def getChild(self, path, request): (source)

overridden in twisted.web.woven.page.LivePage, twisted.web.woven.page.Page

Undocumented

def getChildWithDefault(self, path, request): (source)

Return a child with the given name for the given request. This is the external interface used by the Resource publishing machinery. If implementing IResource without subclassing Resource, it must be provided. However, if subclassing Resource, getChild overridden instead.

def __init__(self, m, templateFile=None, templateDirectory=None, template=None, controller=None, doneCallback=None, modelStack=None, viewStack=None, controllerStack=None): (source)

from twisted.web.woven.interfaces.IView

overridden in twisted.web.woven.page.LivePage, twisted.web.woven.page.Page, twisted.web.woven.widgets.Widget

A view must be told what its model is, and may be told what its controller is, but can also look up its controller if none specified.

def setupAllStacks(self): (source)

Undocumented

def setUp(self, request, d): (source)

overridden in twisted.web.woven.widgets.Widget

Undocumented

def setupViewStack(self): (source)

Undocumented

def importViewLibrary(self, namespace): (source)

from twisted.web.woven.interfaces.IView

Import the given object or module into this View's view namespace stack. If the given object or module has a getSubview function or method, it will be called when a node has a view="foo" attribute. If no getSubview method is defined, a default one will be provided which looks for the literal name in the namespace.

def render(self, request, doneCallback=None): (source)

from twisted.web.resource.IResource

Render a request. This is called on the leaf resource for a request. Render must return either a string, which will be sent to the browser as the HTML for the request, or server.NOT_DONE_YET. If NOT_DONE_YET is returned, at some point later (in a Deferred callback, usually) call request.write("<html>") to write data to the request, and request.finish() to send the data to the browser.

def getTemplate(self, request): (source)

Override this if you want to have your subclass look up its template using a different method.

def lookupTemplate(self, request): (source)

overridden in twisted.web.woven.tapestry.TapestryView

Use acquisition to look up the template named by self.templateFile, located anywhere above this object in the heirarchy, and use it as the template. The first time the template is used it is cached for speed.

def handleDocument(self, request, document): (source)

Handle the root node, and send the page if there are no outstanding callbacks when it returns.

def handleOutstanding(self, request): (source)

Undocumented

def recurseChildren(self, request, node): (source)

If this node has children, handle them.

def dispatchResult(self, request, node, result): (source)

Check a given result from handling a node and look up a NodeMutator adapter which will convert the result into a node and insert it into the DOM tree. Return the new node.

def modelChanged(self, changed): (source)

from twisted.web.woven.interfaces.IView

overridden in twisted.web.woven.widgets.Widget

Rerender this view, because our model has changed.

def generate(self, request, node): (source)

overridden in twisted.web.woven.widgets.Widget

Allow a view to be used like a widget. Will look up the template file and return it in place of the incoming node.

def setController(self, controller): (source)

from twisted.web.woven.interfaces.IView

Set the controller that this view is related to.

def setNode(self, node): (source)

overridden in twisted.web.woven.widgets.Widget

Undocumented

def setSubmodel(self, name): (source)

overridden in twisted.web.woven.widgets.Widget

Undocumented

def getNodeModel(self, request, node, submodel): (source)

Get the model object associated with this node. If this node has a model= attribute, call getSubmodel on the current model object. If not, return the top of the model stack.

def getNodeController(self, request, node, submodel, model): (source)

Get a controller object to handle this node. If the node has no controller= attribute, first check to see if there is an IController adapter for our model.

def getSubview(self, request, node, model, viewName): (source)

from twisted.web.woven.interfaces.IView

Get a sub-view from me.

Returns widgets.Widget

def getNodeView(self, request, node, submodel, model): (source)

Undocumented

def handleNode(self, request, node): (source)

Undocumented

def handleControllerResults(self, controllerResult, request, node, controller, view): (source)

Handle a deferred from a controller.

def handleNewNode(self, request, returnNode): (source)

Undocumented

def sendPage(self, request): (source)

Check to see if handlers recorded any errors before sending the page

def setSubviewFactory(self, name, factory, *args, setup=None, **kwargs): (source)

from twisted.web.woven.interfaces.IView

Set the callable "factory", which takes a model and should return a Widget, to be called by the default implementation of getSubview when the viewName "name" is present in the template.

This would generally be used like this:

view.setSubviewFactory("foo", MyFancyWidgetClass)

This is equivalent to:

   def wvfactory_foo(self, request, node, m):
       return MyFancyWidgetClass(m)

Which will cause an instance of MyFancyWidgetClass to be instanciated when template node <div view="foo" /> is encountered.

If setup is passed, it will be passed to new instances returned from this factory as a setup method. The setup method is called each time the Widget is generated. Setup methods take (request, widget, model) as arguments.

This is equivalent to:

   def wvupdate_foo(self, request, widget, model):
       # whatever you want

def __setitem__(self, key, value): (source)

overridden in twisted.web.woven.widgets.Widget

Undocumented

def unlinkViews(self): (source)

Undocumented

def dispatchResultCallback(self, result, request, node): (source)

Deal with a callback from a deferred, checking to see if it is ok to send the page yet or not.

def renderFailure(self, failure, request): (source)
