t.w.r.ErrorPage(Resource) : class documentation

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

Known subclasses: twisted.web.error.ErrorPage, twisted.web.resource.ForbiddenResource, twisted.web.resource.NoResource

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 VariablestemplateA str which will have a dictionary interpolated into it to generate the response body. The dictionary has the following keys:
codeAn integer status code which will be used for the response.
briefA short string which will be included in the response body.
detailA 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 __init__(self, status, brief, detail): (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 getChild(self, chnam, 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.
