Hi All,
Can anyone show me how to use the operator "and" in the tag <dtml-if> This is how i've used it but it doesn't worked for me. Zope does not give me any error when i tried to execute this code and it also does not execute the intended script.
Your us of "and" is correct, as i see. The dtml-if awaits a correct python expression, that is evaluated to a boolean(compatible) value. Like:
1 and 1 1 1 and 0 0 0 and 1 0 0 and 0 0
So if your get "Permission denied" you know that your expression evaluated to something thats 0 in boolean aka FALSE. (A nonempty string is also a boolean TRUE equivalent in python.)
<dtml-if "level_in=='Development' and AUTHENTICATE_USER.has_role('Development')"> Then execute script <dtml-else> Permission Denied! </dtml-if>
Thanks for any suggestion,
