Hi Alessandro,
And how would it be this way? I don't know exactly how "after_render"
has to be used. As far as I know, you define a function with a
"response" parameter and then a decorator "after_render" passing that
function in.
def _after_render(r):
# something to be done
r.content_type = 'application/pdf'
r.body = to_pdf(r.body)
@expose('foo.html')
@after_render(_after_render)
def foo(self, *args, **kwargs):
return dict(....)
is it correct? I was trying this way but...can I modify "response"
inside "_after_render"? I thought it was not possible...
Thanks
León
