Function Details

dispatch_error(controller, tg_source, tg_errors, tg_exceptions, *args, **kw)

source code

Dispatch error.

Error handler is a function registered via register_handler or if no such decorator was applied, the method triggering the error.

Decorators:

@abstract()

dispatch_error_adaptor(func)

source code

Construct a signature isomorphic to dispatch_error.

The actual handler will receive only arguments explicitly declared, and a possible tg_format parameter.

register_handler(handler=None, rules=None)

source code

If handler is not given, method is considered its own error handler.

rules can be a string containing an arbitrary logical Python expression to be used as dispatch rule allowing multiple error handlers for a single method.

register_handler decorator is an invariant.
