Does anyone know how I would go about conditionally raising an
exception in a decorator (or any returned function for that matter)?
For example:
def decorator(arg):
def raise_exception(fn):
raise Exception
return raise_exception
class some_class(object):
@raise_exception
def some_method(self)
print "An exception should be raised when I'm called, but not
when I'm defined"
The intent of the above code is that an exception should be raised if
some_method is ever called. It seems, however, since the decorator
function is executed on import, the raise statement is executed, and I
the exception gets thrown whenever the module is imported, rather than
when the method is called. Does anyone have a clue how I might go
about doing this?
Thank you in advance,
Alex.
