[TurboGears] Breaking change in r701 (validators and error handling)

[Simon Belak]

Hi,
as of r701 methods using validators have to declare an error handler in 
some way. This can be done either by adding parameter tg_errors to each 
method or using controllers.error_handler decorator.

    @expose(validators={...})
    def foo(self, baz="", bar="")
       ...

should therefore be changed to

    @expose(validators={...})
    @error_handler()
    def foo(self, baz="", bar="")
       ...

or

    @expose(validators={...})
    def foo(self, baz="", bar="", tg_errors=None)
       ...

For further examples see turbogears/tests/test_errorhandling.py or 
ticket #258 [1] and fear not, proper documentation is on the way. ;)


Cheers,
Simon
