Nodes
-----
-:class:`Node`\ s are the basic building blocks of a website using Philo. They define the URL hierarchy and connect each URL to a :class:`View` subclass instance which is used to generate an HttpResponse.
-
-.. class:: Node
-
- :class:`!Node` subclasses :class:`TreeEntity`. It defines the following additional methods and attributes:
-
- .. attribute:: view
-
- :class:`GenericForeignKey` to a non-abstract subclass of :class:`View`
-
- .. attribute:: accepts_subpath
-
- A property shortcut for :attr:`self.view.accepts_subpath <View.accepts_subpath>`
-
- .. method:: render_to_response(request[, extra_context=None])
-
- This is a shortcut method for :meth:`View.render_to_response`
-
- .. method:: get_absolute_url([request=None, with_domain=False, secure=False])
-
- This is essentially a shortcut for calling :meth:`construct_url` without a subpath - which will return the URL of the Node.
-
- .. method:: construct_url([subpath="/", request=None, with_domain=False, secure=False])
-
- This method will do its best to construct a URL based on the Node's location. If with_domain is True, that URL will include a domain and a protocol; if secure is True as well, the protocol will be https. The request will be used to construct a domain in cases where a call to :meth:`Site.objects.get_current` fails.
-
- Node urls will not contain a trailing slash unless a subpath is provided which ends with a trailing slash. Subpaths are expected to begin with a slash, as if returned by :func:`django.core.urlresolvers.reverse`.
-
- :meth:`construct_url` may raise the following exceptions:
-
- - :class:`NoReverseMatch` if "philo-root" is not reversable -- for example, if :mod:`philo.urls` is not included anywhere in your urlpatterns.
- - :class:`Site.DoesNotExist <ObjectDoesNotExist>` if with_domain is True but no :class:`Site` or :class:`RequestSite` can be built.
- - :class:`AncestorDoesNotExist` if the root node of the site isn't an ancestor of the node constructing the URL.

Views

Abstract View Models
++++++++++++++++++++
-.. class:: View
-
- :class:`!View` is an abstract model that represents an item which can be "rendered", either in response to an :class:`HttpRequest` or as a standalone. It subclasses :class:`Entity`, and defines the following additional methods and attributes:
-
- .. attribute:: accepts_subpath
-
- Defines whether this :class:`View` can handle subpaths. Default: ``False``
-
- .. method:: handles_subpath(subpath)
-
- Returns True if the the :class:`View` handles the given subpath, and False otherwise.
-
- .. attribute:: nodes
-
- A generic relation back to nodes.
-
- .. method:: reverse([view_name=None, args=None, kwargs=None, node=None, obj=None])
-
- If :attr:`accepts_subpath` is True, try to reverse a URL using the given parameters using ``self`` as the urlconf.
-
- If ``obj`` is provided, :meth:`get_reverse_params` will be called and the results will be combined with any ``view_name``, ``args``, and ``kwargs`` that may have been passed in.
-
- This method will raise the following exceptions:
-
- - :class:`ViewDoesNotProvideSubpaths` if :attr:`accepts_subpath` is False.
- - :class:`ViewCanNotProvideSubpath` if a reversal is not possible.
-
- .. method:: get_reverse_params(obj)
-
- This method is not implemented on the base class. It should return a ``view_name``, ``args``, ``kwargs`` tuple suitable for reversing a url for the given ``obj`` using ``self`` as the urlconf. If a reversal will not be possible, this method should raise :class:`ViewCanNotProvideSubpath`.
- .. method:: attributes_with_node(node)
+.. autoclass:: View
+ :show-inheritance:
+ :members:
- Returns a :class:`QuerySetMapper` using the :class:`node <Node>`'s attributes as a passthrough.
-
- .. method:: render_to_response(request[, extra_context=None])
-
- Renders the :class:`View` as an :class:`HttpResponse`. This will raise :const:`philo.exceptions.MIDDLEWARE_NOT_CONFIGURED` if the `request` doesn't have an attached :class:`Node`. This can happen if :class:`philo.middleware.RequestNodeMiddleware` is not in :setting:`settings.MIDDLEWARE_CLASSES` or if it is not functioning correctly.
-
- :meth:`!render_to_response` will send the :obj:`view_about_to_render <philo.signals.view_about_to_render>` signal, then call :meth:`actually_render_to_response`, and finally send the :obj:`view_finished_rendering <philo.signals.view_finished_rendering>` signal before returning the ``response``.
-
- .. method:: actually_render_to_response(request[, extra_context=None])
-
- Concrete subclasses must override this method to provide the business logic for turning a ``request`` and ``extra_context`` into an :class:`HttpResponse`.
-
-.. class:: MultiView
-
- :class:`!MultiView` is an abstract model which represents a section of related pages - for example, a :class:`~philo.contrib.penfield.BlogView` might have a foreign key to :class:`Page`\ s for an index, an entry detail, an entry archive by day, and so on. :class:`!MultiView` subclasses :class:`View`, and defines the following additional methods and attributes:
-
- .. attribute:: accepts_subpath
-
- Same as :attr:`View.accepts_subpath`. Default: ``True``
-
- .. attribute:: urlpatterns
-
- Returns urlpatterns that point to views (generally methods on the class). :class:`!MultiView`\ s can be thought of as "managing" these subpaths.
-
- .. method:: actually_render_to_response(request[, extra_context=None])
-
- Resolves the remaining subpath left after finding this :class:`View`'s node using :attr:`self.urlpatterns <urlpatterns>` and renders the view function (or method) found with the appropriate args and kwargs.
-
- .. method:: get_context()
-
- Hook for providing instance-specific context - such as the value of a Field - to all views.
-
- .. method:: basic_view(field_name)
-
- Given the name of a field on ``self``, accesses the value of that field and treats it as a :class:`View` instance. Creates a basic context based on :meth:`get_context` and any extra_context that was passed in, then calls the :class:`View` instance's :meth:`~View.render_to_response` method. This method is meant to be called to return a view function appropriate for :attr:`urlpatterns`.

Concrete View Subclasses
++++++++++++++++++++++++
-.. class:: Redirect
-
- A :class:`View` subclass. Defines a 301 or 302 redirect to a different url on an absolute or relative path.
-
- .. attribute:: STATUS_CODES
-
- A choices tuple of redirect status codes (temporary or permanent).
-
- .. attribute:: status_code
-
- An :class:`IntegerField` which uses :attr:`STATUS_CODES` as its choices. Determines whether the redirect is considered temporary or permanent.
-
- .. attribute:: target_node
-
- An optional :class:`ForeignKey` to a :class:`Node`. If provided, that node will be used as the basis for the redirect.
-
- .. attribute:: url_or_subpath
-
- A :class:`CharField` which may contain an absolute or relative URL. This will be validated with :class:`philo.validators.RedirectValidator`.
-
- .. attribute:: reversing_parameters
-
- A :class:`~philo.models.fields.JSONField` instance. If the value of :attr:`reversing_parameters` is not None, the :attr:`url_or_subpath` will be treated as the name of a view to be reversed. The value of :attr:`reversing_parameters` will be passed into the reversal as args if it is a list or as kwargs if it is a dictionary.
+.. autoclass:: Redirect
+ :show-inheritance:
+ :members:
- .. attribute:: target_url
-
- Calculates and returns the target url based on the :attr:`target_node`, :attr:`url_or_subpath`, and :attr:`reversing_parameters`.
-
- .. method:: actually_render_to_response(request[, extra_context=None])
-
- Returns an :class:`HttpResponseRedirect` to :attr:`self.target`.
-
-.. class:: File
-
- A :class:`View` subclass. Stores an arbitrary file.
-
- .. attribute:: mimetype
-
- Defines the mimetype of the uploaded file. This will not be validated.
-
- .. attribute:: file
-
- Contains the uploaded file. Files are uploaded to ``philo/files/%Y/%m/%d``.
-
- .. method:: __unicode__()
-
- Returns the name of :attr:`self.file <file>`.

Pages
*****
-:class:`Page`\ s are the most frequently used :class:`View` subclass. They define a basic HTML page and its associated content. Each :class:`Page` renders itself according to a :class:`Template`. The :class:`Template` may contain :ttag:`container` tags, which define related :class:`Contentlet`\ s and :class:`ContentReference`\ s for any page using that :class:`Template`.
-
-.. class:: Page
-
- A :class:`View` subclass. Represents a page - something which is rendered according to a template. The page will have a number of related Contentlets depending on the template selected - but these will appear only after the page has been saved with that template.
-
- .. attribute:: template
-
- A :class:`ForeignKey` to the :class:`Template` used to render this :class:`Page`.
-
- .. attribute:: title
-
- The name of this page. Chances are this will be used for organization - i.e. finding the page in a list of pages - rather than for display.
-
- .. attribute:: containers
-
- Returns :attr:`self.template.containers <Template.containers>` - a tuple containing the specs of all :ttag:`container`\ s defined in the :class:`Template`. The value will be cached on the instance so that multiple accesses will be less expensive.
-
- .. method:: render_to_string([request=None, extra_context=None])
-
- In addition to rendering as an :class:`HttpResponse`, a :class:`Page` can also render as a string. This means, for example, that :class:`Page`\ s can be used to render emails or other non-HTML-related content with the same :ttag:`container`-based functionality as is used for HTML.
-
- .. method:: actually_render_to_response(request[, extra_context=None])
-
- Returns an :class:`HttpResponse` with the content of the :meth:`render_to_string` method and the mimetype set to :attr:`self.template.mimetype <Template.mimetype>`.
-
- .. clean_fields(self[, exclude=None)
-
- This is an override of the default model clean_fields method. Essentially, in addition to validating the fields, this method validates the :class:`Template` instance that is used to render this :class:`Page`. This is useful for catching template errors before they show up as 500 errors on a live site.
-
- .. method:: __unicode__()
-
- Returns :meth:`self.title <title>`
-
-.. class:: Template
-
- Subclasses :class:`TreeModel`. Represents a database-driven django template. Defines the following additional methods and attributes:
-
- .. attribute:: name
-
- The name of the template. Used for organization and debugging.
-
- .. attribute:: documentation
-
- Can be used to let users know what the template is meant to be used for.
-
- .. attribute:: mimetype
-
- Defines the mimetype of the template. This is not validated. Default: ``text/html``.
-
- .. attribute:: code
-
- An insecure :class:`~philo.models.fields.TemplateField` containing the django template code for this template.
-
- .. attribute:: containers
-
- Returns a tuple where the first item is a list of names of contentlets referenced by containers, and the second item is a list of tuples of names and contenttypes of contentreferences referenced by containers. This will break if there is a recursive extends or includes in the template code. Due to the use of an empty Context, any extends or include tags with dynamic arguments probably won't work.
-
- .. method:: __unicode__()
-
- Returns the results of the :meth:`~TreeModel.get_path` method, using the "name" field and a chevron joiner.
-
-.. class:: Contentlet
-
- Defines a piece of content on a page. This content is treated as a secure :class:`~philo.models.fields.TemplateField`.
-
- .. attribute:: page
-
- The page which this :class:`Contentlet` is related to.
-
- .. attribute:: name
-
- This represents the name of the container as defined by a :ttag:`container` tag.
-
- .. attribute:: content
-
- A secure :class:`~philo.models.fields.TemplateField` holding the content for this :class:`Contentlet`. Note that actually using this field as a template requires use of the :ttag:`include_string` template tag.
-
- .. method:: __unicode__()
-
- Returns :attr:`self.name <name>`
-
-.. class:: ContentReference
-
- Defines a model instance related to a page.
-
- .. attribute:: page
-
- The page which this :class:`ContentReference` is related to.
-
- .. attribute:: name
-
- This represents the name of the container as defined by a :ttag:`container` tag.
+.. automodule:: philo.models.pages
- .. attribute:: content
+.. autoclass:: Page
+ :members:
+ :show-inheritance:
- A :class:`GenericForeignKey` to a model instance. The content type of this instance is defined by the :ttag:`container` tag which defines this :class:`ContentReference`.
