Method Details

init(self)
(Constructor)

Initialize.

Overrides:: twisted.web.resource.Resource.__init__ (inherited documentation)

render(self, request)

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.
