Hi;
I've written this code:
html
body
span tal:define=global number here/quotes/randomNumber/span
tabletrtd
span metal:use-macro=here/en-us/quotes/?number/macros/quote/spanbr /
/td/tr/table
/body
html
...and here's randomNumber, which is an External Method:
def randomNumber(self):
return randrange(1, len(self.objectValues()), 1)
but it throws this error which ends with Iteration over non-sequence. Well,
the folder from which it's supposed to select a quote holds nothing but a
sequential number of page templates (named 1, 2, 3...). What am I doing wrong?
TIA,
Tony
