwyg',

    # Optional other CMS page types
    'fluent_pages.pagetypes.redirectnode',

    # enable the admin
    'django.contrib.admin',
)

DJANGO_WYSIWYG_FLAVOR = "yui_advanced"

Note each CMS application is optional. Only fluent_pages and mptt are required. The remaining apps add additional functionality to the system.

In urls.py:

urlpatterns += patterns('',
    url(r'', include('fluent_pages.urls'))
)

The database can be created afterwards:

./manage.py migrate
./manage.py runserver

Custom page types

The key feature of this module is the support for custom node types. Take a look in the existing types at fluent_pages.pagetypes to see how it\'s being done.

It boils down to creating a package with 2 files:

The models.py file should define the custom node type, and any fields it has:

from django.db import models
from django.utils.translation import ugettext_lazy as _
from fluent_pages.models import HtmlPage
from mysite.settings import RST_TEMPLATE_CHOICES


class RstPage(HtmlPage):
    """
    A page that renders RST code.
    """
    rst_content = models.TextField(_("RST contents"))
    template = models.CharField(_("Template"), max_length=200, choices=RST_TEMPLATE_CHOICES)

    class Meta:
        verbose_name = _("RST page")
        verbose_name_plural = _("RST pages")

A page_type_plugins.py file that defines the metadata, and rendering:

from fluent_pages.extensions import PageTypePlugin, page_type_pool
from .models import RstPage


@page_type_pool.register
class RstPagePlugin(PageTypePlugin):
    model = RstPage
    sort_priority = 10

    def get_render_template(self, request, rstpage, **kwargs):
        return rstpage.template

A template could look like:

{% extends "base.html" %}
{% load markup %}

{% block headtitle %}{{ page.title }}{% endblock %}

{% block main %}
  <h1>{{ page.title }}</h1>

  <div id="content">
    {{ page.rst_content|restructuredtext }}
  </div>
{% endblock %}

Et, voila: with very little code a custom CMS was just created.

Optionally, a model_admin can also be defined, to have custom field layouts or extra functionality in the edit or delete page.

Plugin configuration

The plugin can define the following attributes:

model - the model for the page type
model_admin - the custom admin to use (must inherit from PageAdmin)
render_template - the template to use for rendering
response_class - the response class (by default TemplateResponse)
is_file - whether the node represents a file, and shouldn\'t end with a slash.
can_have_children - whether the node type is allowed to have child nodes.
urls - a custom set of URL patterns for sub pages (either a module name, or patterns() result).
sort_priority - a sorting order in the \"add page\" dialog.

It can also override the following functions:

get_response(self, request, page, **kwargs) - completely redefine the response, instead of using response_class, render_template, etc..
get_render_template(self, request, page, **kwargs) - return the template to render, by default this is render_template.
get_context(self, request, page, **kwargs) - return the template context for the node.

Details about these attributes is explained in the documentation.

Application nodes

As briefly mentioned above, a page type can have it\'s own set of URL patterns, via the urls attribute. This allows implementing page types such as a \"product page\" in the tree, which automatically has all products from the database as sub pages. The provides example module demonstrates this concept.

The URL patterns start at the full path of the page, so it works similar to a regular include() in the URLconf. However, a page type may be added multiple times to the tree. To resolve the URLs, there are 2 functions available:

fluent_pages.urlresolvers.app_reverse() - this reverse() like function locates a view attached to a page.
fluent_pages.urlresolvers.mixed_reverse() - this resolver tries app_reverse() first, and falls back to the standard reverse().

The mixed_reverse() is useful for third party applications which can operate either stand-alone (mounted in the normal URLconf), or operate as page type node in combination with django-fluent-pages. These features are also used by django-fluent-blogs to provide a \"Blog\" page type that can be added to a random point of the tree.

Adding pages to the sitemap

Optionally, the pages can be included in the sitemap. Add the following in urls.py:

from fluent_pages.sitemaps import PageSitemap

sitemaps = {
    'pages': PageSitemap,
}

urlpatterns += patterns('',
    url(r'^sitemap.xml$', 'django.contrib.sitemaps.views.sitemap', {'sitemaps': sitemaps}),
)
