t.w.w.Gadget(resource.Resource) : class documentation

Part of twisted.web.widgets View Source View In Hierarchy

I am a collection of Widgets, to be rendered through a Page Factory. self.pageFactory should be a Resource that takes a Widget in its constructor. The default is twisted.web.widgets.WidgetPage.
Method __init__ Initialize.
Method render Render a given resource. See IResource's render method.
Method putWidget Gadget.putWidget(path, widget) Add a Widget to this Gadget. It will be rendered through the pageFactory associated with this Gadget, whenever 'path' is requested.
Method addFile Gadget.addFile(path) Add a static path to this Gadget. This method is obsolete, use Gadget.putPath instead.
Method putPath Gadget.putPath(path, pathname) Add a static path to this Gadget. Whenever 'path' is requested, twisted.web.static.File(pathname) is sent.
Method getWidget Undocumented
Method pageFactory No summary
Method getChild Retrieve a 'child' resource from me.

Inherited from Resource:

Method listStaticNames Undocumented
Method listStaticEntities Undocumented
Method listNames Undocumented
Method listEntities Undocumented
Method listDynamicNames Undocumented
Method listDynamicEntities Undocumented
Method getStaticEntity Undocumented
Method getDynamicEntity Undocumented
Method delEntity Undocumented
Method reallyPutEntity Undocumented
Method getChildWithDefault Retrieve a static or dynamically generated child resource from me.
Method getChildForRequest Undocumented
Method putChild Register a static child.
Method render_HEAD Default handling of HEAD method.
def __init__(self): (source)
Initialize.
def render(self, request): (source)

Render a given resource. See IResource's render method.

I delegate to methods of self with the form 'render_METHOD' where METHOD is the HTTP that was used to make the request. Examples: render_GET, render_HEAD, render_POST, and so on. Generally you should implement those methods instead of overriding this one.

render_METHOD methods are expected to return a string which will be the rendered page, unless the return value is twisted.web.server.NOT_DONE_YET, in which case it is this class's responsibility to write the results to request.write(data), then call request.finish().

Old code that overrides render() directly is likewise expected to return a string or NOT_DONE_YET.
def putWidget(self, path, widget): (source)
Gadget.putWidget(path, widget) Add a Widget to this Gadget. It will be rendered through the pageFactory associated with this Gadget, whenever 'path' is requested.
def addFile(self, path): (source)
Gadget.addFile(path) Add a static path to this Gadget. This method is obsolete, use Gadget.putPath instead.
def putPath(self, path, pathname): (source)
Gadget.putPath(path, pathname) Add a static path to this Gadget. Whenever 'path' is requested, twisted.web.static.File(pathname) is sent.
def getWidget(self, path, request): (source)
Undocumented
def pageFactory(self, *args, **kwargs): (source)
Gadget.pageFactory(*args, **kwargs) -> Resource By default, this method returns self.page(*args, **kwargs). It is only for backwards-compatibility -- you should set the 'pageFactory' attribute on your Gadget inside of its __init__ method.
def getChild(self, path, request): (source)

Retrieve a 'child' resource from me.

Implement this to create dynamic resource generation -- resources which are always available may be registered with self.putChild().

This will not be called if the class-level variable 'isLeaf' is set in your subclass; instead, the 'postpath' attribute of the request will be left as a list of the remaining path elements.

For example, the URL /foo/bar/baz will normally be:
 | site.resource.getChild('foo').getChild('bar').getChild('baz').
However, if the resource returned by 'bar' has isLeaf set to true, then the getChild call will never be made on it.
Parameterspatha string, describing the child
requesta twisted.web.server.Request specifying meta-information about the request that is being made for this child.
