twisted.web.template : API documentation

Variable	VALID_HTML_TAG_NAMES	A list of recognized HTML tag names, used by the `tag` object.
Variable	TEMPLATE_NAMESPACE	The XML namespace used to identify attributes and elements used by the templating system, which should be removed from the final output document.
Variable	tags	A convenience object which can produce `Tag` objects on demand via attribute access. For example: `tags.div` is equivalent to `Tag("div")`. Tags not specified in `VALID_HTML_TAG_NAMES` will result in an `AttributeError`.
Class	Tag	No summary
Class	slot	Marker for markup insertion in a template.
Class	Comment	A `<!-- -->` comment from a template. Given a separate representation in the DOM so that they may be round-tripped through rendering without losing information.
Class	CDATA	A `<![CDATA[]]>` block from a template. Given a separate representation in the DOM so that they may be round-tripped through rendering without losing information.
Class	CharRef	A numeric character reference. Given a separate representation in the DOM so that non-ASCII characters may be output as pure ASCII.
Class	TagLoader	An `ITemplateLoader` that loads existing `IRenderable` providers.
Class	XMLString	An `ITemplateLoader` that loads and parses XML from a string.
Class	XMLFile	An `ITemplateLoader` that loads and parses XML from a file.
Function	renderElement	Render an element or other `IRenderable`.
Class	Element	Base for classes which can render part of a page.
Function	renderer	Decorate with `renderer` to use methods as template render directives.
Function	flatten	Incrementally write out a string representation of `root` using `write`.
Function	flattenString	Collate a string representation of `root` into a single string.
Class	_NSContext	A mapping from XML namespaces onto their prefixes in the document.
Class	_ToStan	A SAX parser which converts an XML document to the Twisted STAN Document Object Model.
Function	_flatsaxParse	Perform a SAX parse of an XML document with the _ToStan class.
Class	_TagFactory	A factory for `Tag` objects; the implementation of the `tags` object.

def renderElement(request, element, doctype='<!DOCTYPE html>', _failElement=None): (source)

Render an element or other IRenderable.

Parameters	request	The `Request` being rendered to.
	element	An `IRenderable` which will be rendered.
	doctype	A `str` which will be written as the first line of the request, or `None` to disable writing of a doctype. The `string` should not include a trailing newline and will default to the HTML5 doctype `'<!DOCTYPE html>'`.
Returns	NOT_DONE_YET
Present Since	12.1

@exposer
def renderer(): (source)

Decorate with renderer to use methods as template render directives.

For example:

   class Foo(Element):
       @renderer
       def twiddle(self, request, tag):
           return tag('Hello, world.')

   <div xmlns:t="http://twistedmatrix.com/ns/twisted.web.template/0.1">
       <span t:render="twiddle" />
   </div>

Will result in this final output:

   <div>
       <span>Hello, world.</span>
   </div>

def flatten(request, root, write): (source)

Incrementally write out a string representation of root using write.

In order to create a string representation, root will be decomposed into simpler objects which will themselves be decomposed and so on until strings or objects which can easily be converted to strings are encountered.

Parameters	request	A request object which will be passed to the `render` method of any `IRenderable` provider which is encountered.
	root	An object to be made flatter. This may be of type `unicode`, `bytes`, `slot`, `Tag`, `tuple`, `list`, `GeneratorType`, `Deferred`, or something that provides `IRenderable`.
	write	A callable which will be invoked with each `bytes` produced by flattening `root`.
Returns	A `Deferred` which will be called back when `root` has been completely flattened into `write` or which will be errbacked if an unexpected exception occurs.

def flattenString(request, root): (source)

Collate a string representation of root into a single string.

This is basically gluing flatten to a StringIO and returning the results. See flatten for the exact meanings of request and root.

Returns A Deferred which will be called back with a single string as its result when root has been completely flattened into write or which will be errbacked if an unexpected exception occurs.

Parameters	fl	The XML document to be parsed. (type: A file object or filename.)
Returns	a `list` of Stan objects.
