Hello. I want a Python Script that redirects to a ZPT, so that the ZPT can see information generated by the Script. I don't want this information to persist along all the session. Is there any way to do this?
I tried saving the data in the REQUEST object, but it seems that the redirection generates a new REQUEST object for the ZPT and forgets the other one.
That is correct. That's just how redirects work. You have several options, each with advantages and disadvantages: 1) redirect from the script to a URL that includes the necessary information as parameters: context.REQUEST.RESPONSE.redirect("list_html?foo=bar&blah=23") ... you are limited by the length of the query string which cannot grow indefinitely. I forget what the limits are. 2) don't redirect. Call the script from the zpt. <html> <body> <p tal:content="context/foo_script"> </p> </body> </html> This is my preferred solution unless the script must direct the user to several templates in different cases. 3) don't redirect. Call the zpt from the script: return context.list_html(foo="bar", blah=23) ... parameters can be accessed in the page template in the "options" namespace. This is a fine solution except that the URL displayed is that of the script rather than that of the template. You must decide whether this is a problem. Some zopistas seem to have aesthetic objections to calling templates from scripts. It's transparent to the user so I don't see a problem.
