Simply: you don't. Of course you can build somewhat obscure python expressions into ZTP tal attributes, but as often, its much simpler in a python script: from AccessControl import getSecurityManager return getSecurityManager().getUser().has_role("Authenticated") Regards Tino

It works as far as it return 1 or 0, but my tal:condtion doesn't work: <div style="margin-top:0.5em" tal:condtion="here/Scripts/isAuthentificated" > [...] </div> What is wrong? Thanks, Florian

What is wrong? You made a typo, it must be tal:condition, not tal:condtion

This was not the error, it still does not work. (I made the typo only on the email, not in the real code). Thx, Florian

Sorry, ok, it's misspelled. But it's the script ID is also misspelled, this shouldn't be the problem. Florian

Sorry, but this is _impossible_. tal:condition evaluates the "truthness" of an expression just like python does. So 0, "", [], {}, None are all false. The Script returns 0 or 1, so it fits into this model. (If unsure, check with repr() to see if its 0 or "0") Even python2.3s real true/false should be supported by tal:condition - since it uses "if" internally. So I cannot really see why it is not working. Apparently your pagetemplate or zope installation is broken or you arent using a Page Template at all (File? DTML-whatever?) Regards Tino

Sorry, it was my fault. It is working correctly. I just forgot a not: because I want to have the text rendered it the user is not logged in. Sorry, sorry! Florian
