twisted.web.resource.ErrorPage : API documentation

ErrorPage is a resource which responds with a particular (parameterized) status and a body consisting of HTML containing some descriptive text. This is useful for rendering simple error pages.

Instance Variables	template	A `str` which will have a dictionary interpolated into it to generate the response body. The dictionary has the following keys: `"code"`: The status code passed to `ErrorPage.__init__`. `"brief"`: The brief description passed to `ErrorPage.__init__`. `"detail"`: The detailed description passed to `ErrorPage.__init__`.
	code	An integer status code which will be used for the response.
	brief	A short string which will be included in the response body.
	detail	A longer string which will be included in the response body.

Method	__init__	Initialize.
Method	render	Render a given resource. See `IResource`'s render method.
Method	getChild	Retrieve a 'child' resource from me.

def render(self, request): (source)

from twisted.web.resource.IResource

overrides twisted.web.resource.Resource.render

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 getChild(self, chnam, request): (source)

overrides twisted.web.resource.Resource.getChild

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.

Parameters	path	a string, describing the child
	request	a twisted.web.server.Request specifying meta-information about the request that is being made for this child.
