                                                   TAPRenderer

A renderer speaking all of TAP (including sync, async, and VOSI).

Basically, this just dispatches to the sync and async resources.

Method Details

renderHTTP(self, ctx)

Overrides: nevow.rend.Page.renderHTTP

gatherUploadFiles(self, request)

creates a files attribute on request, containing all uploaded files.

The upload files are removed from args, which is good since we don't want to serialize those in the parameters dictionary.

This method inspects all upload parameters and converts the referenced arguments to cgi-like files as necessary. Missing uploads will be noticed here, and the request will be rejected.

Of course, all that hurts if someone manages to upload from REQUEST -- but that's their fault then.

locateChild(self, ctx, segments)

Locate a child page of this one. ctx is a nevow.context.PageContext representing the parent Page, and segments is a tuple of each element in the URI. An tuple (page, segments) should be returned, where page is an instance of nevow.rend.Page and segments a tuple representing the remaining segments of the URI. If the child is not found, return NotFound instead.

locateChild is designed to be easily overridden to perform fancy lookup tricks. However, the default locateChild is useful, and looks for children in three places, in this order:

in a dictionary, self.children
a member of self named child_<childname>. This can be either an attribute or a method. If an attribute, it should be an object which can be adapted to IResource. If a method, it should take the context and return an object which can be adapted to IResource.
by calling self.childFactory(ctx, name). Name is a single string instead of a tuple of strings. This should return an object that can be adapted to IResource.

Overrides: nevow.rend.FreeformChildMixin.locateChild
