Description: =========================
        django-markitup-field
        =========================
        
        An implementation of a custom MarkupField for Django.  A MarkupField is in
        essence a TextField with an associated markup format and `MarkItUp!`_ markup
        editor widget with AJAX preview.  The field also caches its rendered value on
        the assumption that disk space is cheaper than CPU cycles in a web application.
        
        Based on `django-markupfield <http://github.com/jamesturk/django-markupfield>`_
        and `django-markitup <http://github.com/carljm/django-markitup>`_.
        
        .. _MarkItUp!: http://markitup.jaysalvat.com/
        
        Installation
        ============
        
        The recommended way to install django-markitup-field is with
        `pip <http://pypi.python.org/pypi/pip>`_
        
        Install from PyPI with ``easy_install`` or ``pip``::
        
            pip install django-markitup-field
        
        or get the `in-development version`_::
        
            pip install django-markitup-field==tip
        
        .. _in-development version: http://github.com/dimka665/django-markitup-field
        
        It is not necessary to add ``'markitup_field'`` to your ``INSTALLED_APPS``, it
        merely needs to be on your ``PYTHONPATH``.
        
        If you want to use AJAX-based preview, add
        ``url(r'^markitup/', include('markitup.urls'))`` in your root URLconf.
        
        Requirements
        ------------
        
        django-markitup-field depends on a relatively current version of Django
        (tested with 1.3-1.4, may work with 1.2 but not guaranteed) and libraries for
        whichever markup options you wish to include.
        
        
        Settings
        ========
        
        You can define the ``MARKUP_FILTERS`` setting, a mapping of strings
        to callables that 'render' a markup type::
        
            import markdown
            from docutils.core import publish_parts
        
            def render_rest(markup):
                parts = publish_parts(source=markup, writer_name="html4css1")
                return parts["fragment"]
        
            MARKUP_FILTERS = (
                ('markdown', markdown.markdown),
                ('restructuredtext', render_rest),
            )
        
        If you do not define a ``MARKUP_FILTERS`` then one is provided with the
        following markup types available:
        
        html:
            allows HTML, potentially unsafe
        text:
            plain text markup, calls urlize and replaces text with linebreaks
        markdown:
            default `markdown`_ renderer (only if `python-markdown`_ is installed)
        restructuredtext:
            default `ReST`_ renderer (only if `docutils`_ is installed)
        textile:
            default `textile`_ renderer (only if `textile`_ is installed)

        Usage
        =====
        
        Using MarkupField is relatively easy, it can be used in any model definition::
        
            from django.db import models
            from markitup_field.fields import MarkupField
        
            class Article(models.Model):
                title = models.CharField(max_length=100)
                slug = models.SlugField(max_length=100)
                body = MarkupField()
        
        ``Article`` objects can then be created with any markup type defined in
        ``MARKUP_FORMATS``::
        
            Article.objects.create(title='some article', slug='some-article',
                                   body='*fancy*', body_markup_format='markdown')
        
        You will notice that a field named ``body_markup_format`` exists that you did
        not declare, MarkupField actually creates two extra fields. ``body_markup_format``
        This field is always named according to the name of the declared ``MarkupField``.
        
        Arguments
        ---------
        
        ``MarkupField`` also takes three optional arguments.  Either
        ``default_markup_format`` and ``markup_format`` arguments may be specified but
        not both.
        
        ``default_markup_format``:
            Set a markup_type that the field will default to if one is not specified.
            It is still possible to edit the markup type attribute and it will appear
            by default in ModelForms.
        
        ``markup_format``:
            Set markup type that the field will always use, ``editable=False`` is set
            on the hidden field so it is not shown in ModelForms.
        
        ``markup_choices``:
            A replacement list of markup choices to be used in lieu of
            ``MARKUP_FORMATS`` on a per-field basis.
        
        ``escape_html``:
            A flag (False by default) indicating that the input should be regarded
            as untrusted and as such will be run through Django's ``escape`` filter.
        
        ``rendered_field_name``:
            Name for field with rendered content. If it is set to None,
            then it named <field_name>_rendered
        
        
        Examples
        ~~~~~~~~
        
        ``MarkupField`` that will default to using markdown but allow the user a choice::
        
            MarkupField(default_markup_type='markdown')
        
        ``MarkupField`` that will use textile and not provide a choice on forms::
        
            MarkupField(markup_type='textile')
        
        ``MarkupField`` that will use a custom set of renderers::
        
            CUSTOM_RENDERERS = (
                ('markdown', markdown.markdown),
                ('wiki', my_wiki_render_func)
            )
            MarkupField(markup_choices=CUSTOM_RENDERERS)
        
        Accessing a MarkupField on a model
        ----------------------------------
        
        When accessing an attribute of a model that was declared as a ``MarkupField``
        a special ``Markup`` object is returned.  The ``Markup`` object has three
        parameters:
        
        ``raw``:
            The unrendered markup.
        ``markup_format``:
            The markup type.
        ``rendered``:
            The rendered HTML version of ``raw``, this attribute is read-only.
        
        This object has a ``__unicode__`` method that calls
        ``django.utils.safestring.mark_safe`` on ``rendered`` allowing MarkupField
        objects to appear in templates as their rendered selfs without any template
        tag or having to access ``rendered`` directly.
        
        Assuming the ``Article`` model above::
        
            >>> a = Article.objects.all()[0]
            >>> a.body.raw
            u'*fancy*'
            >>> a.body.markup_type
            u'markdown'
            >>> a.body.rendered
            u'<p><em>fancy</em></p>'
            >>> print unicode(a.body)
            <p><em>fancy</em></p>
        
        Assignment to ``a.body`` is equivalent to assignment to ``a.body.raw`` and
        assignment to ``a.body_markup_format`` is equivalent to assignment to
        ``a.body.markup_format``.
        
        .. note::
            a.body.rendered is only updated when a.save() is called
