Is there some way to pass an object from template A to template B via HTML forms?
A <form name="a" action="b" method="post"> <input type="hidden" name="obj" tal:attributes="value here" /> <input type="submit" value="Press" /> </form>
B <b tal:content="structure here/REQUEST"></b>
Template B prints: form obj '<OrderedFolder instance at 42d9aec0>'
I need the object itself, not the string representing the object!
No can do I'm afraid. The objects you deal with live only in the Zope server. When you send a response back to a user, this is just HTML, made of strings. Based on this, the user's browser sends back a new HTTP request, again made up of strings. When this new request arrives, Zope has forgotten the previous response, apart from perhaps something in a user's session or in the ZODB somewhere. So, if you wish to keep track of an object during a sequence of requests with the user, you must make arrangements to keep the object somewhere in Zope, and to find it as each request comes in. Common ways to cope in this situation include: - Make do without an object at all; run everything with just strings until you come to the end of the process and are ready to commit to the ZODB. - Store an object in the user's session. - Store an object in a temporary location in the ZODB, and pass around a path to it in your various forms. Hope this helps. Thanks, Malcolm. -- [] j a m k i t web solutions for charities malcolm cleaton T: 020 7549 0520 F: 020 7490 1152 M: 07986 563852 W: www.jamkit.com
